利用密度测井计算孔隙度

Calculate Porosity by Density Logging

介绍利用密度测井的原理及电子密度eρ与真体密度ρb有线性关系进行岩层孔隙度计算,确定岩层的孔隙度。对于了解岩层的含水、含气及定量解释含水层和气层提供依据。

Using the principles of density logging, and the linear relation between electron density ρe and bulk density ρb to calculate the rock porosity and determine the porosity of rock are introduced, which provides a basis for learn about the rock water- bearing, gas- bearing, and their quantitative interpretation.
