Water properly drilling rigs are popular for oil and gas drilling industry, for normal lifetime as well as industries.
Take the oil and gas drillingfor example , water is the needed material for drilling actions. Water is request for you to for drilling fluids mixing, for tank cleaning, intended for flush, for equalizing nicely pressure, etc… There will be different ladies involved for drilling routines; Water is also the essential substance for the rig peoples. Often the rig sites are normally a long way away from human area. Effectively well drilling is the most rapidly and most convenient way for water supply.
GN Solids Control engineer just came back from the middle east job web-site. He finished the first time ordering and training of 1 fixed GNMS-500G water well drilling mud system. The 500GPM mud system is design and style and made for their oil rigs.

The system is composed of just one deck linear motion shale shaker, a hydro cyclone desilter separator, a drillingfluids mud mixing system, giving pump, mixing pump, the particular explosion proof electric control system, trailer skid mud tank and electrical lights systems.
For a compact design and style, GN put the feeding pump for hydro cyclone desilter, and the mud mixing pump on the skid.
In order to get an even bigger usable capacity, GN developed the mud tank together with 3 m width. With China, but also in many various other countries, 3 m may be the normal width limitation regarding inland shipment. GN produce all the sand gates build-in type. In this case, it will not on the tank width scope.
Customers request a mobile model for fast movement. Just to save the cost of clients, GN Solids Control recommend client in order to source trailer skid hereabouts and buy complete mud system from GN. GN Solids Control customize the system suitable for trailer skid. You will find container corner blocks each and every tank corner.

1. To make sure the operation of the shale shaker and normal usage life on screen, the operator need to make sure parts like wedges, screw cap bolt and springs on the shale shaker are installed correctly with no signs of wrongdoing. The operator installs the screens according the operation manual provide it from the seller.
2. To get full usage of the pre-tension shale shaker screen, operator need to ensure the rubber parts of the shale shaker is fully intact and show no sign of damage. Shale shaker screen is wear and tear parts and it will be needed for replacement after normal usage. If wear-down speed is faster than normal, then check all the moving parts of shale shaker is functioning properly and secure the screens correctly.

3. Lubrication and consist maintenance the shale shaker moving parts base on the operation manual is the must to ensure proper operation.
4. If the operator uses an OEM shale shaker screen that have not been pre-tension treatment, it is the must step that need to perform before usage.
5. If the drilling fluid flow out of the pore or damaged place, then cuttings can’t be removed. Any screen with holes or be damaged must be changed immediately, the hole and the damaged place can be sealed up by the panel. The screen must be changed as soon as possible, make a plan before the replacement to reduce the stopping drilling time, you should prepare the tools and screen before beginning to replace, if because the shale shaker is not operating, it will increase the cuttings content. It’s best to exchange the screen in a single period if possible. Need to stop the pump at the emergent time, stop drilling so as to replace the screen of shale shaker.
6. Any problem please fell free to contact us and learn to know our other products including mud agitator, decanter centrifuge, desander, mud tank ,drilling waste managent, drilling mud system etc.

Mud transfering centrifugal pump in GN’s product line range from 20~320m3 by flow. This centrifugal pump is designed to handle abrasive, viscous and corrosive fluids in drilling or industrial slurry applications. Comparing with conventional pumps, GN’s centrifugal pump has an exceptional performance by large volume, high temperature capabilities and easer to maintenance.

GN Mud Transfering Centrifugal Pump

Centrifugal Pump Structure and Parameters

With outlet 2″-6″, GN’s centrifugal pump has a head capacity range from 12m to 62m. It could be working well in the tempreture span of 100℃(-40℃~60℃).
Strong and thick pump housing design of ring runner shape to eliminate the turbulence and cavitation within the pump housing. The small distance between the impeller and the housing to be the same at all points as the centrifugal design.
In order to reduce the turbulence, lower radial and thrust loads, and provides a smooth flow of fluid through the pump, the impeller is designed for open-vane. Aslo thie design allow fluid leaving the impeller to blend with recirculating fluid to reduce abrasive wear of the casing. By using O-type oil seal to protect the no exposed shaft threads, the lifetime of the pump largely extended.
Worth to mention is that all GN centrifugal pump is using mechnical seal. All metal parts are made of 316 stainless steel. Elastic part are manufactured from viton. Both rotating and stationary seal faces are tungsten carbide.

