反转构造的识别及其地质意义

反转构造是构造地质学目前研究的热点之一,它是—种重要的叠加构造样式,与油气的生成、运移和聚集有着密切的关系,因而受到石油地质学家的高度重视。从几何学、运动学等角度对反转构造进行研究,认为不同性质和规模的构造反转,其发育规律、展布形式均不同,并对油气的运移和富集有重要作用。

Identification and its geological significance of inverted structure

Inverted structure is formed during the production,transition and alternating actions from compressive and extensional stress fields and is one of the popular investigations in tectonic geology especially petroleum structure study.As one of the important superimposed structural modes,inverted structure is closely related with formation,migration and congregation of hydrocarbon,so it can be considered as a very significant study object.The study of geometry and kinematics shows that the growing rules and distribution shape of the inverted structures with different characters and sizes is favorable for the migration and congregation of oil and gas.
