波动方程正演在地震采集设计中的应用
|
摘要
针对日益复杂的勘探采集对象,利用已有的地震、地质资料,结合地震反演建立合理的地下地质模型,运用波动方程正演技术设计地震采集观测系统,寻找最佳的采集方法。利用波动方程正演技术不仅可以提高解决复杂勘探目标采集的能力,而且能避免盲目试验的巨大浪费。通过对该项技术整个过程的介绍和研究,提出相应的技术要求、方法和对策。
Aiming at the complicated acquisition object,seismic wave forward techniques were used to design an observation system to seek for the optimal wave equation acquisition method,a geological model was built by using seismic inversion technology with seismic and geological data.Wave equation forward modeling not only could be used for enhancing the ability of solving the problem of complicated object collection,but also reducing the expense of eyeless test.Through the introduction and studying of the whole process of the technology,the corresponding requirement,method and countermeasures are proposed.
