Overview of shale shaker in drilling mud system

A shale shaker can be used in all drilling applications where fluid is used as the drilling mud .Screen selection is controlled by the circulation rate, shaker design, and drilling mud properties. Screen selection for shale shakers is also dependent on geographical and geological location. Shaker screen combinations that will handle specific flow rates in the Middle East, for example, will not necessarily handle the same flow rates in Russia.

Shale shakers can be divided into linear motion shale shaker and ellipse & round motion shaker, basing on the difference of their screen basket moving tracks. As the most important equipment in solids control system, shale shakers are widely used in almost all kinds of drilling rig, and they take an important part in drilling fluids cost as well as total drilling drilling cost. So it is necessary to choose right type of linear motion shale shaker according to the viscosity of drilling fluids & solids density.

Drilling fluids shale shakers are generally consist of skid, vibration isolation member, screen, screen basket, back tank ( or called mud feeder), vibration motor, etc. no matter it is linear motion shale shaker, or ellipse shaker. The drilling fluids flows directly into the back tank through the flow line after the mud comes out of the surface of the well. The solids that precipitates in the back tank would be discharged through the bottom hole, and drilling fluids would flow onto the screen surface. The solids that are bigger than the meshes would be separated and threw out of the shale shaker through other end of shale shaker screen. and the fluids with smaller particles would go through the meshes and enter the mud tank for further separation.

As a key part, screens are utilized in linear motion shale shaker, desander, desilter, high efficient mud cleaner to take away the solids inside the drilling fluids. Countless corporations who cope with solids deal with gear invest substantially income and personnel in development of shaker screen technologies, which incorporate Brandt, KOSUN, and so on.
