BEAM PUMPING UNIT FOR INCLINED WELLHEAD

机译:斜井口光束抽油机

摘要

A method and pumping unit for use with an inclined wellhead. Proper address of the wellhead is accomplished through incorporation of an elbow-shaped walking beam. The forward section of the walking beam is fabricated such that its longitudinal axis is angled to address the inclination of the wellhead. The rearward section of the walking beam and the four-bar linkage system remains unchanged relative to a prior art pump jack intended for vertical wells. This modification is a simple and effective means of addressing an angled wellhead while preserving the well-known operating characteristics of a prior art pumping unit. Torque factors, polished rod position, speed, acceleration, stroke length, and effective counterbalance remain unchanged.
