摘　　要：在对鄂尔多斯盆地某地区长8段储层绿泥石衬边成岩相中绿泥石类型、绿泥石衬边成岩相抑制石英次生加大的机理进行分析基础上,提出了利用常规测井资料连续定量计算储层的绿泥石含量、主要粒度平均值,建立视覆盖率的计算模型、方法和以视覆盖率为标准的绿泥石衬边成岩相有效性识别图版。利用该图板对研究区常规测井资料进行处理,通过与扫描电镜鉴定结果对比,验证了图版的准确性。Based on the research of chlorite types and the mechanism of chlorite coats diagenetic facies inhibiting quartz increase in the reservoirs of Chang 8Formation in Xarea,Ordos Basin.This paper present that the conventional logging data can be used to continuously and quantitatively calculate the reservoir＇s chlorite content,average size of main particle,build up the computation model and method of apparent-coverage rate,and the chlorite diagenetic facies based on apparent-coverage rate can effectively recognize the chart,which can be used to process the conventional logging data and verify the accuracy of the chart by comparing with the scanning electron microscopy identification results.
