摘要: 从辽河坳陷西部凹陷油气藏勘探现状分析入手,通过对西部凹陷各种类型岩性油气藏的成因研究,认为西部凹陷虽已进入高成熟勘探阶段,但岩性油藏的勘探仍具有相当的潜力。在总结各种类型岩性油藏展布特征的基础上,指出下步勘探主攻方向应由寻找构造油气藏为主向以寻找岩性油气藏为主的方向转化。根据岩性油气藏的展布特征确定了下步勘探的主攻方向:即鸳鸯沟—齐家地区、台庄—大洼断层下降盘、清水洼陷东营组、兴隆台—马圈子潜山带、西斜坡潜山带。

关键词: 辽河坳陷, 西部凹陷, 坡洼过渡带, 岩性油气藏

Abstract: Starting with analyzing the exploration status of oil-gas reservoirs in western sags of Liaohe Depression, it is thought that the western sags have entered into high mature stage of exploration,after the origins ofvarious-type lithologic reservoirs in western sags were studied, but there is still a considerable potentialfor lithologic oil reservoirs to explore.On the basis of summarizing on distributioncharacteristics of variouslithologic reservoirs, it is pointedout that, the majorfuture exploration fields should be turned to lithologic reservoirexploration fromstructural reservoir exploration,and the next exploration targets will focus on the following areas, i.e.Yuanyanggou-Qijia area, the downthrough side of Taizhuang-Dawa fault, Dongying Formation in Qingshui sag,Xinglongtai-Maquanzi burial hills belt and burial hills belt in western slope

Key words: Liaohe Depression;western sag;transitional zonebetween sag and slope, lithologic oil-gas reservoir
