Optimal Control and Strategy of Operating Mechanism for Pumping Unit Intermittent Pumping

摘要

In this work a new perspective of pumping unit intermittent pumping intelligent control in strippers is presented. The strategy consists in associating economic situations and dynamometer cards analysis in a cascaded control. In the proposal, the widely applied control strategies based on dynamometer cards and downhole pressure modeling and the overall economic efficiency, since the development of pumping unit operation mechanism plays a vital role to ensure energy saving in low-volume wells. The simulation results are analyzed in order to evaluate the operational conditions propitiated by intermittent pumping control in actual operation.
