| 中文摘要: |
| 根据埕北断坡区三维地震资料,探讨了主要断层的构造特征;依据石油运移地球化学资料和油气分布特征,研究了主要断层对油气运移的控制作用。结果表明,研究区油气以沿断层垂向运移方式为主,以侧向运移为辅,该区油气藏类型多与断层有关,主要圈闭类型为断块和断鼻型。据此建立了油气沿断裂运移的模式,并预测了有利的油气聚集区域。认为歧东断层和张东断层之间、张北断层和张东断层之间、海4井断层和羊二庄断层之间等区域以及关家堡—埕海地区为有利勘探区。 |
| 英文摘要: |
| 3-D seismic data of Chengbei fault-ramp reveals that oil and gas mainly migrated along the vertical direction of the faults,and less in the lateral direction and oil-gas migration model along faults is set up.Fault block and nose are the main traps.Then the favorable prospecting targets were predicted,such as the areas between Qidong fault and Zhangdong fault,Zhangbei fault and Zhangdong fault,Hai 4 well fault and Yangerzhuang fault as well as the Guanjiabao-Chenghai area. |
