可以利用弥散曲线和人工合成记录来检验过井测量中导波的理论特性。模拟和野外观测证实,在许多地震测量中占优势的能量是导波(也就是体波)形式传播的,这些能量与一个界面有关,或与一组综合界面有关,只要井间存在具有明显速度差的连续界面。这些模型解的弥散与波形中含有层间构造信息,特别是在波导中部充满流体的平行应力构造。因为通过选择频率、震源类型,以及两井中震源和接收点的位置,在一定的程度上可以控制这一信息含量,井间
Dispersion curves and synthetic records can be used to verify the theoretical properties of guided waves in over-well measurements. Simulations and field observations confirm that the dominant energy in many seismic surveys is propagated in the form of guided waves (ie, body waves) that are associated with an interface or with a set of integrated interfaces as long as there is a clear velocity Poor continuous interface. The dispersion and the waveforms of these models contain information about the interlayer structure, especially the parallel stress structures filled with fluid in the middle of the waveguide. Because this information content can be controlled to a certain degree by choosing the frequency, source type, and the location of the source and receiving points in both wells,
