摘要
针对测井信号长距离传输过程中,信号因干扰失真或变形、信号传输速率不高的问题,引入扩频通信技术,提出设计一种基于扩频通信技术的测井信号长距离传输系统。讨论了扩频通信技术解决测井信号传输问题的技术方案,介绍了系统的总体架构及各功能模块的设计,并以匹配滤波模块为例探讨了系统的开发与实现。仿真实验及模拟测试初步验证了利用扩频通信技术改进测井信号长距离传输系统的可行性,为进一步提高该类系统的抗干扰性能及传输速率提供了新的思路和方法。
In this paper the topic is trying to introduce a new way to improve the signal distortion caused by electro- magnetic interference and formation pressure during logging signal transmission. In this topic, logging signal transmission system was divided into sub-function modules and designed based on direct spread spectrum（DSS）theory. Using DSS theory in logging signal transmission system can improve the logging signal anti-jamming performance and the preliminary test had proved this way possible and effective.
