延长东区山西组山2段砂岩储层成岩作用及微观结构特征

Diagenesis and the microcosmic structure characteristics of sandstone reservoir of Shan-2 member of Shanxi formation in eastern Yanchang

本文通过铸体薄片、扫描电镜、阴极发光、X-衍射及压汞实验等进行样品实验鉴定,对山2段成岩作用对储层微观结构控制作用进行研究。为气田后续勘探开发提供指导。

The casting sections,scanning electron microscope（SEM）,cathode luminescence,X- ray and mercury penetrationare used in this paper for sample testing to study the diagenesis control on microcosmic structure of reservoir in Shan-2 block and provideguidance for further exploration and development of the gas field.
