摘　　要：通过对东濮凹陷柳屯—海通集洼陷及周边油气藏特点及分布规律的研究,认为本区油气成藏条件良好,油气藏类型主要分为两大类八个亚类,不同类型油气富集程度不同,以反向、顺向断块、构造—岩性油气藏最富集,其次为断背斜、断鼻、墙角断块油气藏,而砂岩上倾尖灭、透镜状岩性及古潜山油气藏至今无大的突破。本文提出"洼陷的控边断层下降盘断层发育区或构造发育区,尤其是继承性构造发育区是下一步洼陷勘探最有利场所"的观点对本区及其他洼陷的油气勘探有重要指导意义。Based on the study of the hydrocarbon reservoir characters and distribution regularity of Liutun-Haitongji Sag in Dongpu Depression, the forming reservoir conditions are good and the types of hydrocarbon reservoir are divided into two types and eight minor types. The enrichments of oil and gas are different with different minor reservoir types. The best minor types are structure-lithology reservoirs, anti and consequent fault block reservoirs. The second minor types are fault-anticline reservoirs, fault nose reservoirs and fault block with corner formed two walls reservoirs. The third minor types are sandstone updip pinch reservoir, lensing-lihology reservoir and paleo-buried hill reservoirs without good discovery up to now. The beneficial exploration areas are fault or structure developing areas in downthrown block of the faults which are controlling the borders of the Sag, especially the inherited structure developing area. That point is significant to explore this area and the other sag.
