摘　　要：用X衍射、全岩定量分析、薄片鉴定、扫描电镜、敏感性试验等数据,对鄂尔多斯盆地青阳岔油区长2储层敏感性进行研究。结果表明,研究区长2储层具有中-强碱敏、弱水敏、无速敏-弱速敏、无酸敏的储层敏感性特点。其中碱敏程度是控制研究区储层敏感性的最直接因素。The sensitivity of chang2 reservoir in qingyangcha oil area of ordos basin was studied by X-ray diffraction, whole rock quantitative analysis, thin section identification, scanning electron microscope and sensitivity test.The results show that chang2 reservoir in the study area has the characteristics of medium-strong alkali sensitivity, weak water sensitivity, no rate-weak rate-sensitivity and no acid sensitivity.Among them, alkali sensitivity is the most direct factor controlling reservoir sensitivity in the study area.
