摘　　要：分析了鄂西—渝东地区地震勘探中目前利用偏移剖面转换深度剖面,然后用深度剖面直接编制构造图的方法,指出其存在工作量大,在高陡构造陡带部位效果差,与钻井误差较大的缺点,以及速度谱资料变速成图方法不适合本工区的原因,提出利用分层平均速度曲线进行分区成图的方法。理论分析和应用实例表明:该方法具有效率高、成图误差小的优点。This paper presents a method for seismic exploration in the Western Hubei-Eastern Chongqing Area, that is, a migrated profile is transformed into a depth section, which is directly used to structural mapping. But this method has some shortages, such as a large quantity of work, poor results in steep tilting positions of steep tilting structures, as well as great discrepancies from drilling. It is indicated that the velocity-variant mapping using velocity spectrum data is unfit for the study area, in stead, mapping using average velocity curves of horizons are of high-efficiency, with few errors, as indicated by theoretical analysis and case study.
