摘要：

该区有10套工业油气层。主要有滚动背斜、古潜山、浊积砂体、稠油封闭、地层起覆和断块油气藏。其主要的成油有利地质条件是:先凹后斜的斜坡油源丰富;多源多期的大砂体与隆起相结合有利于油气富集;两类平行斜坡的正断层控制了油气藏的形成;区域性大面积的盖层发育有利于油气保存。

Abstract:

The exploration practice of the west slope of the Liaohe Depression has veri-fied that a larg area of hydrocarbon enrichment can be formed on the slopebelt. There are several big oil and gas pools such as rolling anticline, buriedhill, turbidite sandbody, thickened oil zone, overlap belt and fault blocks overthere. There are four favourable conditions for hydrocarbon accumulation: a.The slope that depressed first and then declined is rich in oil source andfull filled. b.Multi-source and multi-stage huge sandbody associated with uplift isfavourable for hydrocarbon accumulation. c.The formation of oil and gas pools is contrlled by two kinds of normalfaults that are parallel to the slope. d.The extensively regional caprocks serve as a good preservation to oil andgas pools on the slope.
