| 摘 要： | 基于野外"点源"观测数据的常规深度偏移等复杂叠前处理方法涉及到巨大的计算量。Berkhout基于"面源"的面炮技术提供了高效精确的波动方程叠前深度成像的有利选择。本文拓展了Berkhout面炮技术,提出了高效精确的基于波动方程的曲面波技术,给出了曲面波合成算子的普适性数学表达式,并发展了面向目标的曲面波地表控制照明技术。其能够对复杂地质构造进行高效高质量成像。理论模型与实际资料的数值计算给出了很好的成像结果。

| Abstract: | The prestack processing methods, such as conventional depth migration based on the data observed at field "spot source", is related to great calculated amount. Berkhout areal shot technique based on "areal source" makes profitable choice of effective and accurate wave equation prestack depth imaging. The Berkhout areal shot technique is developed, curve wave technique based on wave equation and adaptable math expression of curve wave composite operator are provided, and target-oriented surface control lighting is developed. It is able to image complicated geologic structures accurately. A good imaging result is provided after the model data and real data are calculated. |
