The invention relates to the technical field of the oil extraction project, and particularly belongs to a double-well mutually balanced type direct drive oil pumping machine control system and an oilpumping device used in the oil field. The problems that a tower type direct drive oil pumping machine is complex in structure, short in integral service life and poor in safety, an oil pumping machinefoundation needs to be prefabricated, and reverse power generation cannot be effectively utilized are solved. The oil pumping device is composed of one direct drive oil pumping machine control system(1) and two direct drive oil pumping machines (2). The double-well mutually balanced type direct drive oil pumping machine control system and the oil pumping device have the advantages that the structure is simple, few transmission components are adopted, transportation and installation are easy, oil pumping machine foundation prefabrication is not needed, the reverse power generation in the oilpumping machine running process can be effectively utilized, the running life of the system can be prolonged, energy consumption is reduced, equipment reliability is high, and the running cost is low.
