摘要
煤层具有低速度、低密度特征,煤层与其他岩性接触的界面是良好的波阻抗界面,可以形成强振幅反射波。煤层在常规及特殊地震剖面上都具有明显的反射特征。煤层的强透射损失对于煤层识别非常重要。
Coalbed is characterized by low-velocity and low-density. The interface between coalbed and other rocks is a fair acoustic impedance interface that can form strong-amplitude reflection. On conventional and special seismic sections,coalbed is characterized by distinct reflection. The strong transmission lost of coalbed is very important for distinguishing coalbed.
