Successful completion of the first bow-shaped horizontal well in North China Oil & Gas

Recently, the first bow-shaped horizontal well J30-4-P11, designed by the North China Oil and Gas Exploration and Development Research Institute, was successfully completed
.

The well is located in the high-quality reservoir development area of ​​Jin 30 well area in Dongsheng Gas Field.
Due to the strong heterogeneity of the reservoir, the small scale and scattered distribution of the core beach, in order to achieve the maximum production of reserves and avoid interference from adjacent wells, Based on the idea of ​​"high yield in wells", the horizontal section is optimally designed into a bow shape
.

The horizontal section of the well is 800 meters long, with a sandstone encounter rate of 95.
9%, and the horizontal section was drilled in only 7 days
.
The successful implementation of this well provides a new model for effective production of strong heterogeneous reservoirs and thin, small, and scattered central banks
