| 摘 要： | 在叠前地震资料中的面波,是影响地震资料信噪比和分辨率的主要因素.传统的压制面波的方法,都不可避免地存在一些缺陷.广义S变换可以将单道地震记录从时间域变换到时频域,使面波和有效波在时频域上明显分开,在时频域上切除面波后再反变换回时间域,即可达到去除面波的目的.这里通过广义S变换的方法去除叠前资料中的面波,对理论模型和实际...

| Abstract: | Surface wave is the main factor that affects signal to noise ratio and resolution in pre-stack seismic data.The traditional methods of suppression of the surface wave have some unavoidable defects.Generalized Stransform can transform the single-channel seismic records from the time domain to the time-frequency domain,make the surface wave and effective wave separated clearly in the time-frequency domain,cut the surface wave in the time-frequency domain then inverse transform back to the time domain we can r... |
