Geothermal energy drilling and Gas and oil drilling

Geothermal energy drilling and gas and oil drilling is extremely similar. Both of them use drilling rigs and special technologies to investigated subterranean assets.

Geothermal energy drilling features and clarifications

Geothermal energy drilling is really a drilling technology accustomed to exploration and growth and development of geothermal energy subterranean. Per different objective, geothermal energy drilling rigs drill different depth geothermal energy hole. Geothermal energy drilling is mainly used in gas and oil drilling rig or core drilling rig.

Based on the difference of liquids temperature geothermal energy drill, you will find below different kind of geothermal energy drill:

1) Cold geothermal energy drilling (warm water type), temperatures are less than 90 DEG C

2) Middle temperature geothermal energy (moist warmth type), the temperatures are between 100 to 150 DEG C

3) Hot temperature geothermal energy (steam type), temperatures are greater than 150 DEG C.

People pay increasingly more attention on geothermal energy assets and it is exploration. Geothermal energy assets can be used as energy generation, home heating, drying out industry, green house cultivation, artificial breeding and health, bath etc.

Gas and oil drilling features and clarifications

After exploration and located oil blocks/oil area, people use gas and oil drilling rigs and special equipment and technology to drill holes in surface selected, lower or side drilled a particular diameter round perforation, and drilling towards the subterranean gas and oil layer.

Per the drilling rig capacity on drilling depth, gas and oil drilling rig could be split into below fundamental models: 2000m drilling rig, 3000m drilling rig, 4000 drilling rig, 5000m drilling rig, 7000m drilling rig, 9000m drilling rig and max. 12000m drilling rig.

Based on the energy system size, gas and oil drilling rig could be split into below fundamental models:

1) Mechanical drilling rig, e.g.: ZJ50L drilling rig, ZJ40K drilling rig.

2) Electrical drilling rig: e.g.: ZJ70D drilling rig, ZJ50DB drilling rig.

3) Mixed energy drilling rig: e.g.: 40LDB drilling rig.

GN Mud System for 2000HP Drilling Rig

Each year, GN Solids Control design and manufacture many teams of oil and gas solids control devices for customers from abroad and domestic market. For GN Solids Control, GN can offer mud recycling systems for drilling rigs for example 650 HP, 750HP, 1000HP, 1500HP or 2000HP.

Just take 2000HP drilling rig for example, GN mud system can cope with 300m³/h. Usually, GN mud product is composed with 7 mud tanks: trip tank, shale shaker tank, centrifugal tank, mixing tank, shearing & reserve tank, and in addition the reserve tank. Suction tank can also be utilized while the whole system connects using the ruthless mud pumps and provide drilling liquids for that drilling rig.

For that trip tank, the max overall dimension is 6.5 X 2.95 X 2.37m, that is about 12m3. The trip tank is outfitted having a mud agitator and mud gun.

The shale shaker tank and the centrifugal tank can also be known as the treating tank. Both of these tanks are outfitted with shale shaker, mud cleaner and centrifuge to split up solids previously mentioned 100 micron to five microns. With these solids control devices, the mud could be released, and clean drilling liquids could be utilized again.

Because the drilling liquids is essential for each drilling process, to add some chemicals for example like barite, bentonite clay or something like that else. So a shearing tank and mixing tank can also be very essential for this solids control system.

After fully shearing or mixing the drilling liquids, the drilling mud could be storage inside a tank and prepared for more use. And also the mud agitator is playing an essential part in drilling liquids storage.

Whenever we connect two parallel ruthless mud pumps using the mud tank, we usually named the tank like a suction tank. Both of these mud pumps can suck the drilling liquids in the mud tank and supply clean drilling liquids towards the rigs.

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.

See Dried Drill Cuttings in Water-based Mud after Handled by GN Vertical Cutting Dryer

Recently, after i cited one of my clients on GNLW decanter centrifuge, he explained he also requires a drying solution of mud treatment. Certainly, GN solids control can offer a total solution. Last year, GN has shipped several drilling waste cuttings management system, the first is for an African customer, the other is for Cyprus customer. And lately, GN offered 4 models of drilling waste cuttings management to Russia for Baker Hughes.

Regarding to drying solution, there tend to be two ways. The first is applying High G force linear motion shale shaker that is usually utilized for water-based drilling mud for which is much harder to manufacture, the second is vertical cutting dryer that is used for oil-based mud. As the problem for dry drilling waste water-based mud with a high G pressure linear motion shale shaker would be that the shale shaker can't provide the expected drying effect.

While, GN Solids Control has shown in CNPC job site that GN second generation vertical cutting dryer could handle water-based drilling waste, and provide expected results. It really is break-through news, meaning companies may use GN vertical cutting dryer to exchange high G pressure shale shaker to deal with water-based drilling waste to obtain more satisfying results.

After treated by GN vertical cutting dryer, solids discharge in the bottom opening is proven as with the next pictures. The drilling waste liquid can be dealt by GN high-speed decanter centrifuge. Next, the liquid could be used again within the drilling mud system. This vertical cutting system reduces most of cost for drilling companies to mixing drilling mud, and save lots of money to dispose the drilling cuttings waste.

The choice of dimension for Mud Tanks

Mud tanks are the base of a drilling mud system, regardless of oil and gas drilling mud solids control systems, or HDD or CBM or TBM, or whatever.  When there's drilling and there mud can be used, it's important to possess mud tanks.

It's not a difficult job for an engineer to create a mud tank using the modern soft-wares like AutoCAD or three dimensional drawing tools, but exactly how to assist the client to obtain an ideal tank in the beginning time? May be the asked for storage capacity of tank enough for design? GN Solids Control shares some suggestions.

1. When the first is requesting a solids control system for oil and gas drilling, this means the drilling mud comes from the well hole directly. Within this situation, we have to consider the weir height of shale shaker when selecting the peak of mud tanks. If the entire height of shaker weir and tank height is simply too large, it's possible that the mud can't fall in the pipelines from well mouth. This tip is particularly for workover rigs. For meeting customers’ different demands, GN has designed its shale shakers to supply several optional weir types.

2. Throughout transportation, what equipment within this system might be taken apart, while which equipment has to be fixed on tank and moved together? Actually, mud agitators will always be on mud tank, while shale shakers and mud cleansers will always be removed temporary.

3. Can there be any legal requirement in the users’ local for that biggest width or biggest height? This should be taken care.

4. just in case of worldwide business, the machine have to be shipped by ocean. What type of ocean shipment will the consumer accept?

Obviously, the storage capacity can be the fundamental requirement which needs to be meeting in the beginning stage. GN always believes to supply the clients with best and appropriate solution.

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.
