Sinopec News Network reported on September 22 that the He 4 section of Well Bin 3 in the Binchang Exploration Area of North China Oil and Gas Branch was fractured with mixed water volume and obtained a high-yield industrial gas flow of 27,000 cubic meters per day.
After the first stage test with a daily output of 15,000 cubic meters, the Upper Paleozoic tight gas exploration in the Binchang exploration area has made another breakthrough, setting a new high in the production capacity of the He 4 section of the area
.
Well Bin 3 is a pre-exploration well deployed in the southern part of the Yishan slope in the Ordos Basin.
The purpose is to verify the gas-bearing properties of the Lower Paleozoic and Upper Paleozoic reservoirs in the Binchang exploration area and prepare for reserves upgrade
.
In view of the development characteristics of natural fractures in the 4th member of this well, in order to expand the reservoir reconstruction volume, the design adopts the mixed water volume fracturing concept
.
The production breakthrough in the He 4 section of Well Bin 3 further confirms that the mixed-water volume fracturing technology has good adaptability in natural fractured reservoirs, demonstrating the good gas-bearing and gas-bearing properties of the Upper Paleozoic tight sandstone gas reservoirs in the Binchang exploration area.
