煤系地层拟孔隙度测井曲线重构及应用

摘要

Based on the examples, this paper gives an explanation on the principle and method of application of gamma - gamma logging curve and apparent resistivity logging curves to reconstruction of apparent density and pseu- do porosity curves of the rock without density logging and porosity logging, which further lays a theoretical basis for the prediction of water abundance in coal seam roof and floor by applying the inversion of seismic multi - attribute pseudo porosity parameter.%通过具体实例,阐述了在没有进行岩石的密度测井及岩石孔隙度测井条件下,利用伽玛-伽玛测井曲线及视电阻率测井曲线进行岩石视密度及岩石视孔隙度曲线重构的原理及方法,为进一步利用地震多属性拟孔隙度参数反演预测煤层顶底板富水性奠定了理论基础。
