GN CBM Drilling Mud System

GN Solids Control is a worldwide famous brand of mud solids control system, drilling waste management system, as well as replacement shaker screens.

This week, GN Solids Control China factory finished a mud system for a domestic project. It is a 4-tank mud system for 750hp drilling rigs.

1) The 4 mud tanks of the 750hp rig mud system are the same size with 40ft container. And the tanks are equipped with 3-runner oilfield skid. The oilfield skid is with 250mm at each tank ends. It makes the tanks easy to movement at jobsites.

2) GN Solids Control equips 2 sets Solids control linear motion shale shaker separator for the system. The system is equipped with 2 each 3-panel shale shaker, model GNZS703E. It is the most popular shaker models for oil and gas mud system from GN Solids Control.

3) In this system, the clients choose 1 desander separator and a desiler separator.

The desander model is GNZJ752-2S. It is equipped with 2 ea 10’’ desander cone. Each 10’’ desander cone is with max. 120 m3/h (528GPM) handling capacity.

The desilter cone model is GNZJ752-12N. It is equipped with 12 ea 4’’ desilter cone. Each 4’’ desilter cone is with max. 20 m3/h (88GPM) handling capacity. For totally 12 ea 4’’ desilter cone, the desilter handling capacity can reach to 240m3/h (1056GPM).    

4) The 4-tank mud system is equipped with a middle speed decanter centrifuge to recovery the barite and reduces the mud weight. The centrifuge model is GNLW452. It is a most cost-effective big bowl decanter centrifuge widely used in solids control mud systems for oil rigs.

5) And there are many mud agitators, mud guns, lights, and pumps for the system.

As more and more authorities issued more and more strict rules on the envornment protection, drilling waste management equipment gets more and more necessary at drilling rig site, especially in oil and gas drilling rig website. As the drilling fluids material various kind of chemicals, in case discharged directly. it will have really bad pollution to the atmosphere. GN Solids Control most recent design drilling waste management equipment drill cuttings renforcement unit are welcomed in jobsite. 1) The drill down cuttings solidification unit may be used to treat drilling cuttings released from the high G drying out shaker. When the cuttings through solids control shale shaker, desander, desilter treated by higher G drying shaker, the actual fluids will go to drying out shaker catch tank for more treatment, the solids through high G drying shaker can be treated by drill cuttings solidification unit.

2) The actual drill cuttings solidification device can be used to treat drilling cuttings discharged from decanter centrifuge. The liquid phase is drilling to be covered by further treatment, such as dewatering unit. while the solids phase can be treated by drill down cuttings solidification unit.

The drilling mud decanter centrifuge driven by VFD will give many benefits to the clients. The adjustable bowl speed and differential speed allows the operators to set the right G force and solids pushing speed according to the drilling mud conditions.

To design the VFD Control Panel, the contractor needs the power supply specifications. Normally it is 460V/60HZ for USA standard or 380V/50HZ for Europe and China standard. Than the pulley size of the motor and bowl side will decide the bowl driving speed at different frequency. After confirming the bowl speed formula, the contractor needs the formula for calculation of the differential speed. For GN Decanter centrifuge, the Sun-Wheel gear box ration is 57:1. So the differential speed will be the bowl speed minus the gearbox input speed and divided by 57.

For the VFD Control panel, there is different explosion proof standard. In China, it is CN Explosion proof which is close to IEC Ex standard. In Europe, it is ATEX Explosion proof. And in North America, the explosion proof standard is UL for USA, and CSA for Canada.

GN Pressurized VFD Decanter Centrifuge control panel is specially design for Zone 1 or Zone 2 standard with ABB VFD and stainless steel cabinet. The PLC smart control allows the user to operate the drilling mud decanter centrifuge by HMI screen.

GN VFD decanter centrifuge has been exported to over 30 countries and regions, GN Solids Control VFD decanter centrifuge is available in different sizes including: GNLW223C-VFD (9inch) bowl, GNLW363C-VFD(14inch bowl), GNLW453C-VFD (18inch bowl), and the big bowl big volume centrifuge with 22inch bowl and model is GNLW553C-VFD.

With more and more cooperation between China government and Russia Government, there also more and more cooperation between China companies and Russia companies. As China leading manufactures in China, GN Solids Control Ltd have more and more development in Russia.

Pump installation

Pump installation location should be near to the source and purposely to shorten the length of the suction period and prevent the suction loss. Pump installed base should be leveled, firm and secured in order to avoid vibration during operation.

 Coupling installation

The pump and motor for a long use life depends on the elastic coupling. Available steel straightedge by coupling the up and down or so, with the view straightedge and coupling the garden all parties should contact closely. Namely coupling outside garden parties should be in a straight line to make sure that the motor shaft and pump shaft coaxial angle.

 Entrance pipeline installation

Entrance piping shall be in accordance with the pump inlet matching.

Suction piping not allowed to install throttle valve, but can be installed normally open valve to reduce fluid flow disorder. To avoid suction people line produced in steam bubble, the pumping source and between pump from high to low gradually transition. If users need to pump in use suction conditions, use vacuum pump or bottom valve pilot.

Pump at the entrance line must be flat; the length of at least two times the diameter of the inlet line.

