适用山地地区的水力提升动力机组的研制

摘要

现国内在川渝地区发现大量油气田，储藏量巨大。 川渝地区压裂现场多数在大山深处，井场范围有限，蓄水池距水源井有一定的高度差，川渝地区地形和地质情况复杂，连续的长输水管道，复杂多变的沿势地形，对于水力输送有着巨大的挑战。研制的水力提升动力机组，满足了川渝页岩气项目大排量、高扬程泵水的要求，实现了机组远程自动控制和实时监控，实现机组本地无人值守，具备便于管理、运作高效、操作便捷、安全可靠等特性。该水力提升动力机组采用撬装结构，使用方便，便于运输和安装。通过对机组连接管汇进行优化设计，很好的解决了管汇和输水管道内剩水问题。样机进行了现场试验，试验过程中样机运行平稳，工作效果良好，各项性能指标完全达到设计要求。

Abstract

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.
