| 摘 要： | 根据以细砂岩为主的２４５个岩样纵波传播速度及其多项岩石学参数的测试结果，建立了波速与有效孔隙率、中间粒度值、基质含量和胶结物含量等参数间的回归关系式。并通过波速与各单项参数间的相关程度分析，确定了有效孔隙率是影响纵波速度的最显著参数。

| Abstract: | The Propagation velocity of longitudinal waves was measured of 245 sandstone samples and by means of correlation and regression statistics. Its dependence on other petrographic parameters (i. e. , propagation velocity , effective porocity , median values of grain size distributions , matrix and cement contents) was investigated.The analysis of the dependence of velocity on each petrographic parameter shows that the influence of effective porocity on propagation velocity is the most significant. |

| Keywords: | petrologic parameter sandstone longitudinal wave velocity effective porocity regression equation. |
