常规二维滤波方法难以消除复杂地表区弯曲测线地震记录中的浅层干扰。本文从分析地震记录中初至波和有效波时距曲线的形态出发，提出了将初至波校直的去噪方法。通过对实际资料的应用，结果表明该方法对消除弯线炮记录中的浅层干扰具有良好的效果。
The conventional two-dimensional filtering method can hardly eliminate the shallow interference in the seismic record of the curved surface of complex surface area. Based on the analysis of the shape of the first arrival wave and the effective wave time-distance curve in the seismogram, this paper proposes a denoising method to align the first arrival wave. Through the application of the actual data, the results show that the method has a good effect on eliminating the shallow interference in the record of the curved line gun.
