摘要
根据乌南地区压汞样品149余块，铸体薄片100余块以及60余块图像孔隙分析结果，参考前人储层分类研究结果，采用流动单元分类方法，对可提取的储层特征参数，根据其对储层的敏感性分析和大量的实际井处理资料，将该地区储层分为四类：低渗透层（Ⅰ类）、特低渗透层（Ⅱ类）、超低渗透层（Ⅲ类）、致密层（Ⅳ类）。为提高流动单元的识别精度，对常规的流动层带指数法进行了改进，然后以改进的流动层带指数法为主，根据K／Ф对储层进行了划分，最后用流动单元划分法验证所做分类，取得了较好的效果。
According to more than 149 mercury penetration samples,100 casting sheet images and 60 porosity analysis results,the paper makes a reference to previous reservoir classification results,and then adopts to flow unit classification method for some selection reservoir characteristic parameters to divide the reservoir into four types,namely,low permeability layer(Ⅰtype),lower permeability layer(Ⅱtype),lowest permeability layer(Ⅲtype) and tight layer(Ⅳtype) on the basis of the sensitiveness of the reservoir analysis and a lot of filed processing data. In order to improve identification precision of the flow unit,we modify the conventional flow belt index number,and then use the modified flow belt index number to divide the reservoir in with the light of K/Φ.Finally,we verify the classification results by the method,and the result shows that the classification is good.