Centrifugal Pump Functions

For drilling application, GN centrifugal pump could be used for mud transfering, mud mixing and shearing operations, desanding and deislting, degassing, supercharging, centrifugal feed, mud cooling tower and wash down.

In solids control system, GN’s centrifugal pump has below applications:

  • Mud transfering  By locating the centrifugal pump on the mud tank skid, the drilling mud could be transferred from tank shaker compartment to the Mud Cleaner for treatment by hydrocyclone.
  • Mud Mixing   Combined with a venturi type hopper,  the centrifugal pump could be used to shear the bentonite powders and mix the new clean drilling mud.
  • Charging pump   Connected with the mud pump unit, centrifugal pump could transfer the clean mud to mud pump, then from mud pump back to the drill rig.

Besides the mud transfering pump, GN could also offer slurry pump, mono pump for Decanter Centrifuge, and shearing pump for shearing large drilling fluids chemical particles. For more information about GN mud transfering centrifugal pump, please leave a message or contact with us.

In 1 set complete drilling mud cleaning system, we could find six pipeline system. They are Overflow launder pipeline, clean water pipeline, mud gun pipeline, active mud suction pipeline, mud mixing pipeline and drilling hole mud replenishment pipeline.

Overflow launder pipeline is the most important pipeline in the mud system. From the Shale shaker compartment fo the tank, there will be a launder uphill through the desander tank, desilter tank in order to prevent the drilling mud overflow out of the tank.

The clean water pipeline is used to clean the tank, it is connected with the clean water tank or a water faucet and installed opening controled by valve in each tank.

Mud gun is always powered by mud pump in a mud system for oil drilling rig. The high pressure could transfer the active mud to each tank from the begainning of the desilter tank to make the replenishment or prevent the mud sediment. While in small mud systme, the mud gun often powered by mixing pump. Some mud system will have a trip tank, also we will install mud gun there.

In large mud system, mud pump could suction the active mud from every tank behind the desander tank. All the tanks storaging active mud is connected by the mud suction pipeline.

Mud mixing pump is used to mix the drilling mud in the tanks. Where there is the active mud in the tank, the mixing pump could suction it, after treatment by adding some drilling chemical then transfer them back by mud mixing pipeline.

the drilling hole mud replenishment pipeline is connected to wellhead, when the drilling bit raise out of the hoel, the drilling mud will be pump into the drilling hole to keep the well pressure and protect the well wall. When the drilling pit again down, the drilling mud will backflow to the trip tank.

The above mentioned six pipeline system could be find in 1 set complete large mud system and all of them functioned irreplaceable. Welcome for your comments and let’s learn it together

Triplex mud pump is a reciprocating piston/plunger device designed to circulate drilling fluid under high pressure (up to 7500 PSI) down the drill string and back up the annulus.

Mud pumps come in a variety of sizes and configurations but for the typical petroleum drilling rig, the triplex (three piston/plunger) mud pump is the pump of choice. Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. A later development is the hex pump with six pistons/plungers.

Chinese Triplex Mud Pump

Chinese Triplex Mud Pump

Mud pump consist of two main parts, the fluid end and the power end.

The fluid end produces the pumping process with valves, pistons, and liners. Because these components are high-wear items, modern pumps are designed to allow quick replacement of these parts.

To reduce severe vibration caused by the pumping process, these pumps incorporate both a suction and discharge pulsation dampene. These are connected to the inlet and outlet of the fluid end.

The power end converts the rotation of the drive shaft to the reciprocating motion of the pistons. In most cases a crosshead crank gear is used for this.

National Oilwell Varco’s F-1000 Mud Pump is rated at 1000 input horsepower (746 kW) at 140 strokes per minute, with a 10-inch (254 mm) stroke.  Multiple liner sizes allow pressures and volumes to handle circulation requirements in deep drilling applications.
