The type of drilling mud shale shaker

As the first stage of solid control system, the shale shakers are the primary means of cuttings removal, and the proper configuration of the shale shakers has been proved vital to the drilling of the well. During the operation, the operator should be constantly aware of any losses occurs over the shale shakers and make some change if necessary. Drilled solids are by far the main cause of the drilling fluids being contaminated and the shale shaker is the main means of preventing this from happening,

Before dilling mud circulating begin, the driller should decides what size of shale shaker screens should be chose. Usually, the shale shaker has been installed with double-deck screens, the upper and the lower screens. The figure for mech size is the number of wires per inch--the higher the value, the smaller the openings.The choice of shale shaker is largely depended on the flow rates, the cutting size, viscosity.If the mesh is too coarse, the solids will simply pass through the screen back into the circulating system. If the shale shaker screens are too fine, none of the solids will pass through and will be prompting large mud losses, but if the operators adopt a screen with the same size mesh as the cuttings that are coming to the shale shaker, then the screen will be “blinded” and the efficiency will drop dramatically, as the individual particles stock themselves on the mesh.

The type of drilling shale shaker

Usually, there are two common used shale shakers, linear motion shale shaker and balanced elliptical motion. KOSUN linear motion shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells. While, KOSUN elliptical motion shale shaker in balanced elliptical mode is especially effective while drilling top-hole sections where heavy, high-volume solids usually are encountered. In these intervals, shakers need to generate high G-forces to effectively move dense solids across the screens. During drilling breaks and increased viscosity the balanced elliptical motion eliminates the need for screens changes as well as losses.
