随着测井新理论和新方法的不断出现，传统的测井通信技术已成为制约测井技术发展的瓶颈。如何在有限的带宽范围内获取更大的数据传输速率和传输距离已成为测井通信研究的重点。以石油测井井下环境为背景设计出一套基于电力线 OFDMA（Orthogonal Frequency Division Multiple Access）载波技术的单芯电缆测井通信系统。系统采用基于OFDMA技术的电力线载波通信芯片SM2200完成井下仪器与地面仪器间的宽带数据传输，使得测井通信变得更加高效、可靠、经济。

With the occurrence of new theories and methods, the traditional well-logging communication technology becomes the bottleneck of its development. How to obtain faster transmission rate and further transmission distance in limited bandwidth is now focus of well-logging communication. This paper proposes a communication system with single-core logging cable and based on OFDMA(Orthogonal Frequency Division Multiple Access) and power line carrier technology. The system uses OFDMA-based power line carrier chip SM2200 to implement the broadband data transmission between surface instrument and subsurface equipment, thus enabling the well-logging communication to become more efficient, reliable and economic.
