序贯高斯模拟法在鄂尔多斯盆地储层预测的应用

Application of sequential Guassian simulation in reservoir prediction of Ordos basin

用波阻抗反演进行储层预测己得到认可,但在实际应用中经常会发现仅用波阻抗反演有时难以识别储层。采用无格点序贯高斯模拟反演技术可以进行多种测井参数的反演,对这些测井参数的综合分析有助于更有效地识别储层。在实际工作中采用上述方法进行测井参数反演,并结合在工作中总结的测井参数数据分析处理方法,识别了常规波阻抗反演难以识别的储层,取得了较好的应用效果。

Although wave impedence inversion technology has been widely used,the technology used only is difficult to identify some reservoirs in practice.Therefore,the sequential Guassian simulation has been adopted to carry out the inversion of multiple logging parameters.The comprehensive analysis of these parameters can be helpful in better identifying reservoirs. In combination with the logging data analysis,the hard-to-identify reservoirs by conventional wave impedence has been identified and has achieved good results in application.
