| 摘 要： | 利用人造岩样，对地层的弹性模量、泊松比、抗压强度等参数随含水饱和度的变化规律进行了实验研究，并摸索出了从岩样制备到实验方案确定的适合于松散砂岩力学性能测试的一整套方法。研究表明：疏松砂岩的弹性模量很小；随着含水饱和度的增大，弹性模量减小，泊松比的变化规律不太明显；随着含水量的增大，岩样的三轴强度下降，含水饱和度对弱胶结岩石强度的影响比对胶结较好的地层敏感。

| Abstract: | Using artificial rock sample, the variation law of the effect of the water content on the rock mechanical parameters, such as elastic modulus, Poisson ratio, compressive strength, is experimentally studied in this paper. A set of method to test the mechanical property of the unconsolidated sandstone is also developed. The study shows that the elastic modulus of the unconsolidated rock is very low. And the elastic modulus and tri axial strength decreases with the increase of the water content |

| Keywords: | water saturation sandstone modulus of elasticity poissons ratio compressive strength sand control lab test |
