摘　　要：胡状集庆祖集断阶带构造位置位于东濮凹陷西部斜坡带中部 ,其主要生油、储油层系为下第三系 ,油气以生油洼陷向西部斜坡带运移为主 ,构造及砂体分布规律控制油气富集 ,二台阶是油气主要聚集区。该区主要发育构造油藏和岩性油藏 ,二台阶沙三下亚段沙四段是目前主要潜力区。The position of Huzhuangji-Qingzhuji fault step band is located in the middle of west slope of Dongpu Depression, where the principal oil generating and oil bearing reservoir is Eogene system ,the hydrocarbon migration is mainly from the oil generating sag to the west slope band . Oil and gas accumulation is controlled by the structure and sandbody distribution. The second step is the main abundance zone, where structural and lithologic reservoirs are principally developed . At present time the main potential zone is in the lower position of Es 3-Es 4 of the second step.
