Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since drilling fluids solids control is vital in keeping down costs associated with the drilling fluid. The basic design consists of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shakes or vibrates the drill cuttings, commonly shale shaker, across and off of the screens as the drilling fluid flows through them and back into the drilling fluids processing system, often called a drilling mud system. This separates the drill cuttings, often called solids, from the drilling fluid so that it can be recirculated back down the well bore.In oilfield industry, linear motion shale shaker are widely used for drilling mud solids control of oil gas well drilling for rig.
The use of oilfield shale shaker
1,Adjust the specification of screens with the variation of the lithology, drilling rate, well depth and the type of drilling fluid. Choosing the effective screens with fine mesh as far as possible.
2,The flow area should cover from 75 to 80 percent of the total screen area at the normal drilling rate.
3,The drilling fluids pumped out of wellbore should be treated by drilling fluids shale shaker as the primary purification process, and keep 100 percent utilization of shale shaker.
Use and working principle
1. The shale shaker is the first level in drilling mud solid phase control system, dispose the mud which carrying large drilling cuttings returned from the well and enter into the second separation equipment.
2.The shale shaker is designed according to the linear motion locus produced by screen surface.
