摘　　要：油气井在开采过程受地层岩敏感性等因素影响,造成地层孔隙吼道堵塞、储层渗流能力下降。特别是注水井由于储层堵塞,使得注水压力较高,注水指标难以完成。分析了酸化解堵工艺要点,配制了酸液、解堵液配方,制定了施工工艺参数,为储层酸化解堵提供经验借鉴。In the process of oil and gas well exploitation,the formation pore roar channel is blocked and the reservoir seepage ability is decreased because of the formation rock sensitivity and other factors.In particular,due to the blockage of the injection wells,the injection pressure is high and the water injection index is difficult to complete.The key points of acidizing plug removal technology are analyzed,the formula of acidizing fluid and plug removal fluid is prepared,and the operation parameters are formulated,which can provide experience for reservoir acidizing plug removal.
