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.
