摘　　要：地震资料处理中反褶积参数的选择主要依赖处理人员的经验,缺乏一种定量分析方法对反褶积效果做科学评价。传统井控反褶积参数定量分析方法主要使用VSP走廊叠加数据做质量控制,但在煤田地震勘探中VSP探测罕有应用,这限制了井控反褶积质控方法的在煤炭领域的应用。采用测井数据制作合成地震记录,将其与井旁道求取相关系数,依据相关系数对反褶积参数进行评价,实现对反褶积参数定量质控。该方法在沁水盆地应用表明,利用定量分析方法可以有效质控反褶积效果。The selection of deconvolution parameters in seismic data processing mainly relies on the experience of processing personnel,lacking of a quantitative analysis method for scientifically evaluating the deconvolution effect.The quantitative analysis method of wellcontrolled deconvolution parameters mainly relies on VSP corridor stacking data for quality control.However,VSP detection is rarely applied in coal seismic exploration,which greatly limits the application of well control deconvolution quality control methods in the coal field.This article uses logging data to produce synthetic seismic records,calculates correlation coefficients with well side channels,and evaluates deconvolution parameters using correlation coefficients to achieve quantitative analysis.Application of this method in the Qinshui Basin shows that using quantitative analysis method can effectively improve deconvolution effects.
