摘要(Abstract)：

根据铸体薄片、扫描电镜、压汞实验等数据,采用微米CT高分辨率成像技术和微米CT充注驱替实验,定量识别储集空间类型,表征储集空间微观结构特征,研究库车坳陷克深井区白垩系巴什基奇克组致密砂岩储集空间对含气性的影响。结果表明:研究区目的层致密砂岩储层储集空间的类型为孔隙和微裂缝,孔隙提供主要的储集空间,是气体主要的赋存场所,微裂缝储集气体的作用是次要的;给定压力条件下,致密砂岩储层含气性受控于气体可进入的连通储集空间(体积大于104μm3)的体积;微裂缝的发育沟通不连通的孔隙,对改善致密砂岩储层的含气性更重要。该结果为克深井区巴什基奇克组致密砂岩储层进一步勘探和开发提供指导。
