胜坨油田坨28断块沙二段上亚段油层组水淹层测井评价模型

应用岩心刻度测井和动、静态相结合的方法，建立了坨28断块沙二段上亚段油层组地质条件约束下的水淹层测井精细解释模型，并对381口水淹层常规测井资料进行了处理和综合评价，评价解释结果与生产测试结果吻合较好。应用研究成果有效指导了坨28断块沙二段上亚段油层组综合调整方案，对该区15口新井的单采层进行了水淹层评价效果的现场检验，按水淹级别统计，符合率达到80％，表明该方法具有很好的实用性和推广价值。

Logging evaluation model of water flooded zone in oil formation in upper Es2 of Tuo 28 fault block

By using the core calibration logging and the method of combination of dynamics and statics, the fine log interpretation model for water flooded zone under the restriction of geologic condition of oil formation in upper Es2 of Tuo 28 fault block is established. The procession and comprehensive evaluation are made for the conventional logging data from 381 water flooded wells by this model. Its results tally well with production testing results. The results give effective guiding on comprehensive adjustment project of oil formation in upper Es2 of Tuo 28 fault block. Evaluation effect of water flooded zones among the single production zones of 15 new wells in researched area is tested. According to the criterion of water flooded zone, the coincidence rate reached 80 percent, which proved that this method has good practicability and spreading value.
