摘要
针对三维地震资料处理,尤其是三维叠前深度偏移处理,提出一套交互三维速度模型建立方法,并在工作站上设计与实现了这套交互三维速度模型建立系统。该系统可按交互方式进行叠加速度、偏移速度和层速度分析,有效地建立三维层位结构和速度模型,实现三维模型的可视化,提高速度模型精度,在实际的三维资料处理中效果良好。
An interactive method of building 3 D velocity model is put forward according to 3 D seismic data processing , especially 3 D prestack depth migration,and the software system of building the 3 D interactive velocity model is designed and brought about on the workstation. The system can analyze interactively the stack velocity, migration velocity and interval velocity, build efficiently the 3 D layer structure and velocity model, realize the visualization of 3 D model and improve the accurate of the velocity model. A satisfactory result has been obtained in the 3 D real data processing.
