摘　　要：设计了一种基于动态3D油藏地质模型的新型测井分析平台,该平台将传统的油藏描述、专家系统和知识库进行有机融合,可改变传统的测井分析模式。具体包括:(1)利用地震成果资料和区域测井资料自动构建3D油藏地质模型,且根据需要自动生成平面图件,以使解释人员全面掌握目标井所在的区域信息,为解释人员提供感性认识;(2)通过邻井自动对比技术自动生成目标井成果,为分析人员提供初步的解释结果;(3)测井分析家在此基础上进行精细化测井分析;(4)系统依据分析结果自动更新区域3D地质模型,为下一口井解释提供参考。由于3D模型直观地反映地层特性、地层分布特征、油气分布状态等,能够使测井分析家更好地把握目标层特性,提高解释符合率。最后验证了该技术方案的可行性。A logging analysis platform based on 3D reservoir geological model was developed,and it can combine the traditional reservoir description,the expert system and knowledge base. The logging analysis platform changes the traditional logging analysis method.Specific logging analysis steps include：（1） to automatically build a preliminary 3D reservoir geological model based on seismic data and regional logging data,and to automatically generate plane maps according to need so that the interpreter can fully grasp the regional information of the target well and the perceptual knowledge is provided to the interpreter;（2） to automatically generate the result of target well by the automatic contrast of adjacent wells so as to provide the preliminary interpretation result for analyst;（3） then the analyst to finish fine logging analysis based on the preliminary interpretation result;（4） according to the fine analysis result,the platform system to automatically update regional 3D reservoir geological model,which provides a reference for the interpretation of next well. The 3D reservoir geological model can directly reflect the stratum characteristics,stratigraphy distribution features and hydrocarbon distribution state. The field application of the logging analysis platform shows that the technical scheme is feasible.
