测量地震波垂直通过地层时的能量衰减,以往所做的工作只是局限于较厚的均匀各向同性物质。目前,已经在正常层状的墨西湾沿岸沉积地层中获得了有价值的结果。我们把覆盖地下一小区间深度上许多道的频谱相对炮点分别归一化之后,求其平均,以去掉反射干扰;并由 Measuring the energy attenuation of seismic waves vertically through the formation, the work that has been done in the past has been limited to thicker, homogeneous isotropic materials. At present, valuable results have been obtained in normal stratigraphic sedimentary formations along the Gulf of Mexico. We normalize the spectrum relative shot points of many channels covering the depth of a subterranean interval, and average them to eliminate the reflection interference.
