摘要(Abstract):
本文认为,丰富的油源和与之匹配的大面积发育的断续砂岩透镜体,是形成大面积岩性油藏的基本条件;凹陷中的大型鼻状构造和凹中脊具有控制沉积、诱导油气运移,并使之富集成带的作用。而起主导作用的砂岩透镜体和构造格局应是研究的主要对象。文中提到的一些具体作法,对隐蔽油气藏的勘探是有一定的参考价值的。
Abstract
It is considered in this paper that the rich oil source and its corresponding discontinuous sandstone lenticulars, which extensively developed, are the basic conditions for forming broad lithologic oil pools. The large nose-like structures and the ridge in the sag plaid the role of controlling deposition, inducing hydrocarbon to migrate and to concentrate in belt. The sandstone lens and structural framework, which play a quiding role in the formation of subtle oil pools, should be the principal objects of study. Some concret procedures described in the paper should be taken into consideration in the exploration for subtle oil pools.
