摘　　要：应用毛细管压力曲线可定性研究储层孔隙结构特征,根据储层物性和孔隙结构特征资料对储层进行分类。以上三叠统延长组长6段储层为例进行分类研究,结果表明:该储层为低孔、低渗、特低渗储层。根据储层物性和结构特征,将本层段分为3类储层。从而为该层的进一步合理开发提供了可靠的地质依据。Capillary pressure curve can be applied to study the characteristics of reservoir pore structure. Reservoir can be divided by using reservoir properties and pore structure characteristics. Chang 6 reservoir of Upper Triassic Yanchang Formation is studied. The result shows that the reservoir is of low porosity and low permeability. According to the reservoir properties and structure characteristics, Chang 6 is divided into three types of reservoir, which provides reliable geological basis for further development.
