| 摘 要： | 荷包场-界市场地区下三叠统嘉陵江组嘉二段气藏的主要储集岩为针孔白云岩,属海滩岩相。它处于低能环境海进序列的开始。储集空间为粒内、粒间溶孔及晶孔,是早期成岩过程中淡水淋滤和白云岩化作用的产物。储集岩的分布严格地受海进、海退和古高地控制。

| Abstract: | The major reservoir rock of the gas reservoirs in Member-2 of Jialingjiang Formation, Lower Triassic, at Hebaochang-Jieshichang region, is the dolomite with pinpoint pores, belonging to beach facies. It sat in the beginning of a transgressive sequence of low-energy enviroment. The reservoir spaces are composed of internal-and inter-granular solution pores and intercrystalline pores, being the products caused by the leach of fresh water and dolomitization in the process of early diagenesis. The distribution of the reservoir rock is seriously controlled by transgression, re-gression and ancient highland. |
