Embodiment Construction

[0024] The turbo-type high-frequency pulse supercharger is composed of a housing 1 , a connecting sleeve 2 , an upper joint 3 , a lower joint 4 , a turbine shaft 5 , a restrictor sleeve 6 and a shunt sleeve 7 . One end of the shell 1 is threaded with an upper joint 3, the other end of the shell 1 is threaded with a connecting sleeve 2, and the end of the connecting sleeve 2 is threaded with a lower joint 4; the center hole of the lower joint 4 is provided with a high-pressure flow pipe 13. The high-pressure runner pipe 13 communicates with the nozzle on the drill bit through a communication pipe. A turbine shaft 5 is installed in the housing 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 housing 1 and the turbine shaft 5 through overfitting. The upper centering bearing 9 is installed on the turbine shaft 5 on one side of the turbine 8; the upper cente...

Abstract

The invention relates to a turbo-type high-frequency pulse pressurizer and belongs to the technical field of petroleum, shale gas and terrestrial heat drilling tools. The turbo-type high-frequency pulse pressurizer is composed of a shell, a connecting sleeve, an upper connector, a lower connector, a turbine shaft, a flow limiting sleeve and a flow distributing sleeve. One end of the shell is provided with the upper connector, the other end of the shell is provided with the connecting sleeve, and the turbine shaft is mounted in the shell through a turbine. The head of one end of the turbine shaft is fixedly provided with a cam. The turbine shaft is provided with the flow distributing sleeve through the flow limiting sleeve, the position, on one side of the flow distributing shaft, of the turbine shaft is provided with a thrust bearing, and the position, on one side of the cam, of the connecting sleeve is internally provided with a pressurizing device. The pressurizing device is slidably connected with the cam. When the pressurizer works, through cyclic rotation of the turbine, the turbine shaft and the cam are driven to rotate, so that a one-way liquid inflow valve is driven to move in a reciprocating mode through a connecting rod. Through the reciprocating action of the one-way liquid inflow valve, a high-frequency and high-pressure water jet flow is formed, and thus the purposes that the high-frequency and high-pressure water jet flow assists a drill bit to break rocks is achieved, so that the rock breaking efficiency of the drill bit is improved, and the drilling cost is reduced are achieved.

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...
