Abstract: Liuzhuang gas storage is reconstructed based on depleted oil and gas reservoirs. The formation pressure coefficient of injection and production gas Well X is only about 0.4 when drilling. Drilling fluid tends to permeate into the reservoir, leading to blocking of pore channels and reservoir pollution. Consequently, the daily gas injection capacity of the well was far lower than the designed daily gas injection capacity in the initial stage of production, so it is necessary to acidize and reform the well to remove pollution. This paper introduces in detail the acidizing liquid system and construction technology of Well X. The acidizing effect is comprehensively evaluated by analyzing the indexes such as construction curve, gas injection curve, indicator curve and reservoir parameters. The results show that the gas injection capacity of Well X is significantly improved after acidizing modification, which is basically consistent with the designed gas injection capacity and achieves the purpose of removing reservoir pollution. The acidizing construction technology and effect evaluation method for injection and production Well X in Liuzhuang gas storage can provide certain reference to similar injection and production wells in gas storages.
