求翻译：信号的传输是通过生产油井的油管和套管作为传输路径实现“无线传输”的，即不需要传统的数据传输信道—电缆、光纤等。图1为无线传输系统中信号路径示意图。是什么意思？

Signal transmission through the production tubing and casing wells as a transmission path to achieve "wireless", that does not require traditional data transmission channel - cable, optical fiber. Figure 1 is a wireless transmission system in the signal path diagram.

The signal transmission is through the pipeline and pipe production wells as a transmission path for the wireless transmission", that is, do not require traditional data transmission channel - cable, optical fiber, and so on. Figure 1 is a wireless transmission system signal paths in maps.

The signal transmission is through the recovery well drill tubing and the drive pipe took transmission route realization “wireless transmission”, namely does not need traditional the data transmission channel - electric cable, the optical fiber and so on.Figure 1 is in the wireless transmission syst

Signal transmission is through the production of oil well tubing and casing as a transmission path implementation of "wireless transmission", which does not require traditional data transfer channel-cable, optical fiber, and so on. Signal path diagram in Figure 1 is a wireless transmission system.
