On March 26, 2023, 6 wells of the SWOG Yang 101H53 platform successfully completed the 140-stage fracturing construction. The platform adopted an all-electric drive fracturing construction operation mode, accumulatively using 6.26 million kilowatt-hours of grid power, reducing more than 2,400 tons of diesel oil, and reducing carbon emissions More than 7,400 tons have provided valuable experience for the large-scale application of all-electric fracturing construction in grid power operation, construction organization, fracturing technology, and investment control.

The Yang 101H53 platform is a shale gas development platform deployed by SWOG in the Baozang syncline of the Yanggaosi Structural Group in the southern Sichuan low-fold belt of the Sichuan Basin. platform, the fracturing time of the platform is 1.91 sections/day, 19 days ahead of schedule.

During the implementation process, SWOG aimed at the effective transformation of the reservoir and rapid production, and adopted the integration of geology and engineering and the multi-cluster + high-strength sand addition + large-displacement pump injection + temporary plugging and diversion to the main process. Optimize and adjust the implementation plan, reduce the risk of casing change, improve the effect of transformation, ensure the smooth operation of fracturing construction, and achieve the goals of zero accidents, zero casing change, and zero lost sections. The intensity of sand addition and liquid use meet the design requirements; The platform carried out field tests of new temporary plugging techniques such as temporary plugging knots, temporary plugging cones, etc., to further improve the technical level of Luzhou deep shale gas temporary plugging technology.Editor / He Yurong
