Take Care of Shaker Screen to Improve Shaker Performance

The shale shaker is the first phase solids control equipment in mud circulation system. It is of vital importance to the downstream solids control efficiency, if for instant, the large solids are not properly removed by the shaker screens, it will give much burden to the desander, desiter and even do damage to the decanter centrifuge. Therefore, shaker screening performance should be increased by many ways, among which the shale shaker screen is the key factor.
If not specific drilling fluids is required by certain drilling formation, use the finest screens as possible without incurring mud carryover and the shaker to be configured in a optimum set-up condition such as deck angle, pool depth etc.
