| 摘 要： | 砂岩孔隙度和含泥量是影响波速的两个重要因素。研究它们之间关系具有重要意义，本文利用含有裂隙的有效弹性模量关系和泥与骨架的组合理论，建立一个模型，用来描述波速和孔隙度及泥质含量的关系，所得关系与实验结果基本吻合。

| Abstract: | Porosity and clay content in sandstone are two important factors affecting wave velocity. It is of importance to study the relations among them. In this paper,A model was built,based on the theory of effective elastic medium,to describe the relation among wave velocity,porosity and clay content in sandstones. The theritical relation fits well with existing results. |
