摘　　要：在地震勘探中,可以使用最小平方反滤波来提高地震资料的分辨率。但是,在最小平方反滤的过程和其输出的地震道中,高频的成份有时会过多而难以解释。在反滤波输入道中加入一定的白噪声,可使反滤波效果更好,同时对地震资料进行能量保持处理,这些都会对地震资料的处理有很好的效果。根据以上原理,开发了一套较完整的最小平方反滤波处理的软件,对叠后的地震资料进行了处理,实验结果表明本软件在提高地震资料分辨率的同时,保持了较高的信噪比,也减少了计算反滤波因子时的误差。In the seismic exploration, the least square inverse filtering can be used to enhance the resolution of seismic data. However, in the process of least square filter, the high frequency component is sometimes difficult to explain too much in the out-put of seismic trace.If we add certain white noise in the inverse filtering input way, the effect of the inverse filtering can become better, and the seismic data can also be made energy to keep at the same time.According to the above principle, we developed a set of relatively complete least square inverse filtering processing software , and dealed with the processing of post-stack seismic da-ta.The experimental results show that the software improves seismic data resolution , maintains a high signal-to-noise ratio, and also reduces the calculation error of inverse filtering factor .
