This invention discloses an intelligent oil production system for electric pump wells, a tubing string, and a method of use, relating to the field of downhole communication technology. The system includes a surface control cabinet, an AC carrier cable, a wireless transceiver connector (upper and lower), a DC carrier cable, and downhole intelligent equipment. The surface control cabinet supplies power to the downhole intelligent equipment via the AC carrier cable, the wireless transceiver connector (upper and lower), and the DC carrier cable. The surface control cabinet performs bidirectional AC carrier communication with the wireless transceiver connector (upper and lower) via the AC carrier cable. The wireless transceiver connector performs bidirectional DC carrier communication with the downhole intelligent equipment via the DC carrier cable. This invention reduces the number of cables, solving the problem of the difficulty of laying multiple cables on the external tubing string during construction, while also reducing tubing string costs and production costs.
