摘要
常规的反演方法是对感应测井资料进行线性反褶积。由于感应测井获得的响应曲线是地层非线性时变滤波的结果，所以，感应测井响应可随地层电导率发生非线性变化。用相量反褶积方法分别设计出实部信号和虚部信号所对应的反滤波因子，对反映测井响应随电导率非线性变化的非线性函数进行了拟合，用设计出的滤波因子及被拟合出的非线性函数对模拟相量感应测井资料进行了相量反褶积。处理结果表明。
The traditional inversion is the linear deconvolution for induction log data. The
induction log response can be nonlinearly changed because of nonlinear and timevariable filter.
This paper presents a method of phasor processing deconvolution. The inversion filter factors
corresponding to inphase and quadrature signals are designed by the method of phasor
processing deconvolution, and then linear functions are fitted to accommodate nonlinear
toolresponse. The phasor deconvolution of the simulated induction log proves that the shoulder
effect and skin effect can be substantively eliminated.
