反褶积分层解释法的原理是,把测量所得的放射性测井曲线看作是放射性元素含量曲线经过一系列低通滤波器后的必然结果(图1)。因此有可能研究出合适的反数字滤波器(反褶积)。放射性测井曲线经过反数字滤波器后就可以近似地获得放射性元素含量随深度的变化曲线。J.G.Conaway推导出了三点式反运算子,使这一问題获得了比较简便的解决途径, The principle of deconvolution stratified interpretation is that the measured radioactive log is treated as a corollary of a series of low-pass filters after a radioactive elemental content curve (Figure 1). It is therefore possible to develop a suitable anti-digital filter (deconvolution). After the radioactive logging curve passes the anti-digital filter, the variation curve of radioactive element content with depth can be obtained approximately. J.G.Conaway derived a three-point inverse operator, so that this problem has been relatively easy to solve,
