| 摘要 | A gas tight shale shaker for enhanced drilling fluid recovery and drilled solids washing. A process and apparatus for liquid phase-solid phase separation of oil base drilling mud-containing drill cuttings is described including flowing the drilling mud-containing drill cuttings over a vibrating screen bed to cause a least a portion of the drilling mud to pass through the screen bed and the drill cuttings to remain on the screen bed. A diluent is added to the oil base drilling mud containing drill cuttings prior to flowing the drilling mud containing drill cutting over the screen bed. The entire process is performed in a gas-tight environment preventing escape of diluent from the process into the external atmosphere and preventing introduction of gases into the process from the external atmosphere. | ||||||
