| 摘 要： | 通过岩心分析化验资料(物性、薄片、铸体薄片、压汞等),详细分析了昆北断阶带切12号构造下干柴沟组下段储层的岩石学特征、物性特征和孔隙结构特征,并结合该区的构造与沉积等特征对储层物性的影响因素进行了分析.结果表明,研究区储集岩结构成熟度和成分成熟度较低、分选差,且泥质含量和黏土矿物含量高;储层物性差,且孔渗相关性较差;孔喉小且分选差,孔隙连通性差.研究认为,沉积环境、黏土矿物、泥质杂基和构造运动是影响储层物性的主要因素.

| Abstract: | Based on core analysis (including physical properties, cast thin section and mercury penetration), the charac-teristics of petrology, physical property and pore of Lower Ganchaigou Formation in Qie 12 structure of Kunbei fault zone are analyzed. Combined with the structure and sedimentary features, the influencing factors of reservoir properties are analyzed. The result shows that the reservoir rocks are of low textural maturity and compositional maturity, poor sorting, high content of shale and clay minera... |
