摘　　要：传统观点认为 :胡状集地区长垣断裂带油气不丰富 ,随着胡状集油田勘探开发的深入 ,越来越多的证据表明长垣断裂带的一些区块富含油气 ,因此有必要对长垣断裂的封闭性和断裂带油气聚集规律重新认识。长垣断裂带具备断层封闭性因素 ,并具有多种圈闭条件 ,而且是油气运移指向区域 ,在东濮凹陷的第二个生烃旋回 ,长垣断裂已基本停止活动 ,沙四 -沙三段生成的油气将沿断裂带的不封闭部分作横向及垂向运移 ,遇到圈闭时形成油气藏。对长垣断裂带油气聚集规律提出了看法 ,指出了下步有利勘探目标区。Traditional opinion is that there are no rich oil-gas reservoirs in Changyuan defaults belt in Huzhuangji area.With the development of exploration and exploitation in Huzhuangji oilfield,more and more evidence reveal there are rich oil-gas reservoirs in Changyuan defaults belt in Huzhuangji area. Therefore,Changyuan defaults sealing and the oil-gas assembling law in the belt must be researched further.Changyuan defaults own sealing factors.There are several types of traps in the belt.And the belt is the target of oil-gas produced from S 4～S 3 migrated by the way of unsealed parts in the vertical and transversal direction.When oil-gas arrived in traps,reservoirs had formed.The opinion on the law of oil-gas assembling in the belt is given.The oil-gas exploration targets of next stage are predicted.
