    • A fluid recovery system for producing subsurface oil and water deposits comprises a high capacity pump such as a high capacity centrifugal pump (12) that is immersed within the deposit, a well casing (23) that extends into the deposit from the surface, a source of rotary motion power (14), and a power transmission system (25) that connects the power source (14) and the pump (12) in the well casing (23). The power transmission system (25) includes a step up transmission (47) and a rod string (21) which interconnects the power source (14) and the transmission (25) to deliver rotary motion to the transmission (25). The pump (12) is connected to the transmission (25) for delivery of higher speed rotary power to the pump (12).
    • 用于产生地下油和水沉积物的流体回收系统包括高容量泵,例如浸入沉积物中的高容量离心泵(12),从表面延伸到沉积物中的井套管(23) 的旋转动力(14)的动力传递系统(25),以及将所述动力源(14)和所述泵(12)连接在所述井壳体(23)内的动力传递系统(25)。 动力传递系统(25)包括升降变速器(47)和连接电源(14)和变速器(25)的杆串(21),以将旋转运动传递到变速器(25)。 泵(12)连接到变速器(25),用于将高速旋转动力输送到泵(12)。
