In order to make fully use of frequency conversion technology in the pumping unit energy conservation, promote conversion technology application in the oilfield. In this paper, the advantages of frequency conversion technology in energy -efficient pumping unit and the limitations of some common oilfield energy conservation methods are discussed. With AC variable speed theory, some shortcomings of frequency conversion technology applications are pointed out. Finally, a reasonable and reliable pumping unit frequency conversion energy conservation technology is proposed. Through theoretical analysis and onsite tests, the technology can effectively overcome the defects of frequency conversion technology applications.
