Informationized drilling system and method suitable for in-advance prediction of unfavorable geological structure plane

The invention discloses an informationized drilling system and an informationized drilling method suitable for in-advance prediction of an unfavorable geological structure plane and aims to overcome the shortcoming that a weak layer is identified only by coring identification in a weak interlayer drilling technique in the prior art so as to discover the spatial distribution position of an unfavorable geological body or geological structure plane in time in a drilling process. The system comprises a computer, a drilling rig, a geological radar, a drill pipe and a drill bit; the drill pipe is connected with the drill rig; the drill bit is arranged at the tail end of the drill pipe; the inside of the drill pipe is of a hollow structure; the geological radar is arranged inside the drill pipe and is movably connected with the drill pipe; and the computer is electrically connected with the geological radar. The method comprises the following main steps of: erecting the drill rig at the system; making an electric wi
