Abstract: Based on the litholohy analysis,including the methods of thin section,scanning electronic microscope analysis,X-ray energy dispersive spectrum and electric probe analysis,X-ray diffraction analysis,cathodoluminescence analyis etc.The characteristic of sandstone reservoir in Bayanhua group in ErLian Basion has been studied,including the structure of rocks,and the type,amount and occurrence water-sensitive and acid-sensitive cement materials,some of the different measures to preventing the damage of oil-bearing formation have been proposed in this paper.

摘要： 本文使用岩类学分析方法(包括薄片鉴定、扫描电镜分析、能谱及电子探针分析、X衍射分析、阳极发光显微镜及荧光显微镜鉴定)对二连盆地阿尔善构造带、赛汉达拉凹陷、额尔淖尔凹陷下白垩系巴彦花群砂岩储层进行了研究,包括岩石的结构,油层中水敏性、酸敏性胶结物的类型、数量及产状并提出了不同的防止油层损害的措施。
