摘　　要：在地震数据野外采集过程中,保证大型复杂障碍区下资料的连续性历来是作业施工的难点。地震采集特殊观测系统设计是目前解决这些问题的主要技术手段,特观设计的优劣直接影响地震采集质量及成本,目前特观设计主要依靠技术人员的经验制定,可靠性与经济性无法保证。本文介绍了一款使用Python语言编译的地震数据采集特观设计优化程序,该程序基于贪心算法,结合计算机的高速运算的优势,为大型障碍区的地震数据采集特殊观测系统选择最优化的方案。将该程序应用于在内蒙古某煤矿的三维地震勘探项目中,结果显示,该程序提供的优化方案效果良好,叠加次数与面元覆盖均匀,保障了数据采集质量的同时节约了施工成本。结论表明,应用贪心算法的程序所做出的特观设计相较于其他软件和人工设计,具备更加良好的经济性与实用性,能够为地表复杂区地震数据采集工作提供更加有利的技术支撑。In the field acquisition of seismic data,it is often difficult to ensure the data continuity under large and complex obstacle areas.At present,the design of special observation system for seismic acquisition is the main technical means to solve these problems.The quality and cost of seismic acquisition are often affected by the quality of various designs.As the design of special observation system for seismic acquisition mainly depends on the experience of technicians,its reliability and economy cannot be guaranteed.This paper introduces a visual design optimization program of seismic data acquisition compiled in Python language.Based on greedy algorithm and integrating the advantages of high-speed computer computing to select the optimal scheme for the special observation system for seismic data acquisition in large obstacle areas,this program is applied to a 3D seismic exploration project in a coal mine in Inner Mongolia.The results show that the optimization scheme provided by the program has good effect,and the stacking times and bin coverage are uniform,which ensures the quality of data acquisition and saves the construction cost.The conclusion indicates that,compared with other softwares and manual designs,the special visual design optimization program of seismic data acquisition based on greedy algorithm is more economical and practical,and can provide more favorable technical support for seismic data acquisition in complex surface areas.
