井条件下的几何因子理论及反褶积滤波

THEORY OF DRILLING-BASED GEOMETRIC FACTORS AND DECONVOLUTION FILTERING

本文讨论用井条件下的几何因子设计反褶积滤波的方法。将这种方法用于自然电位(SP)曲线的计算,能够部分地消除围岩影响,提高地质参数的数据精度。

This paper deals with the way of designing deconvolution filtering using the drilling-based geometric factors. By applying this method to SP curve computing, the shoulder-bed effect could be,to some extent, removed so that the data accuracy of geologic parameter is enhanced as a matter of course.
