摘　　要：随着海上已发现油气田陆续进入开发和生产阶段,对于地震资料品质的要求也越来越高。从传统宽方位施工方式出发,结合该区实际地质条件和目前装备技术现状,通过对采集航次和震源船配置关系的改变,设计出满足地质需求的多船宽方位观测系统。在实际采集的过程中,考虑到海上平台的影响,又采取变观措施对原观测系统无法实施的测线进行了补充,最终形成了一套针对海上开发区的多船宽方位地震采集观测系统设计方法,对类似地区的作业具有借鉴意义。With the offshore oil and gas fields entering development and production stage, the require- ment to the seismic quality becomes higher. Based on conventional wide-azimuth observation system, considering the geologieal boundary eonditions and equipment situation, new wide-azimuth observation system was designed by changing the navigation number and vessel deployment. In the seismic acquisition, to solve the platform influence, geometry-variable design was applied as a supplement. All the results above formed the wide-azimuth observation system technique series for the offshore production zone. The method may be used as a reference to similar areas.
