【摘要】 三维观测系统优化设计是野外地震采集工作的一个重要环节,影响着后期地震资料采集处理解释的各个工作环节.因此,高质量的观测系统设计是地震勘探工作的关键,然而在无限制的追求高信噪比、高分辨率的地震资料,高难度的野外施工的同时,这往往会带来较大的成本投入.鉴于以上存在的问题,文章着重分析质量最优和成本最优的观测系统设计,通过寻找观测系统参数与采集质量和采集成本的关系,结合二者的优点,提出了最优性价比的观测系统优化设计方法,并通过一个实际工区的试验,体现出该方法的应用效果,为高质量的观测系统设计提供新的思路和方法.更多还原

【Abstract】 3-D geometry optimization design is important part of field seismic acquisition work,which has influence on post-seismic data acquisition,processing and interpretation of the various working aspects.Thus,high-quality geometry design is the key to seismic survey.However the unrestricted pursuit of high signal to noise ratio,high resolution seismic data,and highly difficult field work at the same time often brings greater cost inputs.In view of the above problems,the article focuses on analyses of quality-optimal and cost-optimal geometry design.By looking for the relationship between geometry parameters and acquisition quality and acquisition costs,combining the advantages each other,we propose the best cost-effective geometry optimization design method,and through an experiment of the actual work area,we show the application effect of this method,which offers new ideas and methods to high-quality geometry design.更多还原
