| 摘 要： | 本文通过对威远、资阳地区上震旦统碳酸盐岩储集层中有机包裹体的研究，提出有机包裹体多分布于储层孔洞缝中所充填的三期矿物中，研究区油气运移的主要通道是溶蚀孔洞和裂缝。并根据不同期次充填矿物中有机包裹体特征、均一温度及单个有机包裹体成分，追索了研究区油气热演化程度、油气运移期次、油气运移的深度和温度。研究结果表明，研究区存在三次主要的油气运移和聚集，其各自演化的程度及油气运移的深度和温度皆不同。

| Abstract: | Based on the research of the organic inclusions in the Sinian Dengying carbonate reservoir of the Weiyuan gas field, it is sure that there are a great number of organic inclusions in filled minerals of three stages in pores, holes and fractures in the reservoir. It is thought that the pores, holes and fractures in the reservoir are chief channels of migration and accumulation of oil and gas. According to the characteristics and homogenization temperatures of the organic inclusions and gas composition of individual organic inclusions, the paper analyzes the oil-gas evolution history, stages, depth and temperature of oil-gas migration and accumulation. Result shows that there are three stages of oil-gas migration and accumulation in the Weiyuan gas field. They are different in evolution history, and depth and temperature of oil-gas migration and accumulation. |
