Sinopec News Network reported on August 23 that Southwest Oil & Gas Mapeng 1H well tapped the potential and achieved a daily gas production of over 60,000 cubic meters, which is the highest production well in the mid-shallow layer of the Western Sichuan gas field this year
.
The well is located in Sanjie Town, Pengzhou City, Sichuan Province.
The technicians of Southwest Oil and Gas Petroleum Engineering Technology Research Institute decided to reform the P21 layer of the well after thorough geological and engineering demonstrations
.
They adopted the pulsed plunger sand fracturing process, under the premise of ensuring the fracture length, appropriately increasing the sand ratio, reducing the amount of liquid entering the ground, and optimizing the fracturing fluid formula, reducing the water sensitivity of tight sandstones, and fully releasing the reservoir productivity
