Abstract: The relay lift technology of hydraulic jet pump and sucker rod pump has been studied.The principle of the technology is that the cashing reverse circulation jet pump lifts well fluid from the oil reservoir to some height where the sucker rod pump lifts the fluid to the ground contimuously.The methods of technology design, jet pump parameter matching design and association design of the two pumps are described in this paper.The technology was tested by Zhuang 52-10 well in Shengli Oilfield.The set depths of the sucker rod pump and the jet pump are 1650m, 2250m respectively, and relay lift height is 600m.As a result, the difference between the maximum and minimum beam unit load is smaller than before, and the maximum beam unit load is reduced greatly, and daily oil production of the well increased.The test indicates that the relay lift technology can improve the test indicates that the relay lift technology cam improve the working conditions of the swabbing system and effectively increased.
