    摘要： 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.

    摘要： A method and system for determining the pump fillage of a sucker rod pumping system using torque feedback when pumping wellbore fluids from the particular well on which the sucker rod pumping system is installed. During the pump stroke, a microprocessor samples torque of the pump's mechanical system at an associated horsehead position at regular intervals and once the stroke is completed the raw torque samples and associated horsehead positions are placed in an array, the array of raw torque samples and horsehead positions can be filtered by the microprocessor into a second filtered array and then converted by the microprocessor into a rotatum array (derivative of torque with respect to time) of one or both of the raw or filtered arrays and stored as a rotatum array. The down stroke portion of the rotatum array is then analyzed by the microprocessor to determine the horsehead position when the piston of the down hole pump encounters wellbore fluid in the well (pump fillage). The microprocessor, based on the determined pump fillage, adjusts the speed of the pumping system to maintain an optimal pump fillage determined to be the most economical for the particular well on which the sucker rod pumping system is installed.

    摘要： 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.
