摘　　要：为了南泥湾油田持续稳定生产,对X区储层敏感性特征进行了细致深入的研究。利用岩心流动试验,对X区长4+5储层进行了水敏感性、速度敏感性、盐敏感性、酸敏感性及压力敏感性实施定量标准化评价。结果显示,X区长4+5储层为中等-强酸敏,后期开发时应尽量避免酸化。简要分析了储层的敏感性机理,为油田后期开发提供有力支撑。In order to maintain and stabilize the production of Nanniwan Oilfield,the reservoir sensitivity characteristics of Zone X have been carefully and deeply studied.The test is used to carry out quantitative standardized evaluation on the velocity sensitivity,water sensitivity,salt sensitivity,acid sensitivity and pressure sensitivity of the Chang 4+5 reservoir in this area.The research results show that the Chang 4+5 res-ervoir in this area is moderately to strongly acid-sensitive,and acidification should be avoided as much as possible during later development.At the same time,the sensitivity mechanism of the reservoir is briefly analyzed to provide strong support for the later development of the oilfield.
