摘要： A three-phase centrifugal separator for a mixture which may include oil, water, gas and/or solids. A rotor is provided with an inner rotor chamber encircled by an outer rotor chamber, the mixture being delivered to the inner rotor chamber wherein it is centrifugally separated into an inner gas phase encircling the rotor axis, an annular intermediate oil phase encircling the gas phase, and an annular outer water and solids phase encircling the oil phase. Water and solids are discharged into the outer rotor chamber through discharge ports in the periphery of the inner rotor chamber, and are subsequently discharged into an enclosing housing means through discharge ports in the periphery of the outer rotor chamber. A water supply means delivers water to the outer rotor chamber at a rate at least equal to, and preferably considerably in excess of, the discharge capacity of the discharge ports in the outer rotor chamber at a given rotor speed so as to maintain a substantially constant pressure in the outer rotor chamber at such rotor speed. Means are provided for removing oil and gas from the corresponding phases in the inner rotor chamber.

摘要： This pitot pump is provided with pressure balancing for minimizing thrust loads on its bearings. The pump has a housing containing a rotatable casing mounted on a shaft. A fixed pitot tube is mounted in the casing for withdrawing pressurized fluid as the casing rotates and discharging the fluid through an axial outlet passage extending through one end wall of the casing. Fluid is introduced to the casing through the same end wall by way of an annular inlet passage coaxial with the outlet passage. The fluid flows from this inlet passage to the interior of the casing through a plurality of radiating passages in the end wall of the casing. When such a pump is used with a pressurized inlet fluid, an axial thrust on the casing bearings would result if it were not for the thrust balancing means. This comprises an axial balancing chamber between a portion of the end wall opposite the fluid inlet and a portion of the pitot tube. The interior of this chamber is in fluid communication with the suction inlet of a jet pump. Pressurized fluid from the pitot pump is applied to the jet inlet of the jet pump and the outlet of the jet pump is connected to the inlet to the pitot pump. Thus, pressure in the balancing chamber is reduced for minimizing axial thrust and any fluid entering the chamber from the interior of the casing is repressurized and returned to the pitot pump inlet.
摘要翻译：该皮托泵配有压力平衡，用于最小化其轴承上的推力载荷。泵具有容纳安装在轴上的可旋转壳体的壳体。固定的皮托管安装在壳体中，用于在壳体旋转时抽出加压流体，并通过延伸穿过壳体的一个端壁的轴向出口通道排出流体。通过与出口通道同轴的环形入口通道，流体通过同一端壁引入壳体。流体通过壳体端壁中的多个散热通道从该入口通道流到壳体的内部。当这种泵与加压入口流体一起使用时，如果不是用于推力平衡装置，则会导致套管轴承上的轴向推力。这包括在端壁的与流体入口相对的部分和皮托管的一部分之间的轴向平衡室。该室的内部与喷射泵的吸入口流体连通。来自皮托托泵的加压流体被施加到喷射泵的喷射入口，并且喷射泵的出口连接到皮托泵的入口。因此，减小平衡室中的压力以最小化轴向推力，并且从壳体内部进入腔室的任何流体被再加压并返回皮托泵入口。

摘要： an oil well completion comprising a well bore drilled from the surface through and below an oil producing formation to provide an extension below the producing formation, a jet pump in the extension below and in communication with the producing formation, means for conducting power fluid under pressure downwardly in the well bore from the surface to the jet pump, and means for conducting spent power fluid, and fluid from said producing formation discharged by said jet pump, upwardly in the well bore from the jet pump to the surface. The purpose of locating the jet pump in a downward extension of the well bore below the producing formation is to provide sufficient submergence of the jet pump to avoid cavitation, without curtailing the flow of fluid from the producing formation into the well bore.

摘要： A jet pump has a nozzle for a power fluid, a Venturi for the power fluid and a well fluid, and a passage for the well fluid radially outside the Venturi and into the discharge of the nozzle. The power fluid aspirates the well fluid and the combined stream enters the Venturi. The Venturi is ceramic for erosion control. A shell sheaths the ceramic throughout its length and loads the ceramic compressively to provide a compressive preload on it. This preload opposes radial, outward acting stress in the Venturi arising from a greater fluid pressure within the Venturi than the fluid pressure outside it. The preload also produces a friction lock to keep the Venturi from sliding out of the shell because of an axial pressure differential.
摘要翻译：喷射泵具有用于动力流体的喷嘴，用于动力流体的文丘里管和井流体，以及用于径流在文丘里管外部并且进入喷嘴排出口的井流体通道。动力流体吸出井液，组合流进入文丘里管。文丘里管是用于侵蚀控制的陶瓷。壳体在其整个长度上覆盖陶瓷，并对陶瓷进行压缩加载以在其上提供压缩预载荷。这种预载荷反映了文丘里管内的径向，向外作用的压力，这是因为文丘里管内的流体压力比其外部的流体压力更大。预压也产生摩擦锁，以保持文丘里管由于轴向压差而从外壳滑出。
