摘　　要：结合西峰油田储集层地质特征,对储层酸敏性室内评价结果进行分析,结合西峰油田现有酸液体系评价,进行酸液与储层岩石的溶蚀性试验研究,根据我们溶蚀试验结果和不同酸液体系的反应性和反应机理,并参考以往西峰油田酸化研究成果和实践经验,筛选出适合西峰长8储层的酸液配方体系。最后又根据该区以往酸化实践经验,对该酸液配方体系进行完善和改进。Combined with geological characteristics of Xifeng oilfield reservoir,reservoir acid sensitive laboratory evaluation results were analyzed.Based on Xifeng oilfield existing acid system evaluation,the erosion test of reservoir rock in acid was carried out.According to the test results and reactivity and reaction mechanism of the different acid systems,referred to Xifeng oilfield acidification research results and previous practical experience,the suitable acid formula system for Xifeng Chang 8 reservoir was screened.Finally,the acid formula system was improved based on the practical acidifying experience in the area.
