The invention provides a transposition
drill bit for oil and gas exploitation, and relates to the technical field of oil and gas exploitation. The transposition
drill bit for oil and gas exploitation comprises an
alloy base body, a fixed fluted disc is arranged on the upper portion of the
alloy base body, a cutter wing is arranged in the middle of the fixed fluted disc, a plurality of
cutting teeth are fixedly connected to the
peripheral wall of the cutter wing, a rotating shaft is fixedly connected to the middle of the cutter wing, and the rotating shaft is rotationally connected with the fixed fluted disc. The blades are provided with limiting mechanisms connected with the fixed fluted disc. The fixed fluted disc is rotationally connected with the cutter wings through the rotating shafts, and the limiting mechanisms are arranged between the fixed fluted disc and the cutter wings, so that after the
cutting teeth are abraded, the intact
cutting teeth and the abraded cutting teeth can be subjected to transposition through transposition of the cutter wings, the effect of recycling the
drill bit is achieved, the loss of the
drill bit is reduced, the frequency of replacing the
drill bit is reduced, and the service life of the
drill bit is prolonged. And the use cost of the drill bit is further reduced.
