The invention discloses a cone drill bit for oil exploration and production. The cone drill bit comprises a joint, a tooth palm, a cone and cutter wings, wherein the tooth palm is fixedly connected with the joint and is arranged on the lower side of the joint in a biased manner, the cone is in clearance fit with the tooth palm, and the cutter wings are located on the two sides of the tooth palm and are movably connected with the joint; and the cone comprises a main cone and a back cone, the back cone is in clearance fit with the tooth palm and is integrally formed with the main cone, a plurality of conical teeth surrounding the main cone are arranged on the main cone, and the conical teeth are inlaid on the outer side of the main cone. On the basis of the prior art, by improving the structure of the cone drill bit, the single cone is used, the cutter wings are additionally arranged, and the cone and the cutter wings cooperate with each other so as to effectively improve the crushing efficiency of the cone bit on the stratum, that is, the cone adopts a stepped structure, the crushing effect on the stratum is improved, the cone is large in size, the tooth distribution area is increased, the cone strength is improved, the cutter wings also improves the small-displacement scraping effect on the stratum, and the mechanical drilling speed of the cone drill bit for the different stratum is improved under mutual cooperation.
