摘要：

针对当前二维有线遥测地震仪采集道数少、勘探范围小的问题,以MPC8360作为交叉站核心处理器,提出基于MPC8360的交叉站系统解决方案,完成交叉站系统处理器模块、网络模块和FPGA采集模块设计,实现交叉站对测线的管理和数据的转发,从而为三维地震勘探奠定基础。测试结果表明:网络模块能够满足三维勘探对地震数据交换的要求,FPGA采集模块在正弦波采集过程中获得理想效果。最后进行三维地震勘探野外实验,反演的三维空间地层模型与现场的地下空区基本吻合,从而验证了交叉站能够满足三维地震勘探的需求。

Abstract: The currently existing 2D cable seismic acquisition system had the problems that the number of acquisition channel was less. Based on MPC8360, the authors developed a new scheme for the cross-station system. MPC8360 was used as the cross-station's core processor as well. This system completed the design of a module of cross-station system, including the processor module, network module, FPGA acquisition module and realized the management of measuring line and data forwarding by cross-station, which lays the foundation of 3D seismic exploration. Test result shows that the network module can meet the requirements of data exchange in the 3D seismic exploration and FPGA acquisition module achieves the desired effect in the process of the sine wave acquisition. Finally, the authors conducted the experiment of the 3D seismic exploration in the field and inverse the 3D Stratigraphic model which consistent with the empty area in the exploration site, which proves that the cross-station meet the need of 3D seismic exploration.
