在干砂岩超声速度资料上所进行的观测与有效压力的速度变化有关,也与在一个有效压力下预测岩石速度的能力有关。我们发现:弹性模量和速度对有效水压应力的敏感性随孔隙的减小而增加。特别地,
The observations made on the ultrasound data of dry sandstone are related to changes in velocity of effective pressure and also to the ability to predict rock velocity at an effective pressure. We found that the sensitivity of elastic modulus and velocity to effective hydrostatic stress increases with decreasing porosity. In particular,
