摘　　要：酸化对于碳酸盐储层改造是最有效的方法之一,在水力压裂技术广泛应用之前,致密砂岩油气藏也广泛应用,但效果不及碳酸盐储层改造。本文较为详细地介绍了酸化技术及其添加剂体系。应用该技术使川北阆中油气田开发取得了长足的发展,特别是酸压技术对大安寨储层改造必不可缺的技术措施。Acid stimulation is one of most effective methods to improve carbonate reservoirs. Before hydraulic fracture technique was applied extensively, it had been used in dense sandstone reservoirs, but the result is not so good as that of carbonate reservoir improvement. The paper introduces acid stimulation technique in detail as well as additive system. Great progress has been made in oil & gas exploration in Langzhong area in western Sichun province by using the technique, especially fracturing acidizing techniques have become necessary measures to improve Daanzhai reservoirs.
