Shichao completes 3-3HF large sand fracturing

On September 14, the Southwest Acid Field Fracturing Brigade of the Southwest Oil & Gas Field successfully implemented 8 large-scale sand fracturing operations in the Shijiazhuang 3-3HF horizontal well, adding 361 cubic meters of sand.

The Shifang 3-3HF well is a horizontal development well deployed by the Southwest Oil and Gas Branch in the north slope of the Deyang syncline in the Sichuan-Western depression of the Sichuan Basin. The horizon belongs to the Penglaizhen Formation with a horizontal section of 1,297 meters. It was drilled on May 7, 2012. According to drilling, well logging, and logging data, the well can be reformed by the horizontal sand fracturing method to form a suitable artificial fracture in the sand body, increasing the effective seepage radius and control of the well. Gas area, in order to achieve the purpose of increasing production capacity and improving recovery factor.

It is reported that since entering the western Sichuan Basin to increase storage and production competition, the Southwest Oil and Gas Field has successfully implemented a large number of large-scale sand construction, and achieved good results, and the construction of the 3-3HF is the sixth port of more than 300 cubic meters of sand Large fracturing.
