摘要
油气藏的封盖机制是油气藏形成机制的重要内容.对上倾方向上有封盖层的油气藏(即常规油气藏,包括背斜圈闭、上倾型构造及地层圈闭)的封盖机制和上倾方向上没有封盖层的油气藏(深盆气藏)的封盖机制进行了综合分析,并指出其存在的问题,认为应加强油气封盖与油气运移和聚集相关性的研究.
Seal mechanism is an important content of oil and gas accumulation mechanism.This paper studies the seal mechanism of the trap which updip direction has the cap-rock (including anticlinal trap, updip structure and stratigraphic trap) and the trap which updip direction did not has the cap-rock (deep basin gas trap).It s suggested to strengthen the research of the correlation among the seal,migration and accumulation.
