摘要

依靠常规的有线设备进行大三维或超大三维地震数据的传输非常困难甚至无法实现,而且设备投入大,施工效率低。基于网络传输技术的无线单点检波器用于高密度三维地震数据采集具有采集能力强、采集投入低、采集设计方便、施工效率高等优势。介绍了单点高密度采集的方法、优势和数据传输方面存在的问题,讨论了短程和远程通讯及数据传输等地震采集关键技术,列举了无线采集技术的现状并展望了未来无线采集装备和技术的发展趋势,给出了无线单点检波器在三维地震资料采集中的应用实例。
Because of the formidable equipment investment and low operational efficiency,it is nearly impossible to perform data acquisition of gigantic quantity of channels using the cable connected data acquisition system.Wireless point receiver acquisition technique which is based on single receiver with GPS equipped will provide geophysicists with the ability to customize survey designs for specific subsurface imaging targets at any depth and high density wide azimuth survey with smaller bin size.In addition to delivering improved image quality,this technology is also promising to improve the productivity of land acquisition operations.This paper reviewed the methods of high density acquisition with single point receivers,discussed the key techniques of data transmission in short and long ranges,and pointed out the outlook of the single point receiver data acquisition technology.A case history of single receiver data acquisition was also given.
