    • A solids separation system may be used to separate solids, such as cuttings from drilling fluids used in well drilling operations. The system includes a settling tank having transverse baffles defining a fluid receiving chamber, a fluid output chamber and one or more intermediate chambers. Fluid introduced into the fluid receiving chamber can flow in a sinuous path through apertures in the baffles to the fluid output chamber. Solids settle to the bottom of the settling tank. A material conveyor, preferably an auger, extends along a bottom surface of the settling tank to an outlet port in the fluid receiving chamber. A centrifuge is connected to the output port to receive fluid in which solids have been concentrated. Fluid output from the centrifuge is reintroduced into the settling tank. The apparatus and method of the invention permit a single centrifuge to be used to handle a higher volume of fluid than is possible with conventional methods and apparatus. This provides significant cost savings.
    • 固体分离系统可用于分离固体,例如钻井操作中使用的钻井液的切屑。 该系统包括具有限定流体接收室的横向挡板的沉降槽,流体输出室和一个或多个中间室。 引入流体接收室的流体可以以弯曲的方式流过通过挡板中的孔到流体输出室。 固体沉降到沉淀池的底部。 材料输送机,优选螺旋钻,沿沉降槽的底表面延伸到流体接收室中的出口。 离心机连接到输出端口以接收其中固体已经集中的流体。 来自离心机的流体输出被重新引入沉淀槽。 本发明的装置和方法允许使用单个离心机来处理比常规方法和装置可能的更高体积的流体。 这显着节省了成本。
