聚合物驱后水淹层测井解释模式

针对老区聚合物驱后水淹层测井解释难度大的问题，以地质、测井、生产动态等资料为基础，以开发地质、开发测井理论为指导，利用对子井分析技术，分析了不同开发阶段测井响应的宏观变化规律；通过岩电实验，在动态资料的约束下，建立了水淹层定量测井解释模型。将孤东油田八区12口新井15个层投产的解释结果与前人的解释结果、地质规律及生产动态数据进行了比较，符合率由老模型的46．7％提高到80％。

Model of log interpretation of water-flooded zones after polymer flooding

For the purpose of solving the issues of difficult interpretation on log interpretation of the water-flooded zones after polymer flooding in old areas,the macroscopic variation rule of log response at different production stage is researched using analytical technology of two-pair wells analyzes according to the theory of development geology and production log after data analysis of geology,log and production performance.Quantitative log interpretation model of the water-flooded zones is set up controlled by dynamic information in lithologic-electronic experiment.The interpretation results of 15 brought-in layers in 12 new wells of No.8 district in Gudong Oilfield by the new models are compared with the former results,with the coincidence rate enhance from 46.7% of the old models to 80% now.
