Electric vehicle-mounted water conservancy drilling equipment

Abstract

The invention relates to the technical field of water conservancy projects, and discloses electric vehicle-mounted water conservancy drilling equipment. The equipment comprises a drill column and a drill bit, the drill bit is rotatably connected to the lower portion of the drill column, the drill column communicates with an inner cavity of the drill bit, well fluid circulates in the drill column and the inner cavity of the drill bit, an inner groove is formed in the inner wall of the drill column, and a torque compensation assembly is clamped in the inner groove. The torque compensation assembly converts energy of the well fluid into rotating energy of the drill column, and a stress plate located below the inner groove and a flow channel located below the torque compensation assembly are arranged on the inner wall of the drill column. According to the equipment, torque acting on a baffle is generated by utilizing different flow rates of the well fluid on the two side faces of the baffle, and the torque is transmitted to the drill column through an upper plate, so that the torque at the lower end of the drill column is increased, the purpose of compensating torque loss of the drillcolumn due to a rotating system is achieved, the rotating speeds of the drill column and the drill bit are increased, and the drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to electric vehicle-mounted water conservancy drilling equipment. Background technique [0002] Drilling is the project of using mechanical equipment to drill the strata into cylindrical holes with a certain depth. Drilling is a systematic project, which is a joint operation of multiple disciplines and types of work using various equipment, tools and materials. At the same time, it is The whole process of construction is quite complicated due to the close connection of multiple programs and the continuous operation of multiple links. Drilling equipment includes circulation system, rotation system and other systems. The rotation system is composed of a turntable, faucet, drill bit and drill string. The rotation system ensures that the drilling equipment provides sufficient rotational torque and power to the drilling tool under the condition of high-pressure circulation of d...
