Example Embodiment

[0024] The turbo-type high-frequency pulse supercharger is composed of a casing 1 , a connecting sleeve 2 , an upper joint 3 , a lower joint 4 , a turbine shaft 5 , a flow restricting sleeve 6 and a flow dividing sleeve 7 . One end of the shell 1 is threadedly mounted with an upper joint 3, the other end of the shell 1 is threadedly mounted with a connecting sleeve 2, and the end of the connecting sleeve 2 is threadedly installed with a lower joint 4; the central hole of the lower joint 4 is provided with a high-pressure flow pipe 13. The high-pressure flow channel pipe 13 communicates with the nozzle on the drill bit through a communication pipe. A turbine shaft 5 is mounted in the casing 1 via a turbine 8 . The turbine 8 is composed of a turbine stator and a turbine rotor. The turbine stator and the turbine rotor are respectively connected and fixed with the casing 1 and the turbine shaft 5 by overfitting. The turbine shaft 5 on one side of the turbine 8 is equipped with an...

Abstract

The invention relates to a turbo-type high-frequency pulse supercharger, which belongs to the technical fields of petroleum, shale gas and geothermal drilling tools. It consists of a housing, a connecting sleeve, an upper joint, a lower joint, a turbine shaft, a restrictor sleeve and a shunt sleeve; one end of the housing is equipped with an upper joint, the other end of the housing is equipped with a connecting sleeve, and the housing is installed through a turbine. Turbine shaft; one end of the turbine shaft is fixed with a cam; a shunt sleeve is installed on the turbine shaft through a restrictor sleeve, a thrust bearing is installed on the turbine shaft on the side of the shunt sleeve, and a supercharging device is installed in the connecting sleeve on the side of the cam. The booster is in sliding connection with the cam. When the supercharger is working, the periodic rotation of the turbine drives the turbine shaft and the cam to rotate, thereby driving the one-way liquid inlet valve through the connecting rod to form a reciprocating motion. Through the reciprocating action of the one-way liquid inlet valve, high-frequency and high-pressure water jets are formed; thus, the high-frequency and high-pressure water jets assist the drill bit in rock breaking, thereby increasing the rock breaking efficiency of the drill bit and reducing drilling costs.

Description

technical field [0001] The invention relates to a turbo-type high-frequency pulse supercharger, which belongs to the technical fields of petroleum, shale gas and geothermal drilling tools. Background technique [0002] In recent years, the global oil market has been sluggish, falling from more than 90 US dollars per barrel to more than 20 US dollars, but the cost of extraction has increased year by year, so effectively increasing the drilling rate is an urgent problem in drilling engineering today. With the depletion of shallow oil and gas resources in my country, oil and gas exploitation will inevitably develop in the direction of deeper and harder formations. Traditional rotary drilling is currently the most widely used drilling method, but when this drilling method encounters hard formations, the drilling efficiency is reduced, the life of the drill bit becomes shorter, the drilling cycle is longer, and the cost is higher. Through the previous literature research, it was...
