摘　　要：　静校正(包括剩余静校正)和叠前去噪是复杂地区资料处理的关键,当资料信噪比太低时,剩余静校正的计算可能得到不合理的解,因此,在剩余静校正之前,做好去噪处理是必要的。在新疆柴窝堡地区,应用τ-p变换去线性干扰与剩余静校正之间通过多次迭代,交替执行,与常规的叠前处理相比,既可进一步改善叠前去噪效果,又可进一步减少静校正量不合理的概率。The static corrections (including the residual static corrections) and the pre-stack noise suppression are the keys of the data processing in the complex area. The computation of the residual static corrections may get some illogical solutions in the too poor signal-to-noise ratio data. Therefore,it is essential to deal with the noise suppression effectively before the residual static corrections are computed. In Chaiwopu Area of Xinjiang Region,the multi-iterations are applied between the linear noise suppression in τ-p transform and the residual static correction when both of them are executed alternatively. Compared with the normal method of the pre-stack data processing,it can both improve the effects of noise attenuation further,and reduce the probability of generating the illogical values further in the estimation of the residual static.
