Abstract: At present, in the process of digital building in Sulige Gasfield, there are mainly two kinds of wireless communication technologies applied to single-well wireless monitoring which are data-transmission radio and wireless bridge. Because of bandwidth limitation, the two technologies can’t transmit the data, video and voice at the same time. So, the McWiLL wireless access technology, as a kind of new method, was introduced in this paper. To determine the characteristic, such as effective communication distance, communication effects and so on, the technology was applied for field test in Sulige Gasfield. Results in XX Block proved that the McWiLL broadband wireless technology can establish a data communication network including video surveillance, production data collection, and dispatch voice communication. The technology is feasible in the Sulige Gasfield and it is suggested to conduct further test.
