目的:分析断裂的几何学、运动学特征及断裂构造特征与油气聚集关系。方法:结合构造的圈闭条件进行综合评价,寻找有利油气聚集区。结果:大洼断裂控制着清水洼陷及东侧中央凸起的发育,是油气运移的主要通道;二界沟断裂在本区是一条油源断层;新开断裂对新开鼻状断裂构造带的形成及油气的分布起着重要的控制作用。结论:大洼小洼以及新开地区为主要的有利勘探区。
Objective: To analyze the fracture geometry, kinematic characteristics and fault structure characteristics and hydrocarbon accumulation. Methods: Combining with the trapping conditions of the structure, a comprehensive evaluation was carried out to find a favorable hydrocarbon accumulation area. Results: The Dawa fault controls the development of the Qingshui sag and the central bulge on the east side, which is the main channel for oil and gas migration. The Erjiegou fault is an oil source fault in this area. The newly opened fault has the effect on the newly opened nose-like fault structure The formation of belts and the distribution of hydrocarbons play an important role in controlling. Conclusion: Dawa depression and Xinkai area are the major favorable exploration areas.
