摘　　要：针对江汉盆地古新世新沟嘴组砂岩储层具有中孔中渗—低孔低渗的特点,采用压汞、铸体薄片及物性分析等技术,以试油产量为依据,对孔隙结构类型进行了划分,揭示了砂岩储层各类孔隙结构与产油潜力的内在联系,指出喉道的大小是控制油层产量最重要的因素,为该区储层储集性能评价提供了重要依据。The pore have been classified structural types of the sandstone reservoir of the Paleogene Xinggouzui Formation in Jianghan Basin based on the analysis of mercury-injection, cast thin section, physical properties and oil testing production, in terms of the characteristics of mid-to-low porosity and permeability. The study has revealed the relationship between the pore structural types and oil production potential, and shown that the size of throat is the most important factor controlling the oil production potential of the sandstone reservoir. The study provides an important basis for reservoir evaluation.
