通过分析储层岩石性质、储层流体性质,然后再进行储层敏感性评价,为该区域后期开发提供依据。实验结果表明:储层岩石中黏土矿物含量降低,注入水矿化度在44 660~49 550 mg/L。该区域长2储层表现为弱速敏性、中等偏弱水敏性、无到中等偏弱酸敏和弱碱敏性。 By analyzing the rock properties of the reservoir, reservoir fluid properties, and then the reservoir sensitivity assessment, provide the basis for the late development of the region. The experimental results show that the content of clay minerals in reservoir rock decreases, and the salinity of injected water ranges from 44 660 to 49 550 mg / L. The Chang 2 reservoir in this area is characterized by weak fast sensitivity, moderately weak water sensitivity, moderate to weak acid sensitivity and weak base sensitivity.
