摘　　要：识别和预测渗流优势通道对提高砂岩油藏水驱波及体积具有重要意义。通过采用模糊综合评判法,开展江苏油田G6断块储层渗流优势通道的识别研究,预测出G6断块主力小层渗流优势通道的平面分布状况。将预测结果与动态分析、流管法、示踪法以及单井纵向剩余油饱和度测井等方法得出的结果对比验证,证实了运用模糊综合评判法开展针对江苏油田中低孔、中低渗砂岩油藏的渗流优势通道研究,具有较好的可行性与准确性。The identification and prediction of high permeability channel is significant for improving the waterflood swept volume of sandstone reservoir. Based on the fuzzy evaluation method, it was carried out study on identification of high permeability channels in reservoir of G6 fault block. And then the planar distribution pattern of high permeability channels was predicted in the major reservoir. The predicted result was verified by in the comparison of the results obtained by the methods including dynamic analysis, liquid - tube method, radiotracer method, logging of vertical remaining oil saturation of single well, and so on. The fuzzy evaluation method is reliable and accurate to study on the high permeability channels in mid - low porosity and mid - low permeability reservoir of Jiangsu Oilfield.
