摘要
莺歌海盆地中中新统梅山组地层是盆地的主要烃源岩,它在盆地沉积中心的厚度达2000米。地质、地球物理和地球化学特征说明该地层有机质丰度高,且完全成熟;它处在深,热、封闭、含水和高压系统中。这种系统有利于烃类的生成、保存和运移,并且形成独特的模式——石油的深热成因和水相运移。
Meishan formation of middle Miocene is primary source rock in Yinggehai basin and 2000 m thick at the depocenter. According to geologic, geophysic and geochemic analyses it is sufficiently mature and rich in organics in a hot, deep, closed,water-wet and high-pressure system. The system is in a positive way for hydrocarbon generation, preservation and migration, and favors, of alll the currently available hypotheses, the model of a hot, deep origin and migration of petroleum by molecular solution.
