摘　　要：常规提高地震资料分辨率处理技术不能更好地满足实际生产需求。本文把Ricker子波引入到地震数据处理中,提出一种新的地震资料高分辨率处理方法。频率域宽带Ricker子波整形反褶积与其他常规方法不同之处在于期望输出为宽带Ricker子波。该期望输出具有主瓣窄旁瓣幅度较小,通过调整宽带子波的谱的参数,可以获得较高的分辨率。使用该方法在中牟地区页岩气地震勘探资料处理中取得了不错的效果。The traditional processing technology to improve seismic data resolution can not meet the requirements of real production,so a new high resolution processing technology based on Ricker wavelet is introduced in this paper.The broadband Ricker wavelet shaping deconvolution in frequency domain is designed to be the desired output,which is different from other deconvolution method.In this paper,the broadband wavelet was used to abtain the high resolution by adjusting the cutoff frequencies of the broadband wavelet because of its narrow main lobe and small side lobe.This method was applied to seismic data processing for shale gas exploration in Zhongmou area,Henan and the results are obvious.
