摘　　要：东濮凹陷西部斜坡带胡庆地区为东倾断阶构造,已发现油气主要集中在二台阶的构造圈闭之中,勘探程度高,靠近洼陷带的一台阶发现较少,勘探程度低。随着勘探工作的不断深入,一台阶的勘探潜力成为中原油田近些年来重点关注的问题。综合分析认为:一台阶靠近生烃中心、具有优越的油源条件;受华北运动Ⅱ幕构造运动影响,西部斜坡带表现出两次生烃、两期成藏的特点,东营组时期长垣断层作为运移通道将洼陷带油气运移至二台阶成藏,东营期之后长垣断层停止活动,具有封闭油气的能力,晚期生成的油气主要聚集在一台阶。Huqing area is a east dipping fault terrace in western slope zone of Dongpu Depression,The discovered oil and gas are mainly enriched in the structure trap of the second terrace with high degree of exploration,however,the discovered accumulations are less in the immature first terrace of approching depression.With the increase of exploration,the exploration potential of first terrace has become an important focus of Zhongyuan oilfield in the past few years.According to the comprehensive analyses,the first terrace is close to the center of hydrocarbon genneration and has the superior oil source condition.With influenced of the second episode tectonic movement of the North China movement,the western slope displays the characteristic of two times hydrocarbon generation and accumulation.In Dongying stage,the Changyuan fault was the migration fairway between depression and the second terrace.After Dongying stage,the Changyuan fault is inactive and has the sealing capacity.So petroleum are mainly accumulated in the first terrace.
