摘要传统有线地累采集仅器受带道能力(仪器主机外设最大激活道数及完成正常数据回收的能力)和施工便利性的限制,已不能满足当前健康、安全、环境保障及高效快速施工要求,故存储式无线节点地累采集仪应运而生,其独立自主的采集站工作模式大大缩减了有线仪器花费在建排列和查排列上的时间,且不涉及采集站与仪器之间的数据通讯,可以实现在线道数的任意扩展。该仪器适用于任何陆上施工环境,可配合“两宽一高”地震采集方法的推广应用,在海外某个复杂城区边的地震勘探项中,应用了OYOGeoSpace公司研发的存储式无线节点地累采集仪器(简称GSR)与Sercel公司的428XL有线地震采集仅器(简称 428XL)进行野外联合施工。通过系统介绍GSR的工作原理,分析了GSR与428XL联合应用中的数据一致性间题的产生原因,提出了解决方案,并介绍了现场数据处望的关键技术。结果表明:GSR与428XL的联合应用在复杂地表地震采集施工中达到采集成本和采集质量和谐统一的目的,资料品质获得了重大突破。

Abstract: Due to the restriction of channel capacity (the maximum active channels outside the host and the normal data recovery aasaasea efficient and fast operation. In this situation, the memory type wireless node seismic recorder emerges. With independent acquisition station, this recorder removes the time-consuming array construction and check procedures of traditional wire seismic recorder. It does not involve data communication between the acquisition station and the recorder, so the online channels can be extended randomly. This memory type wireless node seismic recorder is applicable to any onshore operation, and it can be used together with the "2W1H" seismic acquisition method. The memory type wireless node seismic recorder developed by OYO GeoSpace Company (GSR for short) and the 428XL wire seismic recorder of Sercel Company (428XL for short) were used jointly in the field seismic survey near a com-plex urban area abroad. In this paper, the working principle of GSR was introduced systematically. Then, the issues related to the consistency between GSR and 428XL during their joint application were analyzed, and the solutions were provided. Finally, key tech-nologies for field data processing were illustrated. It is indicated that the joint application of GRS and 428XL in seismic acquisition in complex surface areas guarantees the matching and consistency between acquisition cost and acquisition quality, and improves the data quality significantly.

伴随着地震采集技术的不断进步和地震采集仪器的推陈出新,在同一地震勘探项目中同时使用不同厂家不同型号的地震采集仪器不可避免"。GSR 节点地震仪(以下简称GSR)是美国OYOGeoSpace 公司投入研发的无线存储式节点仪器,由于存储式节点仪器不涉及采集站与仪器之间的数据通讯,故
可以实现在线道数的任意扩展,适用于任何陆上施工环境。采集站独立自主的工作模式大大缩减了有线仪器花费在建排列和查排列工序的时间,通过简化生产组织提高了施工效率,在城区等复杂地表施工作业的优势更加明显。
