| description | The invention discloses an anti-blocking rotary well wall coring drill bit. Comprising a drill bit base body which is of a cylindrical barrel-shaped structure. A plurality of cutting blocks are evenly distributed on the front portion of the drill bit base body in the circumferential direction, and a plurality of cutting drills are evenly distributed on the outer end faces of the cutting blocks. A plurality of wear-resistant belts are uniformly distributed at the rear part of the drill bit base body along the circumference; and a plurality of anti-clamping and anti-grinding nails are uniformly distributed on the wear-resistant belt. The anti-sticking drill bit has the beneficial effects that the multiple anti-sticking grinding nails are arranged on the rear portion of the drill bit base body, and the situation that the drill bit is stuck can be prevented.
