摘要
利用零偏VSP初至波在不同接收点频谱绝对值，展示了井所在地区地震波在地下的传播规律。根据各测点初至波频率、振幅的变化情况得出地层对地震波的吸收规律，并且利用初至波的分频曲线求得地层品质因数Q值。
The laws of seismic wave propagation in the subsurface and seismic wave attenuation bystrata are studied by using the absolute value of frequency spectrum along with the vanations of frequencyand amplitude for zero-offset VSP first arrivals at different receiving point. Using the lrequency-divisioncurve of first arrivals, the quality factor of strata is also derived.
