HDD Mud Recycling System with Decanter Centrifuge

HDD drilling is short for horizontal directional drilling project, it is widely used for the pipeline work for the oil and gas transporting and etc. Normally, the drilling mud recycled from the HDD machine is to be reserved in a mud pit and the mud cleaning system, which is used to treat the mud to be next time use, treats the drilling mud from the pit and storage the well done mud in the tanks.

Equipment needed for the HDD mud recycling system:

In a traditional HDD mud recycling system, there arenormally 3 phase of separation equipmentincluding shale shaker, desander cones, desilter cones and mud mixing unit for adding new chemicals into the drilling mud, normally 2 jet mixing hoppers and mixing pumps. But now, as the environment demands and the cost pressure for the contractors are becoming more and more important, a lot of HDD contractors are taking decanter centrifuge into consideration in order to get better separation result and lower the mud weight.

What is the main function of the decanter centrifuge used for the HDD drilling mud system?

1.       The centrifuge helps to minimize the negative effect on the environment.

2.       The centrifuge helps to reduce the weight of mud.

3.       Centrifuge helps to lower down the total cost on mud.

GNLW452C or GNLW452C-VFD is a very suitable model of decanter centrifuge to be used for the HDD mud recycling system. It is big bowl centrifuge of 18 inch bowl diameter and the speed of 1800 RPM is efficient for the HDD works, in China, the largest HDD contractor CPP, always use GNLW452 in their mud cleaning systems.

The centrifuge feed pump could transfer the mud from the storage tank to the centrifuge and after the separation, the mud could directly fall back to the same tank, cycling like this helps to reduce the mud weight. Or, there could be another storage tank to collect the drilling fluid from the centrifuge.

GN Closed Loop Zero Release System

As the restrictions with regard to dispose the drilling waste material from the oil and gas drilling is now more and more strict all over the world, particularly in developed countries and regions, the drilling companies as well as the oil related service businesses are more and more careful in disconnection with the drilling waste. It may be a trend that so-called zero discharged solutions is required for the oil and gas drilling market.
Among all the solids control and waste management producers in China, GN Solids Control is the first to create and develop the zero-discharged closed loop for treating the actual drilling cuttings. See specifics as below:
1 . GN complete solids control system including GN shale shaker, GN mud cleaner, GN middle speed decanter centrifuge and GN high speed decanter centrifuge. all drilling cuttings discharged from above mentioned products are collected by GNSC series screw conveyor for even more treatment instead of disposed.

installment payments on your GN drilling cuttings squander management system, it is useful for further treat the drilling cuttings. because the drilling cuttings from the solids control system are still wet. This system includes GNZS594HGE-LD drying shakers and GNLW363CG high speed decanter centrifuge for WBM solely. Or, GNCD930C vertical cuttings dryer and GNLW363CG Decanter centrifuge for both WBM and OBM.
The above mentioned two systems are enough for the majority of cases.
3. GN Dewatering unit and high speed dewatering centrifuge GNLW363CG-VFD. Dewatering product is a system for foloculating the extra fine particles in to larger ones in order to be connectors by the high speed decanter centrifuge. Like the item 2 is approximately the further treating with regard to drilling cuttings, the dewatering unit is for further healing the liquid.
4. GN Solidification unit and TDU Unit are respectively utilized for finally dispose the very well dried drilling cuttings in the drilling cuttings waste management system.

GN Shear Pump in Mud Recycling System

All large capacity drilling projects such as oil propane drilling, no dig drilling for pipeline laying along with water well drilling want drilling fluids when doing the actual drilling job. There is 1 type equipment naming shear pump that is an ideal option for drilling fluids mixing. We could see the drilling water as the blood of the drilling equipment.
Here, how to make the particular drilling blood clean and then let the blood perform well is so crucial to all the drillers. It is identified that the drilling project have to have a drilling fluids recycling system, or we call that mud recycling system. Just before start drilling, we need have the mud recycling system prepared. On the other hand, we need the drilling fluids to be ready. Often the drilling fluid is a mix off water/oil and some mud elements like barite, bentonite, plus some other chemical agents. Among the list of various mud materials, often the bentonite is the most important just one and the consumption is quite significant. Meanwhile, the bentonite is a polymer which is difficult to resolve into the drilling mud bottom. Then how should all of us resolve this problem? Bingo! We want a shear pump. On account of the special design of often the impeller, the shear pump could cut the polymer bonded into very small pieces to ensure these materials could resolve into the water easily. An increased efficiency shear pump will certainly make the consumption of bentonite reduce a third. Oh my god! Excellent large cost saving.
It is not the only advantage to use a shear pump to cut the polymers. Once the drilling started, often the solids control equipment will start running. When the utilized drilling fluid comes out from well whole and circulation into the shale shaker, the actual mud recycling process is definitely beginning. If there is much longer strips material in the going fluids, the screen are going to be blocked which leads to decrease of polymers.

