| 摘 要： | 利用严格的Biot介质模型,针对阵列声波测井情况,建立了基于物理统计方法的利用斯通利波幅度衰减反演储层渗透率之线性化最小二乘反演模型。作为对方法可行性的检验,运用该方法对理论合成数据进行了处理,结果表明运用统计方法后反演渗透率的偏差变小,证明了方法的可行性。

| Abstract: | Using Biot model to describe the permeable formation around a borehole,a linear least-square method for inversion permeability from borehole Stoneley waves,attenuations is improved by introducing the physical statistic into choosing amplitude ratio for array acoustic logging data.In order to test probability of the improved method,the synthetic full waveforms are processed.The results show that it is a feasible method to evaluate the permeability because of the smaller relative error. |
