摘要
经过 5 0 0 0m长的铠装测井电缆进行高速数字传送是数字化测井仪要解决的关键问题。文章对XDSL的几个技术要点进行了说明 ;阐述了应用宽带接入技术的国产全数字化多级VSP仪器的原理 ;基于该项技术的VSP测井数据传输设备已经完成了室内高温高压试验 ,传输速率达 5 0 0kHz。
High speed digigtal data transmission through long well logging cable is always a key problem in digigtal well logging instruments. This paper introduces XDSL technology, and dscribes the principle of the XDSL based domestic all digitized muti-staged VSP instrument. The HT & HP test of the instrument have been down. The data transmission of the instrument is 500 kHz.
