GN CBM Drilling Mud System

High speed centrifuge is very important for mud purification. After some circulation, there will be more and more fine solids in the drilling mud, it will let the drilling mud too weight. In this case, high speed centrifuge is request to separate the fine solids in the drilling mud.

GNLW363 centrifuge is gear box type high speed centrifuge for fine solids separation. It has a 50hp main drive and a 15hp back drive, and use the gear box for differential speed.

For more information of GNLW363 centrifuge, you can visit GN website.

GN engineer just came back from Middle Asia, They have made commission job for a GN500 GPM mud cleaning system for HDD rig.

This unit mud cleaning unit with capacity 500GPM. It is designed per customer specified requirement and GN professional engineering standard .

The 500GPM mud cleaning system for HDD rig is including 2 phase solids separation:

1) 1 unit mini cleaner with under shale shaker GNZS703 double deck model and 8 ea desilter cyclone.

2) 1 unit mixing hopper

3) 2 units centrifugal pump one for mud transferring to desilter cone while another one used as mixing pump.

4) 1 unit mud tank divided into 2 compartments for sand trap and mud mixing tank.

Strong practicability and cost saving always make GN mud cleaning unit satisfy the customer.

Coupling type Drilling mud agitator is widely used for drilling fluids mud tank. The motor and gear box connected through coupling, and mounted on a metal skid.

Advantages of Coupling type Drilling mud agitator

1) It is easy for maintenance compared with direct connecting type drilling mud agitator.

2) It is easy to mount on the tank top on drilling mud system. The skid of drilling mud skid can weld directly to the mud tank top.

The shale shaker vibrate strongly and regularly in a certain motion, drilling mud from well head fall onto the shaker screen surface, separated under the strong vibrating force.

While go pass the screen surface, water phase and clean mud fall into the mud system for drilling, solids separated and moved away for next process.

There are 2 eccentric blocks inside the vibrating motor, users adjust the angle of the 2 eccentric blocks to get different vibrating strength.

Note that: In drilling site, the 2 motors of a shale shaker should running under the exact the same vibrating strength for a stable performance. 

Damping spring is a very important wearing parts of the shale shaker.

There usually 4 damping spring for a shale shaker. Function of the damping screen is to make the start / stop of the shale shaker more soft, to protect shaker screen and the shaker frame from strong vibrating.

A better material spring can make the shale shaker running more stable and longer the lifetime.

Many shaker suppliers, they steel damp spring for shaker. While the Chinese top 1 manufacturer GN Solids Control, they use composite material for shale shaker damping spring. It is inside metal and outside covered with rubber. More strong and flexible.
