How to deal with drilling fluid shaker screen slurry leakage
2025-12-25This phenomenon is primarily related to factors such as the high solids content in the drilling fluid, high mud viscosity, and dispersed drill cuttings. It is also related to the inherent characteristics of the shaker screen, such as low vibration force, high mesh count, and small screen area. It is also significantly affected by the direction and location of the shaker screen's inlet during on-site installation. This can be a...
