For low-permeability oil reservoirs, ultra-high pressure rapid injection is used to increase formation energy, improve production pressure difference, and increase oil well productivity; Simultaneously improving the sweep coefficient and oil recovery efficiency, thereby enhancing the oil recovery rate.

486 well clusters have been implemented, with a water drive reserve of 170 million tons, cumulative water injection of 13.85 million cubic meters, daily oil production of 1001 tons, and cumulative oil production increase of 601300 tons.
