摘　　要：储层损害机理研究是储层敏感性评价的最终目的,是储层保护可靠的理论依据。鄂尔多斯盆地新安边地区储层物性较差,属于中孔-低渗到低孔-特低渗储层,从敏感性实验分析入手,测量不同样品的敏感性指数,从而分析并确定了其各敏感性特征。The research of reservoir damage mechanism is used for reservoir sensitivity evaluation,which has been the reliable theoretical basis for reservoir protection. The reservoirs in Xinanbian Oilfield,Ordos Basin belong to middle porosity-low permeability to low porosity-extra low permeability reservoir in poor physical properties. This article demonstrates the sensitivity analysis experiments to detect the sensitivity index of different samples and determine the sensitivity characteristics of the samples.
