Abstract
High loss of energy is a common problem in all oil fields. It is mainly cau sed by the intrinsic disadvantage of traditional beam-pumping units, such a s complex transmission devices, short stroke, low efficiency, etc. The aim of this paper is to apply Electromagnetic Launch technology in oil-pumping unit. Both Electromagnetic Launch technology and Linear Motor technology ar e combined to develop a novel direct-driven Electromagnetic pumping unit (E MPU) in which each coil is driven and controlled separately. The principles and working process of the electromagnetic pumping unit are described, Wit h the conditions of work environment being taken into consideration, experi ments were conducted to test and verify the performance of the model protot ype. The disadvantages of a traditional oil-pumping unit are overcame by th e novel linear electromagnetic pumping unit.
