摘要
汉留断裂带是高邮凹陷重要的油气富集带,在对汉留断裂带构造几何学及运动学特征分析的基础上,明确了汉留断裂带发育6种构造样式,其断层平面组合和剖面形态自西向东具有三段式分布特征:西段拱张式、中段扭张式和东段拉张式。主干断层演化具有西早东晚、中段强两端弱的特征。汉留断裂带构造展布及演化的差异性主要受控于深部岩浆上拱及不同时期应力场方向的转变。
Hanliu fault zone is an important prolific zone for oil and gas accumulation. Based on the structural geometry and kinematic characteristics of Hanliu fault zone,there are 6 types of structures in the fault zone. The fault plane combination and the profile shape have three-segment features from west to east： arched-extension type in western section,transtension type in middle section and tension type in eastern section. The evolution of main faults has characteristics of the earlier in the western than the eastern and the stronger in the middle than that at both ends. The difference of structural distribution and evolution is mainly controlled by the upper arching of deep magma and the change of stress field in different periods.
