泥浆振动筛及使用其分离含有固体的钻井流体的方法
Abstract:
本发明公开了泥浆振动筛和用于使用泥浆振动筛分离含有固体的钻井流体的方法，所述泥浆振动筛包括基座(D)、与所述基座(D)隔开的筛篮(100)，所述筛篮(100)包括具有粗筛网(115)的粗筛板(111)、具有筛网组件(122a，122b)的上筛板(112)和具有细筛网组件(125a，125b)的下筛板(113)，所述上筛板(112)具有进给端和固体排出端，在所述上筛板(112)的所述排出端处布置在所述筛篮(100)中的输送槽(151)和分流器板(151)，所述方法包括以下步骤：使含有固体的钻井泥浆流动到所述粗筛网(115)上，大固体越过所述粗筛网(115)，含有固体的钻井流体通过所述粗筛板(111)到达所述上筛板(112)的筛网组件(122a，122b)，筛选出的固体越过所述筛网组件(122a，122b)进入所述输送槽(151)中，其由所述分流器板(151)引导。
Abstract(English):

The present invention discloses a shale shaker and a method for separating drilling fluid containing solid by using the same. The shale shaker comprises a base (D), a screen basket (100) separated from the base (D). The screen basket (100) includes a wide-meshed screen board (111) with a wide-meshed screen (115), an upper screen board (112) having screen assemblies (122a, 122b), and a lower screen board (113) having screen assemblies (125a, 125b). The upper screen board (112) has a feeding end and a solid discharge end, wherein the discharge end of the upper screen board (112) is provided with a conveyor trough (151) and a shunt board (151) in the screen basket (100). The method provided by the invention comprises the following steps: flowing the drilling fluid containing solid to the wide-meshed screen (115), allowing big solids to cross the wide-meshed screen (115), passing the drilling fluid containing solid through the wide-meshed screen board (111) to reach the screen assemblies (122a, 122b) on the upper screen board (112), screening the solids to cross the screen assemblies (122a, 122b), and performing the solids to enter into the conveyor trough (151) through the guiding of the shunt board (151).
