Recently, the horizontal well J66-5-3 in the production capacity construction of the Jin 66 well area of North China Petroleum and Chemical Corporation has obtained a daily gas production of 39,000 cubic meters
.
This well is the first short-radius horizontal well deployed for small-scale lithology-structural gas reservoirs this year, with a horizontal section of 500 meters long
The Jin 66 well area has complex structure, narrow channel, rapid reservoir change, and complicated gas-water relationship
.
In this regard, the technical staff of the North China Oil and Gas Exploration and Development Research Institute finely described the gas reservoirs and carried out integrated geological-seismic research.
