The VCCS offers a safe and efficient means for containing drill cuttings after drilling mud recycling at a rigsite. The movement of air through the system allows the collection of drill cuttings and other drilling wastes, such as centrifuge waste and pit cleaning operations.
The system can collect wastes fromthe shakers and centrifuges or it can be configured to collect waste from pit cleaning operations.
CBM drilling mud normaly water base mud, a decanter centrifuge will help to separate fine solids 2-5 microns. Main purpose to separe fine solids:
1) Keep good mud weight
2) Keet mud densitity
3) Avoid mud get weighter and weigher which desilter can’t separate

Cuttings blowing pump ( CBP ) blows drill cuttings and centrifuge waste from a collection point on the rig to a temporary bulk storage tank on the rig. Benefits of CBP
1) High capacity in excess of 35MT per hour
2) Allows cuttings to be blown straight to a boat
3) Reduces exposure to drilling wastes on the rig
4) Carane lifts are minimised, reducing the risks associated with lifting numerous drilling waste containers from the rig to a boat
GN another 1000gpm mud recycling tank system is on jobsite now. Main equiupments:
1) 2 sets GNZS703 shale shaker
2) 1 sets desander
3) 1 set desilter
4) 2 mud tanks
5) 1 set decanter centrifuge
6) Attachments
Several factors may contribute to premature shaker screen failure. Most failures result from improper screen installation or damage to the shaker itself. Cracked or warped shaker beds, which may result from many years of continuous use or improper maintenance, will cause poor vibration patterns. This may cause improper maintenance, will cause poor vibration patterns. This may cause improper solids conveyance, which in turn, may cause solids to agther on certain areas of screen, wearing holes in that ssection. Damaged bedgs may also affect the tensioning ability of the tension system, including flexure in the shale shaker screen.
