通过对威远气田灯影组碳酸盐岩储层中有机包裹体的研究，确定了该储层孔隙、孔洞和裂缝中3个阶段的充填矿物中存在大量的有机包裹体。认为储层中的孔、洞、缝是油气运聚的主要通道。根据有机包裹体的特征、均一温度和单个有机包裹体的气体成分，分析了油气演化历史、期次、油气运移聚集的深度和温度。结果表明，威远气田油气运移聚集经历了三个阶段。它们的演化历史不同，油气运聚的深度和温度也不同。
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.
