摘　　要：针对传统测井电缆传输存在抗干扰能力差、传输速率低、传输距离短等问题,研究设计了一种基于现场可编程门阵列(FPGA)的测井信息光纤传输系统,将井下采集的视频和温度信息,通过光纤链路传输至井上。系统以FPGA为主控制器,并设计光纤链路,完成井下多种传感器数据的光纤传输系统的整体方案设计,最后对系统进行测试和功能验证。结果表明光纤通信系统通信及应用功能正常,验证了本测井信息光纤传输系统的可行性和有效性。Aiming at the problems of poor anti-interference ability,low transmission rate and short transmission distance in traditional logging cable transmission,an FPGA-based optical fiber transmission system for logging information is designed.The system collects downhole video,temperature and pressure information and transmits it to the well through optical fiber link.With FPGA as the main controller combined with optical fiber link transmission system,the overall scheme design of downhole information optical fiber transmission system for multiparameter measurement can be realized,and the system function test can be carried out.The results show that the communication and application functions of the optical fiber communication system are normal,and the feasibility and effectiveness of the optical fiber transmission system for logging information are verified.
