| 摘 要： | 近年来,三维叠前深度偏移地震资料处理技术得到了一定的发展,但是由于三维叠前深度偏移处理计算量大,要求有精确的深度-层速度模型,一直未走向工业化生产阶段.本文是在具备大型计算机的基础上,着重对如何求取精确的深度-层速度模型进行了探讨,提出了三维层速度相干反演和三维深度-层速度模型的优化处理方法. |
| 关 键 词： | 三维叠前深度偏移 层速度相干反演 模型优化 |

| Abstract: | Some advances have been made in recent years in the technique for processing three dimensional depth migration before stack. Nevertheless, as the amount of calculation work for this technique is very great and the precise depth interval velocity is required, the technique fails to attain the objective of large scale applicatio. On the basis of applying large scale computer, this paper deals emphatically with the formulation of the model for precise depth interval velocity and suggests the coherent inversion of three dimensional intervl velocity and the optimization of the model for dimensional depth interval velocity. |
| Keywords: | three dimensional depth migration before stack coherent inversion of interval velocity optimization |
