地震采集观测系统的构建与优选
|
摘要
通过对采集参数分类,提出了候选观测系统全集的构建方法,建立了综合考虑均匀性、相似性、横纵比、采集成本等因素的定量观测系统评价法则,确立了观测系统定量优化的最佳流程,为观测系统设计提供了新的思路与方法。通过在塔里木盆地WN区块的应用,最终优选出12线4炮320道观测系统,经野外采集论证效果良好,证实了方法的可行性。
A method to optimize acquisition geometry design is introduced among a few proposed acquisition layouts.By parameters grouping and analyzing,different acquisition designs can be established.Quantitative evaluation criteria for parameter factors,such as uniformity,similarity,aspect ratio,acquisition costs and other factors,are proposed.With a comprehensive consideration of these factors,geometry design could be optimized.The method shows its feasibility in the field.In an experiment in the WN Block,Tarim Basin,the optimized acquisition geometry for 12L320S320T is considers as the best geometry design based on parameter argument after the acquisition.
