在塔河油田联片地震资料解释过程中，地震子波非零相位化造成的“伴随相位”假象很容易被当成有效反射加以解释。
During the processing of seismic data interpretation of Tahe Oilfield, pseudomorphism of adjoint phase caused by non zero phase wavelet was easily interpreted as effective reflection.
该现象可以用高斯光束通过介质时产生的空间自相位调制解释。
This phenomenon can be explained by the spatial self-phase modulation of the Gaussian beam passing through the nonlinear medium.
应用表明，研究区内90?相位地震资料使振幅与岩性测井曲线形成了较好的对应关系，且提高了解释精度；
The results show seismic amplitudes can be correlated to log lithologies and the interpretation accuracy can be improved by using 90?phase seismic data.
