Injecting green technology from the same well in North China to revitalize high-yield liquid gas wells

Sinopec News Network News As of June 2021, North China Oil & Gas Branch has applied 37 gas wells in the Dongsheng Gas Field with the same well injection technology, with a cumulative gas production of 3,839,900 cubic meters and a cumulative re-injection of 127,000 cubic meters of water.

Some gas wells in the Dongsheng Gas Field showed high liquid production and rapid gas production decline after being put into production.

Aiming at the problems of difficult to effectively release the productivity of high-yield liquid gas wells and environmental risks, through the integration of gas-liquid separation, bridge device flow passage conversion, and electric submersible pump drainage technology, the innovative integration of the same well production and injection technology has achieved high liquid production.

The same well injection technology has now become the "killer" technology of the North China branch, which has played an important role in expanding the scale of available reserves and maintaining SEC reserves
