摘要
通过对沉积埋藏史、生烃史及油气运聚史的研究 ,确定烃源岩生、排烃及油气运聚期次 ;结合稠油物理、地球化学性质复杂变化的特点 ,以阶段性成藏各过程为线索 ,分析各阶段稠油形成的主要控制因素 ,理清了稠油的形成机制 ,建立了石油稠化模式 ,总结了石油的分布规律 ;提出了“多种烃源岩、多个成藏期及多种石油稠化作用控制重油成因与分布”的新观点 。
The stages of oil generation, expulsion, migration and accumulation are determined through study of depositional history, oil generation and migration and accumulation history. Main controlling factors of heavy oil generation in each stage are analyzed as per the complicated physical and geochemical properties of heavy oil. This paper introduces heavy oil generation mechanism, sets up oil densification mode, summarizes oil distribution law, puts forward a new viewpoint that 'heavy oil genesis and distribution were controlled by multi source rock, multi reservoir forming period and multi oil densification effect', and broadens the thought for the study of heavy oil genesis and distribution.
