全波场正演模拟技术在ZBTD区块的应用与分析
|
摘要
在复杂地表条件下的地震资料处理中,正确识别和应用各种波非常重要。应用全波场正演模拟技术,可以在地震资料处理中数值模拟实际资料的理论模型,从而分析各种波在地层中的传播规律,利用波场快照识别有效波和干扰波。全波场正演模拟可将看不到,摸不着的波场,形象地展现出来,有助于观察地质结构与地震反射同相轴之间的因果联系。全波场正演模拟成为地质和地球物理学家之间实现相互理解和达成共识的最有效的工具。
It is important to correctly distinguish and apply various waves in processing seismic data from complex subsurface.Full-wave forward modeling technique can be used to numerically simulate theoretical model of real data in the seismic data process in order to analyze various waves' spreading patterns in the layer and distinguish effective waves from interference ones with the help of wave-field snapshot.The technique can visualize the wave field to help observe causal relation between geologic structure and seismic reflection lineups.Therefore,it becomes the most effective way to help geologists and geophysicists understand each other and reach an agreement.
