摘　　要：将模式识别技术应用于自动追踪地震剖面同相轴．追踪过程用迭代法来实现，第一次迭代时追踪到强同相轴，在其后的迭代中追踪到弱同相轴．每次迭代中的追踪范围限制在前一次迭代已得到同相轴所勾划出的区域内，采用相关相邻地震道的方法追踪同相轴，一种称为双态相容性检测法ＢＣＣ的算法可以同时相关三个道．追踪完同相轴后自动编辑同相轴，提供描述同相轴的有关参数．迭代法和ＢＣＣ算法的结合在模拟人工解释以及将“地质趋势”加入最终结果方面是有效的．Pattern recognition is applied to automatically tracting seismic profile events.Iteration method is used in the process of tracking. Strong events are tracked in first iteration and in later iterations,weaker events are tracked. Each iteration is confined within the areas delineated by the events tracked in last iteration.By correlating neighboring seismic traces,the events are tracked.An algorithm called binary consistency checking (BCC) can correlate three traces at the same time. After the events are tracked,they are automatically edited,and the relative parameters for describing events are presented. The combination of iteration with BCC algorithm is effective in simulating manual interpretation and incorporating geologic trend into the final result.