One thing the going fluids engineers need give consideration is the shear pump are unable to run without fluids in the pump. As you know, the shear pump is use centrifugal type pump, it have to have run with liquid to lower centrifugal force so that the essential fluids can be transferred continuously. Another, the shear pump should not be used to transfer used/active mud, as the cuttings in the utilized mud will definitely damage the particular pump parts.

Choosing a Suitable Screw Conveyor

A screw conveyor is usually called as auger, due to screw inside the long situation used for transporting the material from place to another, it is known as screw conveyor. It is common products used in oil and gas drilling solids control system and waste management systems, but amongst many suppliers, how to choose an appropriate screw conveyor for your task?
What factors should be considered think about an Auger/ Screw Convyor?
1 . HSE is always the 1st factor to consider for a sensible client. The design of the bolt conveyor /auger is human being oriented or not is very important. Are rotating parts well taken care of? Do the screw conveyors /augers have the protecting cover? GN Solids Control is a company that is HSE certified and GN’s auger is accepted through many international famous corporations who have strict HSE criteria.

2 . the material used for often the screw conveyors /augers, particularly the impeller. Because the going cuttings are of very hardness, and they may simply damage the impeller if your impeller is not strong sufficient. GNSC series screw conveyors /augers use 16 Mn as impeller material.
three. the flexibility when using the screw conveyors /augers. Because the layout of each one project is not the same, the consumer or end users have to re-arrange the existing equipment a bit towards the requests of each project. When the distance is not same, that is always the cases, they must reduce or add the particular screw conveyors. GNSC collection screw conveyors could meet up with such demand easily since GN’s screw conveyors were created as 12ft long for each one section, and the first segment is with the motor while last one has the gear-box, besides those 2 segments, other middle sections can be easily interchangeable. It means, you can utilize more or less sections of conveyors to attain different requested distances.

GN Solids Control sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , screw pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc .For more info, please visit GN website: http://www.gnsolidsamerica.com

Cleaning cycle of drilling fluid

Concept: The drilling fluid cleaning cycle is to remove the harmful solid debris, reserve the clean drilling fluid to meet the demand of drilling fluid spec under the drilling process. Drilling fluid cleaning system is the term of all drilling fluid solids control equipments used in the oil drilling.

Function: To prevent the oil well from clogging, breaking, and decrease the drilling torque and friction resistance, reduce the pressure fluctuations of the hollow suction, increase the drilling speed, extend the drilling bit life, and reduce wear and tear of the equipments. Methods: The common methods are mixture-thin methods, swap methods, machine methods and additive-chemical methods. Use different separation function machinery is  machine method is by using screening, centrifugal separation and gravity separation to separate the solid phase according to the different size and density, therefore, to control the solid phase in the drilling fluid.

1 The technical process of the drilling fluid cleaning system and the combination of the fluid cleaning equipment.

The technical process of complete group of drilling fluid cleaning system should meet the specification of five level solid phase control (screening, degassing, desanding, desilting, centrifuge) and the provoke the drilling fluid. The merger of each solids control equipment is very important, the through out of one to five level of mud cleaning equipment should each corresponding, and the spacing of the proper distance were is appropriate.  To have certain overlap during the cleaning process, make the smaller particles of the processing incomplete in the up one had been disposed in the next solids control equipment.

2 Drilling fluid cleaning cycles

The mud back from the opening of well through the pipeline and conveyed the drilling fluid to the shale shaker. The first phase of cleaning completed by shale shaker, then entered the mud tank, the drilling fluid flowed from the mud tank through the tank slot into the desander and desilter (if detect the exits of gas, vacuum degasser will process to remove the gas) the fluid after processing of the centrifugal steps and through the tank slot enters the inhalation cabin.  The cleaned fluid then will reuse for lubricate and cooling the drill bit.

