| 中文摘要: |
| 井下声波通信技术利用周期性管柱信道实时传输声波数据，相比于其他通信方式，具有适应性好、复杂度低、传输效率高等优点，在随钻地质导向、油水井监测等方面有广阔的应用前景，是发展智能油田的关键技术之一。本文主要综述上世纪90年代以来关于信道物理模型、信道容量、声信号调制与接收方法等关键问题的研究历程，并对通信系统的设计要点与国内外相关产品的现场应用进行梳理，为后续的技术改进提供依据。 |
| 英文摘要: |
| Downhole acoustic communication technology, which transmits acoustic data based on periodic string channel in real time, has the advantages of good adaptability, low complexity and high transmission efficiency compared with other communication methods. As one of the key technologies in intelligent oilfield, it has a broad application prospect in geosteering and oil-well monitoring. This paper mainly reviews the research on channel physical model, capacity, signal modulation and reception methods since 1990s, and summarizes the design points of the system and its field application, this will guide the later development. |
