    • A hydraulic choke for a flow stream from a well with large diameter particulate matter of a finite amount includes an inlet with a defined inlet flow area and a chamber with a defined chamber flow area. The inlet flow area is about ⅓ the size of the chamber flow area. The choke further includes a gate in the chamber surrounded by a housing separated from the chamber wall, a piston for engaging the gate against a seat, a studded outlet in communication with the chamber in the same plane as the inlet, and a studded solids removal outlet in communication with the chamber. The studded solids removal outlet is oriented approximately 90 degrees from the inlet position to permit the large diameter particulate matter to fall from the flow stream and into a solids receptacle for collecting the large diameter particulates matter. The solids receptacle is in communication with the studded solids removal outlet.
    • 用于来自具有有限量的大直径颗粒物质的井的流动的液压扼流圈包括具有限定的入口流动面积的入口和具有限定的室流动面积的室。 入口流动面积约为室流动面积的1/3。 所述扼流器还包括在所述腔室中的门,所述门由与所述腔室壁分离的壳体围绕,用于将所述门接合到座椅的活塞,与所述腔室在与所述入口相同的平面中连通的镶嵌出口,以及镶嵌的固体去除 出口与室连通。 镶嵌的固体除去出口从入口位置定向成大约90度,以允许大直径的颗粒物质从流动流中落入固体容器中,用于收集大直径的颗粒物质。 固体容器与分散的固体去除出口连通。
