成油体系分析是近年来石油地质学上的一项重要进展,它将石油的生成、运移、聚集、分散的全过程与盆地演化的地质历史有机地结合起来,通过更深刻地揭示任一特定盆地中油气资源的形成与分布规律来指导油气勘探工作.地表油气化探在我国虽然已取得一定的成果,但在异常解释方面依然十分薄弱.应用成油体系分析的方法对桑根达来凹陷的地表化探异常进行了综合解释,即把地表化探异常当作该盆地中成油体系的一个组成部分来研究,从而对异常有了更深入的认识.
Oil system analysis is an important advance in petroleum geology in recent years. It organically combines the whole process of oil formation, migration, aggregation and dispersion with the geologic history of basin evolution. By further revealing either The specific formation and distribution of oil and gas resources in specific basins to guide oil and gas exploration.Although some achievements have been made in the exploration of surface oil and gas in China, it is still very weak in the anomalous interpretation.Using the method of oil system analysis, A comprehensive interpretation of the anomalous surface geochemical anomalies in the sag has been carried out, that is, studying the anomaly of the surface geochemical anomalies as an integral part of the medium oil system in the basin, and thus getting a deeper understanding of the anomaly.
