|
摘要
矿产资源勘探尤其是金属矿勘探具有地质条件复杂、勘探深度大、分辨率要求高等特点.常规地震勘探技术与装备难以满足复杂地形高精度三维地震勘探需求.针对该技术难题,研发一套高保真、高分辨率轻便分布式混合遥测地震勘探系统迫在眉睫.鉴于此本文开发了信号高保真高分辨率数据采集技术、实时通讯及采集单元无址链接技术和多媒介混合遥测技术等一系列关键技术.成功研制出SE863单站单道分布式混合遥测地震数据采集系统,该系统由31位高分辨率采集单元链、集3G/4G无线通讯及有线通讯的交叉数据管理站、便携式主控站以及测控软件组成.支持二维、三维高密度地震反射波勘探、散射成像、天然源透射成像等地震数据采集工作.利用该套系统与428XL地震数据采集系统进行同步对比,并将该系统交付第三方使用完成了1km~2三维地震勘探实验,结果表明该系统设备轻便、性能稳定、分辨率高、数据质量好,是我国具有完全自主知识产权的高精度轻便分布式地震勘探技术装备,大大增强了我国地震勘探技术核心竞争力.
Seismic exploration is characterized by complex geological conditions,large exploration depth and high-resolution requirement.Conventional seismic exploration techniques and equipment used in oil and gas exploration are difficult to meet the needs of metallic ore exploration.To solve this problem,aportable distributed telemetry seismic exploration system(named SE863)is developed.A series of key technologies are studied,such as high fidelity and high resolution data acquisition,real time communication and unaddressable link of acquisition units and multi-media hybrid telemetry measurement.The system consists of a 31-bit high-resolution acquisition unit chain,3 G/4 Gwireless communication and wired communication cross-data management station,aportable main control station,and a set of software.Comparing with the 428 XL seismic exploration system of Sercel and the test in 1 km~2 3 Dseismic exploration show that this system has advantages of light equipment,stable performance,high resolution and good quality of data.It enhances the core competitiveness of seismic exploration technology of our country.
