Abstract
A logging-while-drilling optical fiber communication device includes a rotary wireless transceiver module fixed on a protective connector; an active antenna of the rotary transceiver is placed in the first drill pipe by drilling hole through the protective connector; an optical fiber communication drawworks is located at the top of a second drill pipe, the optical fiber is downwardly released into other under-well drill pipes, the bottom of the optical fiber is connected with the well-bottom wireless receiving module; the lowest part of the drill pipe are provided with a drilling data acquisition device and a well-bottom wireless transmitting module. In the present invention, the optical fiber cable is used as transmission medium, by the means of modulating information data obtained by well logging into optical wave, and transmitting to the optical communication link, high-speed bi-directional transmission of well logging information can be realized.
