Performance of Linear Motor Pumping Unit and Beam Pumping Unit

The traditional petroleum engineering run by "engine,rod,pump" is restricted to the pump unit structure and operating rules,leading to several poor effects such as short stroke,heavy dynamic load and low efficiency of deep swabbing.The successful development of linear motor unit eliminated the phenomenon of "Great Horse Pulling Cart" and realizes long stroke,slow speed and pumping parameter adjustable at no stage.The study of the work performance of linear motor unit and the influence on pumping system was discussed,which provides theoretical support for the pumping equipment optimization comparing with beam pumping unit.
