詳細說明

The well was shut in in July 2021 due to no liquid production. Analysis suggests that the formation blockage caused a decrease in liquid supply, and manual inspection showed no sand production. In November 2021, acoustic cavitation was implemented to remove blockages in the well. After the measures were taken, the liquid production index of the well increased to 353m 3/d.MPa, with a daily liquid production of 4500-5000 barrels and a water content of 95.8%. The production capacity increased by more than twice compared to before sand production, while the water content decreased by 1%. The average daily oil production was over 188 barrels, and it remained effective for more than 10 months.
