3, diagnostic inefficient wells. Diagnosis method is to determine the overall efficiency of pumping system, but simply determine the overall efficiency of the original motivation for measuring input power, measured bottomhole producing pressure and accurate production of test data. General beam pumping system should be the overall efficiency of about 50% if less than this should improve its performance. Improve the overall efficiency of the technology, including maintaining a high volumetric efficiency (the pump shaft into the specification and the amount of matching, to eliminate disturbance, with taking the time to control or timer control pumping), and replace the motor too much.
