The invention discloses a drilling fluid conveying device provided with self-oscillation superchargers, and belongs to the technical field of drilling fluid conveying devices. The technical problem to be solved is to provide a drilling fluid conveying device which uses a low-power drilling fluid pump and is provided with self-oscillation superchargers. To solve the technical problem, the invention adopts the technical scheme that the drilling fluid conveying device comprises a drilling fluid pump, a drill rod, a drill rod joint, a drill bit and the self-oscillation superchargers; the drill rod joint of the first section is connected between the upper end of the drill rod of the first section and a fluid outlet of the drilling fluid pump; one self-oscillation supercharger is arranged in an inner hole of the drill rod joint of the first section, and the other self-oscillation supercharger is arranged between the lower end of the drill rod of the last section and the upper end of the drill bit; the self-oscillation supercharger comprises a shell, a water inlet hole, a throttling supercharging hole, a diffusion hole, a columnar inner cavity and a water outlet hole; the surface of the water inlet hole is provided with a longitudinal guide groove; and the surface of the columnar inner cavity is provided with a spiral guide groove. The drilling fluid conveying device is applied to conveying drilling fluid. The drilling fluid conveying device has the advantages that the device can remarkably increase the output pressure of the drilling fluid, uses the low-power drilling fluid pump to achieve the pressure output by a high-power drilling fluid pump, reduces the consumption of fuels, and improves the drilling speed.
Description
technical field [0001] The invention belongs to the technical field of drilling fluid delivery devices. Background technique [0002] The drilling fluid conveying device in the prior art includes a drilling fluid pump, a drill pipe and a drill bit. The drilling fluid pump pressurizes the drilling fluid and transports it to the downhole drill bit through the drill pipe. The drilling fluid needs high-pressure delivery generated by the drilling fluid pump. The disadvantage of the prior art is that the high-pressure drilling fluid pump will wear out rapidly due to excessive output power, and the possibility of accident stop drilling is high and the fuel consumption is large. Contents of the invention [0003] The technical problem to be solved is to provide a drilling fluid conveying device which can use a drilling fluid pump with a smaller power and is equipped with a self-excited oscillation supercharger. [0004] The technical solution to solve its technical problems, inc...
