摘要
地震波通过含气层时高频能量将发生衰减,低频能量会出现增强现象,当岩石含天然气时,弹性波振幅衰减量显著增大,相对低频能量表现增强,而这些差异也为使用地球物理资料进行油气检测提供了依据。
High-frequency energy weakens when seismic wave energy passes through the gas layer,and the relative low-frequency energy increases.The amplitude decrement of the elastic wave increases significantly when the rock contains natural gas,while the relative low-frequency energy is enhanced,and these differences provide basis for the application of geophysical data in oil and gas testing.
