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.

Design and Develop associated with GN Decanter Centrifuge

GN Decanter Centrifuges are very common to separate OBM, WBM or maybe SBM. GN decanter centrifuges are designed and manufactured by knowledge engineers who have been working on solids control and drilling waste management systems for many years.
Drilling Cuttings is the primary strong to pollute the going fluids in the oil as well as gas industry. The going speed runs slow if the solids in the drilling water going up. In order to keep the efficiency of the drilling fluids, it is necessary to control the drilling ensity. According to the survey, the actual of drilling fluids is often 10 or 20 times during the the drill cuttings. A small part of the drilling water is used to expand often the drilling hole. So is considered pretty cost-effective to use mechanised separation equipment to fulfill typically the objectives of eliminate the unsafe solids and decrease the use of drilling fluids to cut price.
High speed decanter centrifuge can easily separate most of the solids bigger than 2-5 microns. The right after treated solids are with less water which can save drilling fluids largely, so centrifuge has a great market inside solids control area.

The needed step for adjustment for centrifuge

A. The adjustment of the drum speed.

 The adjustment of the bowl speed is performed in  manual adjustment or centrifuge plate prescribed maximum working speed following the adjustment.

Different rated speed by installed different size wheel by diameter for driving the main belt wheel to set different drum operation speed

In variable frequency drive decanter centrifuge will paired with control panel that allow increase and decrease the drum speed.

By fine-tuning the speed of the drum, it can perform more precise solids particles separation.  It can also improve the wear of the drum, the vibration and the noise to extend the service life of the decanter centrifuge.

The separation purpose or drilling fluid solids content  is by the choice drum speed. For instance, barite recovery or processing high-density mud, it is suggested that the low spending  speed. For general medium density mud prefer choose medium or high speed.  The low density mud is ideal for using high speed decanter centrifuge.

B. The adjustment of the differential drive

Centrifuge differential speed (back drive is also refer by) in its within the prescribed scope of, do not suggest user to adjust and it can only adjust in a small range change the parameters.

Different speed centrifuge adjustment methods are remove the original auxiliary motor pulley, and reloading large diameter or smaller diameter belt wheel  Auxiliary motor pulley  change the differential input shaft speed enhancement in result of differential speed decreased. On the other hand, it can also cause differential speed increase.

Operators must understand that regular maintenance on the centrifuge such as regular cleaning the inlet and outlet by filling water or diesel depends what kind of fluid it needs process.  It is also crucial that  add grease to the bearing parts to ensure proper lubrication.  More information about decanter centrifuge pleae contrac  GN solids control.

Energy Desorption Unit TDU available in Houston

GN solid control develop new products Arctic Desorption Unit as the additional treatment equipments for GN standard vertical cuttings dryer waste management system.
According to companies feedback after using GN drilling waste management system, the actual oil content in the clippings is below 5%, in many countries, the parameter is usually acceptable for environmental regulations, but in some other country, they also have extreme strict environmental safety that they need the “number” under 1%. So they require the thermal desorption product to do the further remedy. But because of the high price with the TDU, most clients can just only rent it.

GN winter desorption unit can fit our own drilling waste management, also it can match other manufacturer vertical cuttings dryers. Comparable to the goods solids control program can reduce the drilling waste material, so the drilling waste management working performance will be increased; the goods drilling waste operations system( or vertical waste dryer system) can reduce often the oil content in the waste as much as it can, so the winter desorption unit will work better. GN vertical cuttings dryer’s files is around 3. 77%. When the cuttings dryer did not successful, you will have to pay more in the further more treatment, and the TDU effect may not match the environmental need.
TDU will be used only for oil-based drilling cuttings treatment, to get water based cuttings, GN high-G dryer shaker and also high speed decanter centrifuge will probably separate the solids really dry and ship these by truck, and recycling the fluids as much as possible. Many of us make them into modular product and make them combination inside a system to meet your several requirement for both water structured and oil based drill clippings.

Mining Fluid Purification System for Philippines

For the mining, GN have made a few customised design systems, the first one is for Turkey, the customer co-design the system with GN; then for the coring ming project, we design a very small mud recycling system for diamond drilling; then some decanter centrifuge with different layout for mining water; now another customised system for Philippine mining project.

This system contains a shaker, two centrifuges. The problems brought to us is: deep underground, have mining water, with mixtures, different particles, which destroys the pump which keep pumping the waters out to keep it able to work there. The pump is made in German, good quality, but also expensive, we want to keep it operating in good condition, and not easy to get spare parts. To sum up, we need another system to make the pump running perfectly.

Then we tried many different choices, to keep it under ground, or keep it on top of the land. To only use a centrifuge, or use many centrifuges. And questions keep coming like do we need shale shaker, do we need desnader and so on. 

With the professional help from clients’ engineer, we finally confirm the design, and also modify the present operation flow of the mining water. Then finally purify the singing water, then transport to the surface. Since the purpose is not for drinking, so do not try.

 

Also in the system, it contains two Nemo pump, which is made by German Netsch. 

Specifications of  decanter centrifuge

we have VFD control panel to achieve stepless bowl speed adjustment to enhance mud treatment performance

we use Duplex stainless steel SS2205 for centrifuge casting to improve bowl balance, centrifuge balance, as well as get better performance on corrosion resistance.

We use Tungsten carbide tiles protecting the screw conveyor impellers to enhance the performance when treating heavy mud.

When the system arrive the site, GN engineers will go to the site for the first time commissioning and also operator training. To make sure all goes well and in the right way.

Drilling Waste cuttings Decanter Centrifuge

Treatment of drilling waste cuttings for water based mud and oil based mud is one of the applications of GN solids control decanter centrifuge. In oil & gas drilling industry, decanter centrifuge is mainly used for solids control system ( to separate fine solids and recovery of barite) and drilling waste cuttings management. When it is used in drilling waste management system, it works together with vertical cuttings dryer, to separate the fine solids from the cuttings dryer discharged fluids. Sometimes for water based cuttings which with high solids content, there is a high G dryer behind the cuttings dryer and before decanter centrifuge, the purpose is to reduce the solids content in the fluids and protect the decanter centrifuge and get better performance.

The decanter centrifuge is installed on top of mud tank or on the telescopic skid. GN provide standard telescopic skid with handrails, walkways, stairs and other accessories, the feeding pump is installed on the skid for convenient transportation.

The decanter centrifuge can not be used directly in drilling cuttings treatment, because the cuttings are coming from shale shaker of solids control equipments, the solids content is too high and the solids size is too big to block the feeding tube of the centrifuge. The function of the vertical cuttings dryer is to separate the big solids and reduce the solids content, and recovery over 95% of oil from the waste. Because the screen mesh of the cuttings dryer is too coarse, most of the fine solids passed through the screen basket, a high speed decanter centrifuge is necessary for the further treatment.

Right now GN solids America has 2 units of GNLW363CG centrifuge in Houston with telescopic skid for rent. It can be used for either solids control equipments and drilling waste cuttings treatment in the whole States, welcome to inquiry us.
