以塔里木盆地塔河地区碳酸盐岩复杂介质为例,依据地层条件岩石声学参数的实验测试结果,获得下述认识:1)纵横波速度随围压的增大而增大,随温度的升高而降低;2)岩石的动弹模量随着围压的增加而增加,随着温度的增加而减小;3)纵横波的衰减随着围压的增加而减弱,随着温度的增加而增强。

Taking the complex media of carbonates in Tahe area, Tarim basin,as an example,and based on the experimental test results of rocks' acoustic parameters under formation conditions,the following understandings are obtained: 1) P-wave and S-wave velocities increase with increasing confining pressure but decrease with increasing temperature;2) the dynamic elastic modulus increases with increasing confining pressure but decreases with increasing temperature;3) the attenuations of P-waves and S-waves decrease with increasing confining pressure,and increase with increasing temperature.
