摘要
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.
Petroleum system analysis is an important development in modem petroleum geology.It gives a comprehensive account to the formation,migration,accumulation,and dispersion of hydrocarbons in the light of geological evolution of sedimentary basins.It provides guidance for petroleum exploration by deeper understanding of the hydrocarbons distribution in petroliferous basins.Surface geochemical exploration has made certain successes in China but it is weak in anomaly interpretation.This paper tries to apply petroleum system analysis to the interpretation of the surface geochemical anomalies found in Sanggendalai sag.