Drilling mud tank design concepts

The level of drilling mud tank must be big enough to support the utmost cycle amount of the drilling mud within the oil well drilling process, and also have enough mud reserve capacity.  Simultaneously the tank also provides the capabilities of taking part in cycle and manipulating the oil well just in case of the emergency. Recently, using the developing from the global marketplaces and also the growing need for drilling fluid solids control systems by drilling craft, the drilling mud tanks possess the need for boost the volume size.

When the drilling mud tank size is increasing, the price of moving drill rig and drilling fluid is going to be elevated too. Because of this, reasonable cubage may be the goal which went after by finish-customers. Based on the well drilling practice by many people years previously, it uses the technique of calculation of drilled well whole cubage or drilled well casing cubage to calculate the effective cubic consists of from the drilling fluid solids control system generally. The outcomes of these two techniques of calculation are believed.

In some solids control system, how big the only drilling mud tank and the quantity of the cycle  within the tank are made the decision through the height from the derrick substructure, the neighborhood transportation situation, and also the effective dealing with amount of the drill rig needed, etc...

The top mud tank must have enough space to set up needed solids control tools, mud agitator and drill rig transfer pumps. Furthermore, the configurations from the connected flow type of the drilling mud, add-ons, pump inhalation, water pipeline and just various tools needs be thought. The level of every storage mainly rely on the set-up space of solids control tools like shale shaker, desander, desilter, decanter centrifuge, along with other auxiliary devices too.

The designing of GN mud tank

GN Mud tanks are broadly utilized in solids control area, even though the functions might appear quite resembles to storage the muds or drilling wastes for various separation steps, many of these tanks play an important part in solids control system.

Today we’d like to share some info regarding how to design a GN mud tank roughly in a fast way.

To create a GN mud tank, we have to understand how our customer likely to transport to their region or even the ship approach to their country. Usually you will find different land transportation limits in a variety of nations, so these restrictions are the initial amounts we have to consult with our clients. But many of these restrictions should be inside a container.

Therefore the second factor has to consider the ocean transport way. Will the solids tools be placed into container? Will the devices be made to exactly the same size according to the container? Or will the devices be shipped in large quantities? Rely on different shipping techniques; the tank could be designed into different limited dimensions.

When the tank is defined right into a container, the biggest width is 2250mm (including sand cleaning doorways and lifting lugs) When the tank was created like a standard container, compared to biggest width is 2588mm Or maybe the tank is a large capacity tank, the biggest width is 2950mm.

For these tanks, we usually designed all of them with integer number, from 4m to 12m. Its better the space isn't beyond 13.5 m. When the tank (length is 6m) is created into 20 ft. container, the space ought to be 6058mm while for tank (length is 12m) is converted into a 40 ft. container, the space is 12192mm. Skid-mounted tanks should plus 250mm both in finishes from the tank (that is 500mm as a whole), the ultimate length is by using .5m.

Motor Control Centre For Drilling Site

The thermal desorption system is controlled through an Allen-Bradley Programmable Logic Controller model PLC5/20 mounted inside the free standing control container. The process can be monitored and controlled through the use of PC/AT Operator Interface Platform on a desk top computer and viewed on a full 19” monitor.  Process conditions are continuously monitored by an array of instrumentation installed on the process equipment. The state of the instrumentation represents real-time conditions of the process and allows for process information to be reported by the PLC to the display screen. The micro process or, as an integral part of the PLC, monitors the information received from the input field devices, performs the routines programmed in the ladder logic code, and delivers commands to the output instruments to automatically control system operations.  The operator inputs required process criteria directly to the terminal to specify the conditions of the system operation. The PC based software relays this criteria to the

PLC, which performs the logic functions to meet the specific process requirements.

Equipment status, process criteria and alarm conditions are displayed on graphic display screens within the operator’s interface terminal, allowing the operator to perform process and machine diagnostics. The graphic display alarm and process screens also provide operators and maintenance personnel with information that aids in trouble shooting the alarm condition. The control system is user friendly and employs asimplistic method of interfacing the operator with the equipment. DC5424

When you received inquire from clients, you need check if they have motor control centre , cause this will affect price and design for electrical control system for all motors on solids control system a lot. If they don’t have motor control centre, you will need include all control component for all your motors but if they do have a motor control centre, you need supply control componenet for motors larger than 30KW to save cost for your clients.

The Primary Safe Unit ---- Mud Gas Separator

We're able to begin to see the mud gas separating set up in many drilling rig jobsite. Regarding to complicated geologic atmosphere of drilling site, mud gas separator can be used for separating the hazardous gas in the drilling liquids. Not just mud gas separator can be used for oil & gas drilling site, but it is also requested the deep mining drilling jobsite.

