摘要
为实时获得井下动态数据,方便技术人员及时采取各种措施,控制井下生产工具或优化设计方案等,提出了低频电磁波井下通信技术。通过对该技术工作原理和传输信道的理论分析,设计了低频电磁波无线通信设备,并进行了现场试验。试验表明,基于该技术的井下无线通信系统,在下入过程及下入后上传的温度和压力数据稳定,误码率低,数据真实可靠,具有传输可靠、设备成本低、操作简便的特点,有着广阔的应用前景。
Low-frequency electronmagnetic waves downhole communication technique is introduced to acquire real-time downhole dynamic data, help technicians take measures in time, control downhole production means and improve design plan. Low-frequency electronmagnetic waves wireless communication device is designed on the basis of the analysis of its working principle and transmission channel theory and field test is done. The test shows that the downhole wireless communication system based on this technique is characterized by reliable transmission, low cost device and simple operation and has a wide application prospect.
