    Abstract: 对具有设置在偏斜的井筒中的井下泵的泵设备进行诊断通过两个耦合的四阶非线性微分方程表征杆柱的轴向位移和横向位移，该两个耦合的四阶非线性微分方程包括轴向运动方程和横向运动方程。为了解该方程，导数被有限差分模拟所替代。杆柱的初始轴向位移通过假定不存在横向位移并解轴向方程而计算得出。初始轴向力通过使用初始轴向位移并假定不存在横向位移而计算得出。初始横向位移通过使用初始轴向力和初始轴向位移而计算得出。轴向力和摩擦力通过使用初始位移而计算得出，并且井下泵处的轴向位移通过用轴向力和摩擦力解轴向方程而计算得出。计算井下泵处的载荷从而可以生成井下卡。

    Abstract: Diagnosing a pump apparatus having a downhole pump disposed in a deviated wellbore characterizes axial and transverse displacement of a rod string with two coupled non-linear differential equations of fourth order, which include axial and transverse equations of motion. To solve the equations, derivatives are replaced with finite difference analogs. Initial axial displacement of the rod string is calculated by assuming there is no transverse displacement and solving the axial equation. Initial axial force is calculated using the initial axial displacement and assuming there is no transverse displacement. Initial transverse displacement is calculated using the initial axial force and the initial axial displacement. Axial force and friction force are calculated using the initial displacements, and the axial displacement at the downhole pump is calculated by solving the axial equation with the axial force and the friction force. Load at the downhole pump is calculated so a downhole card can be generated.

    Abstract: A walking beam pumping system is disclosed wherein the pumping system's prime mover is gravity. In one embodiment, the system comprises a walking beam pivotally coupled to a support structure at a pivot point substantially central along the length of the walking beam. A counterbalance weight is disposed along the length of the walking beam. A position device is provided for moving the counterbalance weight along at least a portion of the length of the walking beam. As the counterbalance weight moves along the length of the walking beam, the beam's center of gravity is modulated. By modulating the position of the counterbalance weight in an appropriate manner, the walking beam is caused to pivot back and forth with respect to the support structure. A pumping assembly, for example a sucker rod string, is attached to one end of the walking beam, such that as the walking beam pivots back and forth, the pumping system is actuated to pump fluid out of, for example, an oil well bore. In one embodiment, the positioning device for moving the counterbalance weight comprises a linear motor.
