| Abstract: | 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 |
