摘　　要：本文分析了辽河曙一区大民屯油田储层用盐酸和土酸酸化效果不佳的原因，研制成功了脂肪族混合低碳羧酸酸化液，在数口井的现场试验中获得了初步成功。介绍了该酸化液的组成和特性：作用持续时间长，不产生二次沉淀，可分散、溶解沥青胶质等有机质，有润湿反转作用。The results of acidizing sandstone reservoirs in Damintum Qil Field at region Shuguang 1, Liaohe. by inorganic acids were unsatisfactory. Instead of these acids an acidizing fluid based on unpurified mixed aliphatic carboxylic C1-C3 acids containing various organic substances is developed and tested in several oil wells with definit success acidizing fluid(of C1-C3 acids ～90% totally) reacts with reservoir rock in a prolonged time without calcious. ferreous and siliceous precipitations formed and can disperse and dissolve asphatlic-resineous and other organic substances. The mixed acids are prepared from by-product of soap-detergent manifacturing.
