Abstract

The article gives an overview of modern methods for monitoring the operation of a sucker rod pump with a pumping jack to identify various equipment failures, among which the two possible ones are determined: the dynamometric method and the diagnostic method based on the analysis of active power diagrams (wattmetering). With the help of the dynamometric method, it is possible to identify 3 groups of failures in the operation of the sucker rod pumping unit: leakage of liquid from tubing and valves; mechanical failures; failures connected with pumping a well fluid with various impurities, i.e. control of submersible equipment. The most informative method for the ground equipment monitoring is the wattmetering method. With this method, it is possible to analyze the operation of an electric drive: current overload, voltage deviation, phase distortion, a frequency deviation of the supply voltage, determination of the harmonic ratio for the supply voltage, determination of the power factor, etc. In addition, with the help of wattmeters it is possible to detect characteristic faults in the mechanical part of the pumping jack: breakage and slippage of belts, breakage of rods, slapping in a reducer, misbalance of counterweights and some abnormal operating modes of submersible pumping equipment: pump jamming, high or low plunger fit; faulty valves; low operating efficiency of pump, etc.
