GN Nodig Mud Recycling System

In oil drilling, their maybe 2 stage centrifuge for solids control slystem. The first centrifuge recovers barite and the second centrifuge dries it’s centrate and recovers valuable fluids.

For 2 stage centrifuge to be efficient, the first centrifuge must make a god separation since most of the solids in it’s centrate will be discarded.The poorer separation, the more barite will be carried over in the second centrifuge. Similarly, the second centrifuge mud operate at the highest possible G force to remove the most solids.

GN just back from Indonesia oil show with great success after shown one set of GNZS703 shale shaker. It’s specification as bellow:

1) Model: GNZS703

2) Treating Capacity:500GPM

3) Vibrating Motion: Linear Motion

4) Screen Panel: 3

Centrifuge can unweight drilling mud.

1) When processing the active system, the centrifuge feed should be taken from the desilter discharge compartment

2) Provide enough centrifuges to process at least 25% of the circulation rate

3) Run at max bowl RPM to achieve highest G Force and best separation

4) Operate the centrifuge just bellow the flood out point

Decanter centrifuge is a very important part for whole machine to unweight drilling mud.

ZJ30 solids control system normally contains shale shaker, desander, desilter, decanter centrifuge, poor boy degasser,vacuum degasser, mud tank, pump, etc

ZJ30 solids control system is designed for 3000m oil and gas drilling rig or work over drilling rig.

A sand trap is the setting compartment located downstreatm of the  shale shakers. It should be the only settling compartment and preferably should not be used in closed loop system. It’s main function is to remove large solids that might plug the downstream hydrocyclones.. With the fine screen capabilities of today’s shale shakers, the sand trap mainly serves as a back up should the shakers be bypasssed or operated with torn screen.