Exit line

In order to facilitate pump maintenance, the exit pipeline should be installed normally with open valve.

All line (including population line) must have their own support.

When work condition is unknown or unstable, export in pipeline must be installed throttle valve in order to ensure the pump in the design point operation.

When the pump discharge and pressure equipment connected, the throttle valve and pump must install a check valve to prevent the liquid reflux, otherwise, the return fluid can lead to damage

GN solids control produced mud handling equipments and mud tanks are mainly used for cleaning and recycling the used driling fluids from the well bore.

GN 500 GPM mud recycling system is one of the most hot sale system model for horizontal drilling directional drilling (HDD), water well drilling, CBM drilling, as well as for some small workover rigs.

Water well drilling is very important; it is not only used for human being life and industry purpose. For oil and gas drilling field, it is also very important. Before start the operation of oil drilling, the jobsite need to drill water well. As all the drilling activities need to use water. They have to ensure water supplier before start drilling oil and gas well.

One set trailer mounted GN 500 GPM mud cleaning system arrive client job site and highly commended by the clients. The GN 500 GPM mud recycling system is designed for 1000m deep water well drilling. It can also suit for 350hp drilling rigs and ZJ20, ZJ30 drilling rigs.

Cuttings Box Used on Drilling Site

Cuttings box is also called cuttings collection box that is widely used on drilling site as a temporary vessel to collect and store the drilling waste cuttings. Due to the purpose of the cuttings box, it is designed compact and easy for transportation. Once the cuttings box is full, it could be replaced by an empty one.

The cuttings box is always used on the drilling site where the mud pit is not available. In the solids control system, the cuttings boxes are always located under the solids discharge chute of the shale shaker to collect the cuttings out of the primary shaker. Same situation as the cuttings box located with the de-sander, de-silter and decanter centrifuge.

Most of the cuttings boxes are simple without a cover. And if you want move it, you need be careful as the cuttings still with large content liquid will splash out. With consideration on this, GN Solids Control designed a type waste cuttings box with a fully sealed cover on it. When collecting the cutting, the cover is open; when transportation, the cover is locked easily to prevent the splashing of the cuttings. It is an ideal container to meet the requirements of HSE regulations for hazardous waste movement. Not only for waste cuttings, also for some other hazardous waste discharges. At the bottom frame of GN’s cuttings box, the forklift loading grooves are designed for easy moving and replacing.

The ondrilling lower price of unsavory oil doesn’t hold the stage of oil and gas market, because the crude oil and gas is always needed by the modern-day world, the oil and gas associated companies still have to work around the oil and gas exploring and drilling, just try to reach this at a lower cost. That’s why inside the coming Oil Show to become held in April in The ussr, Chinese brands become more plus much more popular.

The Straight cuttings dryer can reduce the particular oil on cuttings to be able to 3% ~ 5%. Soon after VG dryer, the reliable discharged is very dry. Its easy for movement by vehicle. In some countries, it can be cleared directly with such very low OOC. If not, it can be eliminated to treat by thermal desorption unit. 2) High H dryer (also called substantial G drying shaker). The item utilizes high G drive reach to 8. 0G in order to dryer the cuttings. Substantial G drying shaker is principally used to separate water basic mud cuttings. Water bottom mud is more difficult intended for separation. The main problem to manage WBM with VG dryer is that, the mud may block the screen holder, then it cannot distinct any mud any more. Large G dryer shaker may also be used to treat oil base mud. But it can only reduce acrylic on cuttings to 15 ~ 15%, it is not sufficient.

Linear motion shale shaker is the first step solids control equipment, and it is the base separation machine for oil and gas drilling rigs. Shale shaker is a D100 separation machine. D100 means 100% separation. The particles over the separation point can be fully removed after going through the shale shaker screens. Shale shakers will be placed on Sand trap Tank. In the normal conditions, clean mud from shale shaker will fall down to the sand trap tank. We also call it shale shaker tank or shaker tank.

Mud agitator is a motorized mixer that is installed on the storage tank to keep fluid consist mixed with additive and avoid separation by gravity.  According to the experience of continues use on the field, the selection of mud mixer should consider to a few points:

1.    Rotation speed: Operators it does not want the cuttings in the mixing process splintered more into smaller debris, so the stirrer speeds cannot be high, the energizer should choose between 50~60rpm. For more than 60rpm of mud mixer, recommended the user to take a cautious on the result of the high rotation speed.

2.    Sealing: According to the feedback of use from the operator.   As mixing conditions are not ideal, the drilling fluid mud agitator shaft is not suitable for the use of end face seal, the general packing seal is also hard to use. At present, the more suitable is the use of multiple sets of V type packing. It has self sealing performance and self compensation ability, and long-term maintenance adjustments abilities will not cause lubricating oil leakage problems.

3.    The impeller: There is a variety of mud mixer impeller, but it must take consideration that  a small diameter of the blade with high speed of mixer motor have the small amount of circulation, shear force, and therefore does not apply to the use of drilling fluid solid suspension. Therefore, the diameter of the impeller should be consider larger. Second, pay attention to the turbine type impeller has been widely used in the drilling fluid mixer, which is the best open type turbine, because there is no central disc, not to hinder the mixing of the upper and lower liquid phase of the impeller.
