孤岛油田中一区测井资料精细解释

Fine Interpretation of Well Logging Data from Zhongyi Area in Gudao Oil Field.

申辉林，李厚裕，谢毫元．孤岛油田中一区测井资料精细解释．测井技术，１９９７，２１（３）：２２７～２３２我国东部大部分油田已进入中、高水淹期。油层水淹后，测井机理发生了很大的变化，原来的解释模型已不能满足生产要求。本文采用关键井分析技术，建立适应于研究区域不同水淹级别地层的测井解释模型，用校正后的自然电位曲线求准地层混合液电阻率的方法，定量评价孤岛油田中一区中、高水淹层的测井资料，其解释结论与试油结果相比较，水淹层分级定量解释符合率高达８０％，取得了良好的效果。

Most of the oilfields in eastern China have entered into middle or high watered out stage. Conventional log interpretation model can ′t meet the demands of production because log mechanism has changed noticeably after watered out. Based on key well analytical technique, log interpretation models adapted to different watered out levels and different areas are set up. And a method for calculating mixed formation water resistivity with the corrected SP data is used to quantitatively evaluate middle or high watered out zones in Zhongyi area, Gudao oilfield. Compared with the well test results, the coincidence rate of log quantitative interpretation for various watered out levels is above 80%.
