伊朗地震采集项目中的地震采集技术
|
摘要
文中介绍了近年来BGP在执行伊朗地震采集项目中的地震采集技术,其中包括网络资源的免费使用、多种震源激发技术、灵活的观测系统设计、接收方法的改进等,取得了较好的效果:①通过使用免费的网络资源,不但在最短的时间内向甲方提出技术方案,而且实现了对项目运作的更精确评估,整体上改善了特观和变观设计的效果;②多种震源联合激发,改善了资料品质;③灵活的观测系统设计是在复杂地区保证资料品质的必要手段,同时还可获得更好的经济效益;④通过检波器埋置工具的开发,使资料品质不断提高,其中在山地区,检波器的埋置以保证检波器耦合好为原则。
The paper introduced the seismic acquisition techniques in finishing Iran seismic acquisition project in recent years, among which including charge-free usage of network resource, shooting by multiple sources, flexible geometry design and improvement of receiving method, achieving better results: ①the usage of charge-free network resource not only provides technical scheme to A Party in the shortest time, but also fulfills more precious appreciation to the project operation, improving the effect of special geometry and geometry variation in a whole; ②joint shooting by multiple sources improved data quality; ③flexible design of geometry is a necessary tool ensuring data quality in complex area while acquiring better economic benefit; ④the development of geophone-planting tool made the data quality have dramatic progress. The geophone plant in mountains area should follow the principle getting good coupling of geophone.
