约束地震反演中测井数据的标准化及储层的精细标定
|
摘要
约束地震反演结果是否合理、准确,很大程度上取决于基础工作。测井数据标准化处理和储层精细标定是约束地震反演基础工作的核心。文中通过实例说明了测井数据做标准化编辑处理与不做标准化编辑处理对反演结果的影响,前者储层精细标定的结果准确,后者效果很差。文中简要地介绍了参与约束地震反演的测井数据标准化编辑处理和储层精细标定的方法。
Whether the constrained seismic inversion is correct and accurate that depends on basic work in a great degree.Standard processing of logging data and fine labeling of reservoir are the kernels of basic works of constrained seismic inversion.It is shown by the practical cases in the paper the influence of logging data that has been processed by standard edit or has not been processed by standard edit on inversion results,the former resulted in accurate labeling of reservoir and the later has poor results.The paper briefly introduced the methods for standard edit processing of logging data in constrained seismic inversion and fine labeling of reservoir.
