A method and apparatus for separating solids from drilling fluid returning from a drilling operation wherein the apparatus comprises a separation tank divided into first and second compartments each of downwardly diminishing cross-sectional areas. There are continuous solid removal means at the bottom of each compartment. The drilling fluid is passed through a shale shaker and deposited in the first compartment where a portion of the solids settle and are removed by a clean out auger. The drilling fluid is skimmed from the first compartment and transferred to the second compartment where more solids settle and are removed. The drilling fluid then is passed through a plate separator comprising a plurality of horizontally stacked and spaced bidirectionally corrugated plates. Solids removed by the plate separator is returned to the second compartment while the remaining drilling fluid is collected and returned to the drilling operation. Flow of the drilling fluid through the apparatus is gravity-driven.

Méthode et appareil de séparation de solides des fluides provenant d'opérations de forage. L'appareil comprend un réservoir de séparation divisé en un premier et un second compartiments dont la surface de section transversale va en diminuant vers le bas. Un dispositif d'élimination en continu des solides se trouve dans la partie inférieure de chaque compartiment. Le fluide de forage passe à travers un tamis vibrant puis une partie des solides se dépose dans le premier compartiment où ils sont enlevés par une vis sans fin de nettoyage. Le fluide de forage du premier compartiment est écumé puis transféré dans le deuxième compartiment où il y a précipitation d'autres solides qui sont eux aussi enlevés. Le fluide de forage passe ensuite dans un séparateur à plaques constitué d'une pluralité de tôles ondulées empilées horizontalement et espacées bidirectionnellement. Les solides récupérés par le séparateur à plaques sont renvoyés dans le deuxième compartiment tandis que le fluide de forage restant est recueilli et renvoyé aux activités de forage. L'écoulement du fluide de forage dans l'appareil se fait par gravité.
