摘要

这里讨论了川西深层海相地震勘探工程设计的参数论证问题。在分析该区以往地震勘探工程设计的基础上,以现有地质认识为基础构建正演模型,利用Tesseral软件的正演模拟分析功能,进行地震采集参数的论证和观测系统的优化设计。地震数据采集实验结果表明,经过正演模拟优化的观测系统,能大幅度地改善地震数据采集的品质。
In the marine exploration of the western Sichuan, the geological models of the area were built by combining the geological understanding. On the basis of the previous exploration engineering designs, seismic acquisition parameters and optimizes geometry were designed by utilizing the Tesseral 2-D full wavefield wave equation for forward calculation. The acquisition data demonstrated that desirable geological results had been achieved. At the end of the paper, in order to provid some good references to the future marine exploration of this region, some suggestions were given by evaluating adaptability of the acquisition method.
