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

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.
