摘　　要：为了认识下寺湾油田延长组特低渗透储层开发过程中可能伤害储层的一些因素,在研究其岩石性质及矿物成分特征的基础上,通过敏感性流动试验对该区储层各种潜在敏感性进行了研究。结果表明,该区储层具有中等水敏性、较弱的盐敏性和碱敏性,没有酸敏性和速敏性,同时也分析了各种敏感性的成因机制,为油田开发提供可靠的研究及决策依据。In order to found out some potential factors that may hurt the reservoirs of the specially low permeability of Yanchang Formation in Xiasiwan oilfield during the development,the potential sentitivity of the reservoirs were evaluated based on the correct cognition of the reservoir's geology.The results showed that the water sensitivity obviously existed in these reservoir,salitiny and alkali sensitivity was feeble and there is no acid or velocity sensitivity.With the analysis of the reason that the sensitivity is come into being,the correct study was made for the development of the oilfield.
