摘　　要：针对测井中信号传输速度低、操作繁琐等问题,提出一种高速数据采集与传输的新方法。该设计系统采用高速AD转换,以灵活、高效性价比FPGA芯片-EP1C6为平台,利用USB传输,实现了基于Verilog的声幅测井系统。最终,在上位机得到的声幅测井曲线用来判断固井质量。在水泥胶结良好时,固井声幅测井值低;水泥胶结差时,固井声幅测井值高。In view of the fact that in logging in the signal transmission speed is low and that the operation is complicated,this paper presents a new method for high-speed data acquisition and transfer.The newly designed system uses the high-speed AD converter.It uses a flexible,cost-efficient FPGA chip,EP1C6,as a platform and uses USB transfer to achieve a sound piece logging system based on Verilog.In the end,the sound amplitude obtained from the host computer is used to determine the quality of cementing.If the cement bond is good,the cementing sound amplitude log value is low;for poor cement bond,the cementing sound amplitude log value is high
