摘　　要：利用野外测量的露头资料,结合邻区钻测井数据,制作模拟地震合成记录,对穿过Garmsar区块Kuh-e-Gugird背斜的地震资料进行地震层位标定,从而建立地质与地震之间的纽带。通过反复实践,并将所得结果与邻区利用常规方法,即测井资料获得的合成记录标定的情况进行对比与验证,结果表明,二者能较好地吻合起来,该方法对缺少钻测井资料的新区地震资料解释具有较好的应用价值。We make the synthetic seismograms from field outcrop data and references to the drilling and well-logging data of the adjacent area. The synthetic seismograms can be applied to identify seismic horizon, thereby the relation between geological data and seismic data was established in Kuh-e-Gugird anticline of Garmsar block. Compared our results with the marking horizons of adjacent area based on conventional synthetic seismograms, the two results were able to reach agreement. This method is useful to the seismic interpretation of the new area which lacks drilling and logging data.
