Abstract

To date, there are more than 60000 wells in Daqing Oilfield including injectors and producers. The annual investment is 1.07 billion RMB in the maintenance of artificial lift equipment, which is a heavy burden for the sustainable development of Daqing Oilfield. After years of study, a series of repairing techniques for artificial lift equipment have been created, which saved 0.5 billion RMB per year, leading to remarkable benefits and efficiency as well.This paper first presents the background of artificial lift equipment repairing technique in Daqing Oilfield. Then, a detailed introduction is given about the development history and current situation of key repairing technology, including the oil tube, rod string, and suck-rod pump. With reference to the study result in automobile and military territory remanufacturing technology, this paper analyzes the situation of artificial lift repairing techniques and evaluates the development direction and tendency of this field for a mature oilfield in the future.
