摘　　要：基于对准噶尔盆地某砾岩油藏的淡水水淹机理的实验认识,考察了砾岩油藏水淹层的测井响应特征,形成了一套定性识别水淹层和划分水淹级别的方法.在该基础上,按照"岩心刻度测井"的原则,统计建立了一套适用于该砾岩油藏淡水水淹层的测井评价方法.该方法在7个区块17口井的测井解释结果表明,水淹级别按6级划分的解释符合率达85%左右.Based on the knowledge of freshwater flooding mechanism of the conglomerate reservoir in the X Oil Field of Junggar Basin, the characteristics of well logging information are examined. A qualitative method is set up to identify the watered-out zone and evaluate the flooding level. Further, in accordance with the principle of ＂core analysis scale well logging ＂, a set of statistical models are set up for the quantitative evaluation of freshwater watered-out zones in the conglomerate reservoir in the X Oil Field of the Junggar Basin. The method is applied to interpret the well logging data of the 20 wells in 7 areas. The result shows that six flooding levels are made off and the accuracy is about 85%.