GN mud gas separator’s working principle

The drilling liquids/mud from lower hole adopts mud gas separator (poor boy degasser).Because of the gravity pressure; the mud drops lower around the 1000mm diameter vessel of poor boy degasser. Mud collides on buffer plate of pipe therefore the harmful gas is going to be relieved in the drilling liquids. Clearly, gas flows to the peak of 8 inch vent line that is associated with the flare igniter to lose out. Normally, flare ignition system is about 160 foot from the poor boy degasser to make sure the safe distance burning. Meanwhile, the mud would go lower and gathered at the end of mud gas separator, and subsequently flow towards the in to the solids control system including shale shaker, desander, desilter and decanter centrifuge etc

Why we decide GN mud gas separator?

1.GN is recognized world-wide for precision, sturdiness, from simple to complex and standard to personalize to be able to design and manufacture probably the most reliable mud gas separator .

2. GN design, application, and manufacturing engineers have designed custom items to suit each and every application. For example, we're able to flat fold the mud gas separator around the skid for simple transportation.

GN supply the economic, atmosphere and safe closed loop system including mud gas separator, shale shaker, desander, desilter, mud conditioner, vacuum degasser and decanter centrifuge etc. We not just supply you just one unit or system, but additionally centered on the very best solution for the mud, fast response and convenient spare part delivery. Give us a call right now to not waste time and cash.

Poor boy degasser for oil & gas drilling

Functions of Poor boy degasser for oil & gas drilling

Poor boy degasser, also called mud gas separately, it is a normal equipment in mud solids control system for onshore and offshore rigs. We can see from the name, the main function of poor boy degasser is to separate gas from drilling mud. There normally big quality air bubble in the drilling mud. The air bubble may damage the solids control equipment, like mud cleaner, desander, desilter. Another reason, and the most important reason, there normally dangerous gas consisted in the air bubble, if it is comes out with mud and spread the environment, it will make pollution and hurt the operation people at jobsite.

Different design Poor boy degasser for onshore and offshore oil & gas drilling

There mainly 2 types design Poor boy degasser for onshore and offshore oil & gas drilling.

Design 1: Atmosphere type poor boy degasser

Features of Atmosphere type poor boy degasser: there will be 5~10 m or more longer vent line on top of poor boy degasser. It is used to pipe the gas into the atmosphere directly. 

Design 2: Ignition type poor boy degasser

Features of Ignition type poor boy degasser: Ther dangerous gas in drilling mud is H2S. It is combustible gas. After fire, it changes out to harmless gas and can be discharged directly. There will be 50m ~ 100m vent line to guide the gas to remote area. There will be a flare igniter connected with the vent line and fire the gas while it comes out. 

Flare ignition Device for Poor boy degasser for onshore and offshore oil & gas drilling

As a kind of security and environmental protection device, the flare igniter can be used to make the harmful gas ignited and burned to prevent it pollute environment. The flare ignition device, apart from being used in the refinery and gas distribution station, can be matched with Mud Gas Separator.

The problems and solutions about shaker screen

Shaker screen blinding takes place while particles of solids being screened embed in a screen hole. This usually appears while drilling fine sands , for instance, in the Gulf of Mexico. The right after sort order is observed in the course of screen blinding.

1.  When a brand-new screen is set up, the circulation drilling fluid drops through the screen for a short distance.

2.  After a period of time, the fluid endpoint moves to the end of the shale shaker.

3.  In a very short time this happens, the screens are changed to get rid of the fast discharge of drilling mud from the end of the shaker.

4.  Soon after the screens have been washed, fine grains of sand which are lodged on the screen's surface can be discovered. The surface area of the screen will resemble fine sand paper because of the sand particles lodged in the openings.

One common approach to the problem to screen blinding is to change to a finer or coarser screen that the one being blinded. This strategy is effective if the sand which is being drilled has a narrow size distribution. Another method is to change to are rectangular-shaped screen, although rectangular screens can also blind with multiple grains of sand.

Blinding – the “plastering” of a soft material over and in the mesh, rendering it blocked. Remedy wash with high pressure fluid using the base fluid of the drilling fluid. If this fails, fit coarser screens temporarily.

Plugging – the blocking of the mesh by a particle (usually sand)  fitting into the pore throat of the mesh. Remedy - wash with high pressure fluid using the base fluid of the drilling fluid. This is best done from beneath the screen . It is often successful to place a fine screen on to reduce the “near size” plugging.
