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.

摘要： Techniques and apparatus are provided for improved diagnostics of downhole dynamometer data for control and troubleshooting of reciprocating rod lift systems. A method for pump fillage determination for a reciprocating rod lift system is provided. The method generally includes measuring downhole data during a pump cycle, wherein the downhole data comprises a first plurality of data points associated with an upstroke of the pump cycle and a second plurality of data points associated with a downstroke of the pump cycle, each data point comprising a rod position value and an associated rod load value; converting the data points to non-dimensional data points, calculating non-dimensional slope values between non-dimensional data points; and determining pump fillage based, at least part, on the calculated non-dimensional slope values.

摘要： A pump drive assembly (10) including a driver (18), a pump drive member (36) driven by the driver (18), and a decoupler (20a) that decouples the drive member (36) from the driver (18) when a force acting upon the drive member (36) exceeds a threshold force. The pump drive member (36) can be a piston rod (36), and the decoupler (20a) can be a magnet (20a) attached to the piston rod (36) and coupled to a magnetically attracted plate (22) driven by the driver (18). When a force resisting movement of the piston rod (36) exceeds the magnetic force coupling the magnet (20a) to the plate (24), the magnet (20a) decouples from the plate (24), and the pumping operation ceases.
