摘　　要：村庄作为大型障碍区在地震数据采集施工过程中往往会成为整个工区的施工难点。为解决这些难点问题,对地震采集观测系统进行特殊观测系统设计是唯一有效的技术途径。项目的地震数据采集质量和采集成本与特殊观测系统的设计的优劣息息相关。这里使用基于贪心算法的特殊观测系统优化设计程序,在测试工区对大型村庄障碍区和浅层地震地质条件运用了不同测线方位角的交叠观测系统设计。在村庄等具备不同测线方位角的观测系统布设条件的大型障碍区,使用优化合理、经济适用的特观设计做出了初步尝试,为野外地震数据采集工作的降本增效提供了有利的技术支持。As a large obstacle area,villages often become the construction difficulty of the whole working area in seismic data collection.The only effective technical way to solve these complex problems is to design a unique observation system for the seismic acquisition and observation system.The quality and cost of the seismic data collection of the project are closely related to the design of the particular observation system.This paper uses the particular observation system based on the greedy algorithm to optimize the overlapping observation system design for the large village obstacle area and the shallow seismic geological conditions.Setting the conditions of observation systems with different azimuth angles of measurement lines in villages In large obstacle areas,a preliminary attempt is made to use the optimized,reasonable,and economical special view design,which provides favorable technical support for the cost reduction and efficiency increase of field seismic data collection.
