用密度声波时差和自然伽玛测井曲线计算分散泥质结构泥质含量

Calculation of Shaly Content In the Dispersed Shaly Structure from Density, Acoustic Transit Time and Gamma Ray Logs

本文基于实验得到的有关分散泥质、结构泥质对声波波速的影响,用作者在理论上得到的、能反映这些影响的泥质砂岩的纵波波速公式;结合密度、自然伽玛测井曲线,给出了一种泥质砂岩中的分散泥质、结构泥质含量的计算方法。

This paper illustrates an approach to calculate dispersed and structural shaly contents in shaly sandstones, based on the effect of dispersed and structural shaly on acoustic velocity. This approach utilizes the equition of compressionel wave velocity derived theoretically by author which can reflect this effect, in combination with density, Gamma Ray logs.
