Analysis of experimental simulation of the well sucker rod pump

Authors: M.E. Rozhkin (Ukhta State Technical University)

The results of experimental simulation of the well sucker rod pump with a specially designed stand are analyzed. It is shown, that the delivery rate with the gas concentration increase at the pump intake decreases nonlinearly. It is established, that with the rod travel velocity increase the coefficient of bucket rods elastic extensions decreases. High reliability of evaluation of the actual well production, the capability of the pump fault diagnosis with a high degree of accuracy are shown experimentally. The dynamometer card form change depending on the gas content in the pump intake is revealed.
