华庆地区是长庆油田2009年投入开发的一个新区块,为使区块合理高效的投入开发,就必须掌握储层敏感性特征。利用岩心薄片及X衍射分析了长6储层潜在伤害的矿物成分,使用流动实验评价了储层的敏感性特征。研究结果表明,长6储层敏感性特征表现为弱水敏、弱～中等酸敏、弱盐敏、弱速敏、弱碱敏。 Huaqing area is a new block put into development of Changqing Oilfield in 2009. In order to make the block reasonable and efficient into development, it is necessary to grasp the characteristics of reservoir sensitivity. The core components and X-ray diffraction were used to analyze the mineral composition of potential damage in Chang 6 reservoir. The flow characteristics were used to evaluate the sensitivity of reservoir. The results show that the sensitivity characteristics of Chang 6 reservoir are weak water sensitivity, weak to moderate acid sensitivity, weak salt sensitivity, weak fast sensitivity and weak alkali sensitivity.
