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。 According to the geological characteristics of reservoir in Xifeng Oilfield, the indoor evaluation results of reservoir acid sensitivity were analyzed. Based on the existing acid system evaluation of Xifeng Oilfield, the dissolution test of acid solution and reservoir rocks was conducted. According to the results of erosion test and Different acid system reactivity and reaction mechanism, and with reference to the acidification research results and practical experience of Xifeng Oilfield in the past, the acid formula system suitable for Xifeng Chang 8 reservoir was screened out. Finally, according to the past acidification experience in the area, the acid formulating system is improved and improved.
