Drilling fluids mixing hopper is at the last end of drilling fluids recycling loop system.

It is usually matched with centrifugal pump or shear pump..

Function of drilling fluids mixing hopper:

The unit is used to make up drilling fluid or increase total amount of the drilling fluid, change the fluid density, viscosity, and dehydration. When making up again, put the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) into the recycle tank through the jet unit.

Desander is the third phase solids control equipment.It is usually followed shale shaker and next it is desilter.

Desander usually combined with a underfluid shale shaker, hydrocylone parts (usually 10’’)

.

Underfluids shale shaker is option. Hydrocyclone parts can match to match 2 ~ 3. Cone material choose from 100% Polyurethane (PU), with longer using lift,and interchangeable with Derrick.

Flexable fast connection are available for user friendly assy.

Vacuum Degasser is one the important equipment for oil drilling mud system for separation the gas from drilling fluids to keep the balance of the mud.

GN have around 10 Vacuum degasser in stock for sale

GNCQ Series Vacuum Degassers that are able to service the needs of any application .It is usually fixed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus ensuring that the proper mud weight is pumped down hole. In doing so, the degasserss are able to aid in the prevention of potential blowouts. Unlike the traditional vacuum degasser, GNCQ vacuum degasser is a self-contained unit. The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing centrifugal pump .Moreover, GN degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter. GN also have Atmospheric/Centrifugal Degasser available as an alternative to the standard vacuum type degasser.

GN have around 20 Decanter Centrifuge in stock for sale.

With over 400 decanter centrifuge operation in the world,GN is producting around 150 decanter centrifuge every year.

Introduction of Decanter Centrifuge.

Decanter Centrifuge is a machine for the continuous sedimentation of suspended solids from a liquid by the action of centrifugal force in an elongated rotating bowl.Continuous unloading of solids from the centrifuge bowl is made possible by a conveyor which rotates in the same direction as the bowl but at a slightly different speed.

PRINCIPLE COMPONENTS for Decanter Centrifuge.

1.Centrifuge Bowl (or drum)

2. Centrifuge Conveyor (or scroll)

3. Gearbox

4. Frame and collecting vessel

5. Feed inlet and distribution

The desander should take suction from the degasser overflow tank and overflow to the adjacent downstream tank. Desilter suction should be from the desander overflow and again, overflow to the adjacent downstream tank.

Low level equalizers between the overflow and suction tanks ensure a backflow of mud as described above.Where the bottom of the cones lies several feet above the mud level in the tanks, the overflow line may create a vacuum which sucks solids through the overflows, thereby reducing separation efficiency. This can be overcome by installation of a vacuum break.Both desander and desilter shall installed on the mud tank.
