Abstract: Traditionally, artificial pitching was used for paraffin removal of oil wells. However, it is complicated. The automatic pitching device based on alternating motion of double piston was designed by electromechanical integration technologies. The device could remove paraffin by pitching automatically and regularly. The device has advantages such as high integration, compact conformation, pressure relief without venting and heat tracing in winter. Moreover, it solves the bottleneck of oil leakage in ball storage tank and fills up domestic blank of automatic pitching. It is shown that the device has a stable performance and is able to meet the demands of digital management with unattended oil production status when put into operation with 100% of pitching accuracy rate and 99% of defect-free rate. Its wide applications reduced operation cost and improved production efficiency. Now, it has become one of he key technologies of digital management in Changqing Oilfield.

Key words: automatic pitching, paraffin removal, oil pipeline, digitalization
