摘要
汉留断裂带是高邮凹陷重要的油气富集带,本文在对汉留断裂带构造平面及剖面特征分析的基础上,明确了汉留断裂带发育6种构造样式,其断裂平面组合和剖面形态自西向东具有三段式特征:西段拱张式、中段扭张式和东段拉张式。结合主干断裂活动性分析认为汉留断裂带构造样式的形成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 study of the plane and vertical structural geometry character of Hanliu fault zone,it is addressed that there are 6 types of structural styles in the fault zone.The combination of fault plane and the profile shape have three segment features from west to east,which are arched-extension style in west,transtension style in the middle and tension style in the east.Combined with evolution of the main faults,the difference of structural style of faults is mainly controlled by the upper arching of deep magma and the change of stress field in different periods.
