摘　　要：地震道积分是一项利用转换的相对速度剖面进行地层分析的技术,而GLOG 技术则是利用波阻抗剖面分析地层的。这两种技术的处理效果,总的来说是相近的,但是前者更能反映高速砂层的细微变化,而且砂层的标定精度高、直观,标定方法简单。经过标定的地震道积分剖面可以替代“连井油藏剖面”。可见,地震道积分技术在地震地层解释中是一项有发展潜力的技术。本文详细介绍利用这项技术解释埕岛油田砂体的方法,获得了令人满意的效果。Seismic trace integral is a formation analysis technique using converted relative-velocity section.GLOG technique analyses formations by using wave-impedance section.Generally speaking,the proces- sing effects of the two techniques are similar.However,the for- mer's processing result shows the fine variation of high-velocity sand bed,and gives visual and accurate delineated sand bed by using simple method.The trace-integral section whose horizons are delineated fun- ctions as the seismic section that includes reservoir and connects we- lls.It is obvious that seismic-trace integral is a very potential tech- nique for seismic stratigraphic interpretation.It is minutely described how the sand body in Chengdao oil field is interpreted by using this technique,Satisfactory result has been obtained.
