Permanent sensor will realize the function of data acquisition, process and transmission, realize monitoring oil-gas reservoir real-time dynamically under network condition with Internet technology. Introduced is the latest advance of network sensor technology based on TCP/IP protocol. We point out that the FBG （Fiber Bragg Grating） temperature and pressure sensor can be used as the permanent sensor, and we also offer a system design scheme based on the wireless IP sensor network. The data acquisition and transform model which suits for permanent real-time monitoring reservoir dynamically under network has also been founded. We need work over the field that it includes the method of probe design, fixing technics, distributed measuring network, the method network distribution of monitoring oil-gas reservoir and realization approach, the method of data process for monitoring reservoir real-time and visible display for 3-D space and 4-D time of reservoir.
