摘要: 在含油气盆地中 ,断裂构造是决定油气分布的重要因素。在详细研究垦利断裂带构造演化及断裂构造特征的基础上 ,探讨了该地区断裂构造对油气运聚的控制作用 ,并根据在垦利断裂带已发现的油田 (藏 )总结出了同层成藏、潜山成藏、跨断层成藏和沿断层成藏 4种成藏模式 ,认为该地区的油气分布受构造因素控制Abstract: Faulted structures are the key factors defining hydrocarbon distribution in a basin. The control of faulted structures on hydrocarbon migration in this area is discussed on the basis of detail study on structural evolution and features of the faulted structures in the Kenli fault zone. Four reservoir-forming patterns are summarized on the basis of the reservoirs discovered in this zone. It is concluded that hydrocarbon distribution is under control of structural elements in this area.
