在认真研究储层特征及伤害机理的基础上，根据室内试验结果，采用注有机溶剂前冲洗地层，然后进行土酸酸化解堵的工艺方法，成功地解决了冀东油田稠油井酸化的难题，现场应用58井次，有效42井次，有效率72．4％，截至1996年12月累计增产原油121532t，获得了好的经济效益。 Based on the study of reservoir characteristics and injury mechanism, based on the laboratory test results, using the process of flushing the formation before the injection of organic solvent and then acidizing and plugging the soil, the problem of acidizing thick oil wells in Jidong Oilfield has been successfully solved. In the field, 58 wells were used, 42 wells were effective, and the effective rate was 72.4%. As of December 1996, a total of 121,532t of crude oil was produced, with good economic benefits.
