利用常规测井确定岩石杨氏模量——以富县区块上古生界储层为例

Determination of Yong’s modulus by using conventional logging——Take upper Paleozoic reservoirs of Fuxian block as an example

岩石杨氏模量是制定压裂改造方案的重要参数,利用岩石三轴压缩实验和超声波实验测试资料,通过曲线拟合,得出了纵波时差与横波时差的关系式,并求出了动态杨氏模量、静态杨氏模量和体积密度三者关系式,建立了富县区块上古生界储层常规声波测井和密度测井下的静态杨氏模量数学模型。

Rock young's modulus is an important parameter on making fracturing reconstruction scheme. By using the rock true triaxial compression testing data and ultrasonic testing data, through curve fitting, the relation between longitudinal wave and transverse wave has been obtained. Besides that, the relation among the dynamic young's modulus, static young's modulus and bulk density has also been calculated. In the end, the mathematical model of static young's modulus under conventional acoustic logging and density logging from upper Paleozoic reservoirs of Fuxian block has been established.
