我国多为陆相叠合盆地,具有多期生排烃、运移、成藏、调整和破坏的特点。归纳有关油气运移方面的文献,将油气运聚期次的研究方法归纳为4种:即以分析构造运动后地层表现形式的构造分析法、以研究流体包裹体为主要内容的储集层有机岩石学分析法、储集层成岩矿物(主要是伊利石)同位素地质年代法和用于推断储集层中烃类流体充注史、烃类注入方向和时间的油藏地球化学-油藏非均质性研究法。4种方法分别具不同的分析原理和应用效果,并在吐哈盆地分别进行了应用。构造分析法和储集层有机岩石学分析法得出葡北油田主要经历了侏罗纪末─早白垩世和晚第三纪两期油气大规模运移;葡北油田同位素地质定年分析只反映出油气第二期运移成藏时期,其原因是第一期油气没有充满取样层位所造成;油藏地球化学-油藏非均质性分析得出鲁克沁构造油藏是油气先稠化后成藏的结论。
Most of our continental superimposed basin, with multiple stages of hydrocarbon generation, migration, accumulation, adjustment and destruction characteristics. The literature on oil and gas migration is summed up and the research methods of hydrocarbon migration and accumulation are summarized into four types: structural analysis method for analyzing formation behavior after tectonic movement, reservoir organic matter with fluid inclusion as the main content Petrology, reservoir isotope geochronology of diagenetic (mainly illite) and reservoir geochemical-reservoir non-reservoir predictions of hydrocarbon fluid charge history, hydrocarbon injection direction and time in reservoirs Homogenization research method. The four methods have different analytical principles and application effects, respectively, and were applied in Turpan-Hami basin. Tectonic analysis and reservoir organic petrology analysis show that the Pubei oil field mainly experienced the large-scale oil and gas migration from the end of Jurassic to the Early Cretaceous and the Late Tertiary. The isotopic geo-dating analysis of the Pubei field only reflects The second stage of hydrocarbon migration and accumulation was due to the fact that the first phase of oil and gas was not filled by the sampling beds. The analysis of reservoir geochemistry and reservoir heterogeneity showed that the reservoir of Luqinqin structure is mainly composed of oil and gas After the formation of the conclusion.
