【摘要】 讨论一种根据3D 地震数据计算地层横向变化的方法——动态波形匹配方法．该方法利用动态规划算法对相邻地震道地震波形进行动态波形匹配并计算波形匹配费用．把波形匹配费用作为相邻地震道地震波形之间差异大小程度的度量．对大庆油田一块800 km~2的3D 地震数据的计算表明，动态波形匹配费用可以较好地度量相邻地震道地震波形之间的差异，表示地下地质体的横向变化，如断层、裂缝发育带和火山岩岩体等．更多还原

【Abstract】 A method of the lateral predication from 3-D seismic data is discussed using Dynamic Waveform Matching(DWM).The method uses Dynamic Programming algorithm to match the adjacent seismic traces and calculate thewaveform matching cost.Using the cost to represent the discrepancy of the adjacent seismic waveforms.We calculat-ed the 3-D seismic data about 800 square-kilometers in Daqing Oil Field.It is shown that the DWM cost can preferablymeasure the discrepancy of the adjacent seismic waveforms,and the underground geologic body’s horizontal variety,such as faulting,fissure and eruptive bodies,etc.更多还原
