川渝地区页岩气压裂设备发展新方向

New Development Direction of Shale Gas Fracturing Equipment in Sichuan-Chongqing Area

随着非常规油气超深井和长水平井数量的不断增加,油气开采的储层改造技术也在持续跟进,进而促进了压裂作业设备朝着大功率、高负荷、连续工作及智能化等方向发展。川渝区块是我国“十四五”页岩气开发的主战场,在介绍传统压裂设备作业现状的基础上,分析了其在川渝地区页岩气压裂作业中存在的短板,指出了压裂设备将朝着电驱压裂设备、涡轮压裂设备方向发展;就压裂机组故障状态监测与故障诊断系统、压裂储能(变电)系统技术及低压一体化物联系统等技术在压裂设备中的应用进行了展望,进而指出我国压裂技术装备的发展方向,即朝着环境优化型、轻量化、自动化发展。所得结论可为我国川渝页岩气的高效开发及压裂设备的现场应用和优化提供参考。

As the number of ultra-deep and long horizontal wells of unconventional oil and gas continuously increase,the reservoir reconstruction technology for oil and gas exploitation is also continuing to follow up,thus promoting the development of fracturing equipment in the direction of high power,high load,continuous operation and intelligence.Sichuan-Chongqing block is the main battlefield of shale gas development in the“14th Five-Year Plan”in China.On the basis of introducing the operation status of traditional fracturing equipment,this paper analyzed its shortcomings in shale gas fracturing in Sichuan-Chongqing area,pointed out that fracturing equipment would develop in the direction of electric fracturing equipment and turbine fracturing equipment,conducted outlook on application of fault state monitoring and diagnosis system of fracturing set,fracturing energy storage(power transformation)system technology and low-voltage integrated Internet of Things(IOT)system technology in fracturing equipment,and further pointed out the development direction of fracturing technology and equipment in China,i.e.,development in the direction of environmental optimization,light weight and automation.The conclusions provide reference for the efficient development of shale gas and the field application and optimization of fracturing equipment in Sichuan-Chongqing area in China.
