    • A centrifugal submersible pump has wear resistant features to resist erosion due to sand laden fluid from a well. The pump has diffusers and impellers located within the housing. Each diffuser has a diffuser sleeve with a coaxial bore. The diffuser sleeve is of a material harder than the remaining portions of the sleeve. A hardened lower hub locates slidingly within each diffuser sleeve. The lower hub rotates with the shaft. Each impeller has an upper hub that locates above the lower hub and is also carried by the shaft for rotation with the shaft. The upper hub extends into the bore of the next upward diffuser sleeve. The lower hub is of a material harder than the upper hub and the vane section of the impeller.
    • 离心式潜水泵具有耐磨特性,可以防止由于来自井的含沙液体而导致的侵蚀。 泵具有位于壳体内的扩散器和叶轮。 每个扩散器具有带同轴孔的扩散器套筒。 扩散器套筒是比套筒的其余部分硬的材料。 硬化的下毂在每个扩散器套筒内滑动定位。 下轮毂与轴一起旋转。 每个叶轮具有位于下轮毂上方的上轮毂,并且还包括轴,用于与轴一起旋转。 上部轮毂延伸到下一个向上扩散器套筒的孔中。 下轮毂是比上轮毂和叶轮的叶片部分更硬的材料。

    • The motor cooling and protection system has a shroud concentrically disposed about a motor housing of a downhole motor. The shroud is sealed from well fluids in the well and defines and annular chamber between the motor housing and the shroud. A longitudinal annular baffle is located in the chamber and partitions the chamber into two annular and concentric sub-chambers. The two sub-chambers have axially spaced apart communication openings such that the two sub-chambers are in fluid communication with each other. A cooling fluid having high conductive heat transfer rates is located in the chamber for circulating between the two sub-chambers, through the communication openings, to facilitate and enhance the transfer of heat between the motor and the well fluids.
    • 电动机冷却和保护系统具有围绕井下电动机的电动机壳体同心设置的护罩。 护罩与井中的井液密封,并在电动机壳体和护罩之间限定和环形室。 纵向环形挡板位于腔室中,并将腔室分隔成两个环形和同心的子腔室。 两个子室具有轴向间隔开的连通开口,使得两个子室彼此流体连通。 具有高导电传热速率的冷却流体位于室中,用于通过连通开口在两个子室之间循环,以促进和增强电动机和井流体之间的热传递。

    • A submersible pumping system for use downhole, wherein the system includes a pump, an inlet section for receiving fluid, a pump motor, and a viscometer. Pumping system operating parameters are adjusted based on wellbore fluid viscosity measured by the viscometer. The viscometer can be disposed deep in the wellbore, adjacent the pump, seal, motor, at the pump intake or anywhere on the pumping system. The viscometer may be connected to a control system for controlling the pumping system in response to viscosity measurement and may include a sonic viscometer. A method of operating a downhole submersible pumping system is included that measures fluid viscosity in the wellbore during production operations. Pumping parameters can be adjusted based on the measured viscosity.
    • 一种用于井下的潜水泵送系统,其中系统包括泵,用于接收流体的入口部分,泵马达和粘度计。 泵系统运行参数根据粘度计测量的井筒流体粘度进行调整。 粘度计可以设置在井眼深处,靠近泵,密封件,电机,泵入口处或泵送系统上的任何位置。 粘度计可以连接到用于响应于粘度测量来控制泵送系统的控制系统,并且可以包括声波粘度计。 包括操作井下潜水泵送系统的方法,其在生产操作期间测量井眼中的流体粘度。 泵送参数可以根据测量的粘度进行调整。
