摘要
油气的生成、运移、聚集和散失,是在盆地形成、发展直至萎缩的石油地质演化过程中,各种沉积物经历了一系列物理、化学变化共同作用后的产物。烃源岩的初次运移过程,应当是在卸载减压物理场条件的诱发作用下,先产生烃源岩“破裂排烃”,然后是“排烃压实”,最终才导致“压实排烃”。区域概念上就可以把石油聚集量理解为石油排出量。盆地全面萎缩发展阶段是盆地油气藏的最终完善定型期。
Hydrocarbon generation, migration, accumulation and diffusion loss are the products of sediments after a series of physical and chemical changes during basin formation, development and withering. The first migration of oil and gas is caused by physical field of unloading and decompression. Source rock experiences cracking and hydrocarbon expulsion at first, and then hydrocarbon expulsion and compaction, and finally compaction and hydrocarbon expulsion. Oil accumulation quantity can be comprehended as oil expulsion quantity territorially. Basin withering stage is the period of reservoir consummating and definitizing.
