摘　　要：在分析凤冈区域地质构造演化的基础上,对下寒武统牛蹄塘组的页岩层裂缝特征进行了研究。研究表明:多期次强烈的构造运动使该区域断裂发育复杂,造成多个断裂体系相互交错、切割,从而形成以隔槽式为主的褶皱形体;从储层裂缝特征来看,主要以构造裂缝为主,横裂缝、垂直裂缝占主体,部分岩心破碎严重,并且裂缝大部分被其他矿物成分充填,以石英、方解石充填所占比例高。On the basis of analysis of the regional geological tectonic evolution in fenggang area, Cambrian Niutitang formation shale fracture characteristics was studied. Research shows that：a period of time more intense tectonic movement made the fracture development in the area complex, and caused multiple fracture system mutual crisscross, cutting, resuhing in the folding form which is given priority to with wide spaced syncline bodies;Standing in fracture characteristics,tectonic fracture is the mai. the core broken seriously ,and cracks in most other calcite filling. the perspective of Niutitang formation shale core horizoutal.vertical cracks of the main body,part of mineral composition,filling with high proportion of
