| 摘 要： | 合川地区须家河组二段显示出较好的含油气性,通过对该地区岩心及铸体薄片观察分析,对该区须家河组二段的沉积相、岩石学特征、孔喉结构、成岩作用、物性特征及其主控因素进行了深入研究.认识到合川地区须二段岩性主要为岩屑长石砂岩和长石岩屑砂岩,属于三角洲前缘亚相沉积,水下分流河道和河口砂坝是主要储集砂体,储集空间类型主要为粒间孔和粒内溶孔,并搞清了合川地区须二段储层的成岩作用、物性特征及其控制因素,对加快合川地区须二段的勘探开发步伐具有重要的理论价值和现实意义. |

| Abstract: | This paper makes a thorough study of sedimentary facies,lithology,diagenesis,porosity,physical property and its control factors for the 2nd Member of the Upper Triassic Xujiahe Formation.The thin section study indicates that the 2nd member consists mainly of lithic arkose,feldspathic lithic sandstone of delta front deposit.The main reservoir sandy bodies were deposited in subaqueous distributary channel and distributary mouth bar with intergranular pore and intragranular pore as reservoir space. |
| Keywords: | the 2nd Member of the Upper Triassic Xujiahe Formation reservoir characteristic Hechuan region |
