井下数据的数字传输

Digital transmission in a borehole

数字传输技术是信息工程和钻井测试技术中的一项关键技术。本文介绍了适用于石油地质领域的数字传输技术,设计了以微处理器为中心的发送、接收等硬件装置,给出了数据接收软件框图,并从理论和实践上对传输线的匹配问题作了较详细的讨论。

Digital transmission is one of the key technology in message engineering and well logging.This paper introduces the technology which is adapted to the digital transmission of petroleum prospecting areas,and also presents the block diagram arid the transmitting and receiving appa- ratus with the microprocessor as center,further it discusses the matching problem of transmitting line in theory arid practice.
