Workover Drilling Rig Mud Tank System for Africa

Recently one set of workover drilling rig mud tank system are ready for delivery to Africa. The technical configuration is as below:
1. 2 units of GNZS594J-SHBJ 4 panel shale shaker with possum belly flow divider, 4 pcs of composite material frame shaker screen are installed on the shale shaker, as the primary separation equipment of the workover drilling rig mud tank system.


2. 1 unit of GNZCQ-270B vacuum degasser, self contained, no need extra jet pump. The vacuum degasser is suitable for various mud recycling system to separate gas from mud, the purpose is to remain the specific gravity and mud viscosity, also to protect the centrifugal pump from damaged from gas cut mud. Under the atmospheric pressure, the mud enters the rotor hollow shaft through the suction pipe and ejected towards the tank wall through the windows around the hollow shaft. Due to collision and the action of the separation wheel, a thin layer of drilling fluid is formed, causing the bubbles immersed in the mud to break and the gas to escape. Through the suction of the vacuum pump and the separation of the gas water separator, the gas is discharged to a safe area through the exhaust pipe, and the mud is discharged from the mud outlet by the centrifugal force generated by the impeller driven by main motor.


3. 4 units of GNJBQ055G mud agitators installed on the mud tank for agitating of drilling mud

Drilling Mud Centrifugal Pump and Mud Agitator for Africa Client

Recently one batch of drilling mud centrifugal pump and mud agitators are ready to ship to Africa client.
The drilling mud centrifugal pump can be used as drilling mud transfer pump, mud pump charging pump, trip pump, desander desilter feeding pump, water pump, mixing pump, etc., we produced different model drilling mud centrifugal pump for different flow rate and lifting head.


The mud agitator consists of heavy duty gearbox and explosion proof motor, which is connected directly, it will be installed on top of mud tank for drilling mud agitating, to prevent the solids deposition in the drilling fluids circulation system, to ensure stable performance and uniform mixing of drilling fluids.
Features of GN G version mud agitator:
1. The helical bevel type heavy duty gearbox runs smoothly with less noise.
2. The motor is directly connected to the input shaft of the gearbox without belt transmission, the speed of the mixing impeller is constant.
3. Compact foorprint and reliable operation.
4. High mixing strength and wide agitating range, avoiding the phenomenon of current overload when the motor starts.
5. Including agitator shaft, double or single layer impeller, stabilizer
6. Except for direct connected G version mud agiator, GN also produce coupler type E version mud agitator, vertical type mud agitator.
The selection of motor power and impeller is usually determined based on the following points:


a. Mud tank type – cylinder or rectangle
b. Mud Tank size
c. Mud specific gravity
d. Rotation speed ratio
After collecting relevant information, we will select the mud agitator proper model and confirm motor power, shaft length, and impeller.
If you need more solids control equipments for mud tank system, such as mud mixing hopper, mud gun, submersible slurry pump, screw pump, shale shaker, mud cleaner, decanter centrifuge, vacuum degasser, pls contact with GN solids sales engineer.

Vacuum Degasser and Mud Agitator for China Oilfield Service Company

Several sets of vacuum degasser and mud agitators are ready for delivery to China oil oilfield service company.


GN solids control can provide different types mud agitator for different application, including coupler connection mud agitator, direct connection mud agitator, vertical mud agitator, etc. The gearbox to be used with mud agitator is heavy duty helical bevel type gearbox for reliable operation, especially suitable for heavy mud. We will install different explosion proof standard motor for different project’s requirement, control panel can be optional as client’s requirement, such as IEC EX, ATEX, CNEX, etc. The impeller size and shaft length can be customized as your mud tank dimension.
When the agitator impeller come into contact with the drilling fluids, it forces it to generate vortex motion, thereby preventing the sedimentation of solid particles in the drilling mud, achieving the effect of uniform mixing of solid and liquid phases and consistent density. The connecting plate sandwiched in the middle of the impeller can prevent the solid particles of mud from depositing in the lower part of the impeller after shutdown, thereby reducing the resistance of solid materials to the impeller when starting again, and avoiding the accident of burning the motor due to starting overload. When motor is running, it drives the input shaft of the gearbox to rotate through the rotation of the motor. The output shaft of the gearbox drives the mixing shaft to rotate through a rigid coupling, and the mixing shaft is connected to the impeller through bolts for transmission.
To select proper quantity and model mud agitator for the solids control system mud tank, we will clear the drilling fluids density, mud tank dimension, equipments list, etc. information, then we will select proper model for our client.
