Zusammenfassung:The invention discloses a shale gas reservoir Young modulus determination method and device based on element logging. The method comprises the steps that on the basis of the mineral content, the rock porosity, the TOC content, the water saturation, the rock skeleton density and the rock density, determined according to element logging data, in shale gas reservoir rock, the rock skeleton longitudinal and transverse wave speed and the rock longitudinal and transverse wave speed of the shale gas reservoir rock are sequentially determined through a volume model method; according to the rock skeleton longitudinal and transverse wave velocity, the rock longitudinal and transverse wave velocity, the rock skeleton density and the rock density, the rock skeleton Young modulus and the rock Young modulus are determined respectively. According to the method, the dynamic Young modulus of the rock skeleton and the rock can be quickly and accurately determined by using the element logging data. 本发明公开了一种基于元素录井的页岩气储层杨氏模量确定方法和
