Shale Shaker for Sale

GNZS703 shale shaker produced by GN solids control has been widely used in oil & gas drilling. GNZS853 shale shaker is normally used for drilling cuttings treatment.

Below is the photo taken in South America oilfield drilling site. They use GN shale shaker to separate the large solids from the drilling fluids and get clean mud for reuse. Also they user GN shale shaker as a underflow shaker to help the performance of desander cone & desilter cone.

To know how to operate GN shale shaker is much more important, also the maintenance. Only if you operate and maintain it according to the manual, you will use it same with some famous brand  shale shakers.

1 Angle adjustment

The angle can be adjusted both under running and off condition.When delivered ,the deck is horizontal(0°) While operating with the same shaker screen, according to the worksite mud property, and feeding capacity ,by adjusting the deck angle in order to improve the treatment result .When the drilling mud run off, enlarge the deck angle to solve the problem. Angle adjustment range -1°~+5°rated angle 0°~3°

2 Pool configuration

A better pool configuration can maximize the screen area and such achieve better result. It is hard to set the deck angle at one time ,it needs the operation personnel adjusting several times according to the flow of the mud .The best pool configuration is when the mud covers the first and second shaker screen.

Drill cuttings separation

Drill cuttings are separated by shale shaker, decander, desiler, decanter centrifuge, and collected by screw conveyor or vacuum unit , for further separation of vertical cutting dryer & decanter centrifuge.

In an ideal situation, all drill solids are removed from a drilling fluid by solids control equipment on a drilling operation. The two primary sources of solids are chemical additives and formation drill cuttings. Drill cuttings are contaminants that degrade the performance of the drilling fluid. If the drill cuttings are not separated, they will be ground into smaller and smaller particles that become more difficult to remove from the drilling fluid.

Most formation solids can be removed by mechanical means at the surface. Small particles are more difficult to remove and have a greater effect on drilling fluid properties than large particles. The particle size of drilled solids incorporated into drilling fluid can range from 1 to 250 microns (1 micron equals 1/25, 400 of an inch of 1/1000 of a millimetre).

Mud mixing and agitation equipments

Whatever the drilling is, if only there is mud system, you will have mud mixing and agitation issues after a period of drilling.

Mud mixing equipment

GN jet mud mixer is specially used for mud mixing. GN Jet mud mixer is composed of a venturi type hopper and a centrifugal pump, we have 4 models available, GNSL150-45S,GNSL150-35S, GNSL100-25S,GNSL100-25M with 1320gallons/min, 880gpm, 400gpm and 264gpm mixing capacity.

How a venturi hopper work?

The fluid velocity must increase through the constriction to satisfy the equation of continuity, while its pressure must decrease due to conservation of energy: the gain in kinetic energy is balanced by a drop in pressure or a pressure gradient force. An equation for the drop in pressure due to the Venturi effect may be derived from a combination of Bernoulli’s principle and the equation of continuity.
Mud agitation equipments

Mud agitator is mainly used for mud agitation, sometimes for mud mixing. Also in some applications, vacuum degasser also be called a” big mud agitation equipment”.Mud agitator is composed of electric motor and gear box, the popular connection method is direct connection, in some countries, they still use shaft connection mud agitator.
