摘　　要：Klseis软件系统及其三维观测子系统设计软件在三维地震勘探设计方面具有强大的功能,特别是在山地、水网、城镇、沙漠等各种复杂地表条件下的三维地震观测系统设计中,其灵活的特殊观测系统设计,为提高叠加次数,确保勘探区内工覆盖次数,满足勘探设计要求提供了保障。以淮北矿区某三维地震勘探为例,详细介绍了该软件的使用方法及步骤,并对复杂地形图的导入及格式转换进行了说明;针对该区大村庄或者河道较宽造成的设计不当形成的"天窗"问题,提出了添加激发点或调整炮检点关系的方法,以确保覆盖次数满足设计要求;此外,对于区内个别特别复杂地形,建议利用Klseis软件的块状观测系统设计,以弥补规则观测系统的不足。实例表明Klseis软件系统在复杂地区,可有效提高工作效率,保证野外施工质量。The Klseis system and its 3D observation subsystem design software has powerful serviceability in 3D seismic prospecting design, especially in mountainous area, web of criss-erossed water courses, cities and towns, desert regions 3D seismic field setup design. Its flexible special observation system design provides assurance on stacking fold, number of coverage in prospecting area. To take one 3D seismic prospecting in the Huaibei mining area as an example, introduced usage method and steps of the software in detail, and explained lead-in and format conversion of complex topographic maps. In allusion to ＂dormer window＂ caused by inappropriate design in large village and broad river channel areas, advanced methods of to add shotpoint or regulate shot-detector relations to guarantee designed coverage number. Besides, for ad hoc complex topography, to use block observation system design of Klseis system is advised to make-up deficiency from regular observation system. Examples have demonstrated that to use Klseis system in complex areas can improve operation efficiency effectively and ensure field operation quality.
