Attenuation of wave amplitude of reservoir rock at simulated high temperature and pressure is measured with spectrum-amplitude comparison mediod in laboratory.
在实验室内用频谱振幅比较法模拟测试了储集层岩石在高温高压下的弹性波振幅衰减值。

The technique makes use of dual energy X-ray imaging, where overlapping tissue signals can be isolated and quantified by exploiting the change in X-ray attenuationat different energies.
这项技术通过双能X-射线成像，重叠的组织信号可以被隔离，并利用不同能量的X射线的改变衰减量化。
