Abstract

The invention discloses a new type of drilling rig for oil exploration, which comprises a main drilling shaft, a sliding main body, a dragon body and a main drill bit. The end of the main drilling shaft is connected with the sliding main body, and the bottom of the sliding main body is An intermediate connecting shaft is installed at the end of the intermediate connecting shaft, and the end of the intermediate connecting shaft is provided with an auger shaft. The bottom end of the auger shaft is equipped with the main drill bit. A drill shaft sleeve is installed on the end face of the main drill shaft, explosive tubes are installed at both ends of the sliding main body, a lubricating sleeve is installed in the middle hole groove, a drainage channel is arranged inside the sliding main body, and the auger shaft The end face is equipped with the dragon body through the dragon connecting bearing bush. The beneficial effect is that: the use of the Jiaolong body and the main drill bit to detect oil in the rock has higher detection efficiency, and the cooperation of the explosive tube makes the rock crushing more thorough.

Description

technical field [0001] The invention belongs to the technical field of petroleum detection equipment, and in particular relates to a novel drilling rig used for petroleum exploration. Background technique [0002] Drilling rigs for oil exploration are key machines for oil exploration and geological mine drilling. The drill bit is a tool for breaking the formation and forming a wellhead. The quality of its various parameters is directly related to the efficiency of the drilling rig and the overall performance of the drilling rig. At present, there are no similar disposable drill bits, joints and drill pipes in oil exploration construction. The existing drill bits can not meet the requirements of lowering the explosives for exploration from the middle of the drill pipe after drilling in the area where the well wall cannot be formed. The reduced adaptability can no longer meet the needs of current petroleum and related geological exploration. Contents of the invention [000...
