对大港探区中区岩石粒间油气成因的显微迹象进行了荧光显微分析 ,对该区油气生成、运移、聚集及成藏规律进行了研究 ,并对油气资源进行了评价。结果表明 ,港古井区油气运聚具有上下小、中间井段相对大的规律 ,反映出本区生产的油气可能来自侧向运移 ,而具规模性的油气运聚主要发生于中间井段 ;而扣井区油气运聚则表现出明显不同成熟度的油气从下向上的纵向运移特征。表明岩石矿物粒间油气成因的显微迹象荧光特征研究是评价油气藏的一个重要补充 ,具有良好的应用前景
Fluorescence microscopic analysis of microscopic evidence of intergranular hydrocarbon generation in the mid-area of the Dagang exploration area was carried out. The laws of hydrocarbon generation, migration, accumulation and accumulation in this area were studied, and the hydrocarbon resources were evaluated. The results show that the hydrocarbon migration and accumulation in the Ganggujing area have the characteristics of small top and bottom and relatively large middle well sections, which indicate that the hydrocarbons produced in this area may come from the lateral migration, while the large-scale hydrocarbon migration and accumulation mainly occur in the middle well section. However, the hydrocarbon migration and accumulation in the well bore zone show the characteristics of vertical migration of oil and gas from bottom to top with obviously different maturity. The study of the microscopic fluorescence characteristics that indicate the genesis of oil and gas in the intergranular rocks is an important complement to the evaluation of oil and gas reservoirs and has a good prospect of application
