A large number of oil and gas fields have been discovered in the Sichuan Chongqing region in China, with huge reserves. Most of the fracturing sites in the Sichuan Chongqing region are located deep in the mountains, with limited well site coverage and a certain height difference between the reservoir and the water source well. The terrain and geological conditions in the Sichuan Chongqing region are complex, with continuous long water pipelines and complex and variable terrain along the terrain, posing great challenges to hydraulic transportation. The developed hydraulic lifting power unit meets the requirements of the Sichuan Chongqing shale gas project for large displacement and high head pumping, realizes remote automatic control and real-time monitoring of the unit, and realizes local unmanned operation of the unit. It has the characteristics of easy management, efficient operation, convenient operation, safety and reliability. The hydraulic lifting power unit adopts a pry mounted structure, which is convenient to use and easy to transport and install. By optimizing the design of the unit connection manifold, the problem of residual water in the manifold and water transmission pipeline has been effectively solved. The prototype underwent on-site testing, and during the testing process, it ran smoothly with good working results, and all performance indicators fully met the design requirements.
