Background technology
The prior art drilling fluid conveying device comprises drilling fluid pump, drilling rod and drill bit.Drilling fluid pump is transported to downhole drill bit with the drilling fluid supercharging by drilling rod, the high-pressure delivery that drilling fluid needs drilling fluid pump to produce.The weak point of prior art is, the drilling fluid pump that produces high pressure can cause rapid wearing because of power output is excessive, and the possibility of stopping boring of having an accident is big, and Fuel Consumption is big.
Summary of the invention
Technical problem to be solved provides a kind of drilling fluid conveying device that can use the smaller power drilling fluid pump and the self-oscillation booster is housed.
Solve the technical scheme of its technical problem, comprise drilling fluid pump, diesel engine, more piece drilling rod, tool joint, drill bit and self-oscillation booster; Drilling fluid pump and diesel engine are contained in aboveground, and the output shaft of diesel engine is connected with the power shaft of drilling fluid pump; Adorn first section tool joint between the upper end of first section drilling rod and the liquid outlet of drilling fluid pump, the lower end of latter end drilling rod is connected with the upper end of drill bit; The self-oscillation booster comprises housing, inlet opening, throttling pressurized hole, diffusion hole, cylindrical cavity and weep hole; Be followed successively by inlet opening, throttling pressurized hole, diffusion hole, cylindrical cavity and weep hole in the endoporus of housing from top to bottom; The inlet opening is up big and down small turbination hole, and there are several vertical guiding gutters on the surface of inlet opening; The inlet opening is following to be the throttling pressurized hole, the throttling pressurized hole is following to be up-small and down-big diffusion hole, diffusion hole is following to be cylindrical cavity, and the diameter of cylindrical cavity equals the following diameter of diffusion hole, and the spirality guiding gutter that can further increase self-excited pulse pressure is arranged on the surface of cylindrical cavity;
The self-oscillation booster can be contained in the endoporus of first section tool joint, also can be contained between the upper end of the lower end of latter end drilling rod and drill bit, in the middle of also can being contained in the endoporus of one section drilling rod.
Drilling liquid flow enters cylindrical cavity, produces self-excited pulse, has increased the pressure of liquid, and the spirality guiding gutter can further increase the pressure of self-excited pulse.
Beneficial effect: the present invention is applied to the conveying of drilling fluid in the drillng operation.Beneficial effect is, because the self-oscillation effect can enlarge markedly the pressure of drilling fluid, even reduce the output pressure of drilling fluid pump, perhaps uses lower-powered drilling fluid pump, also can reach the pressure that more powerful drilling fluid pump produces; Thereby can reduce the consumption of fuel and improve the rate of penetration of drilling well, can save diesel-fuel consumption more than 4 tons, improve penetration rate 30%-120%, prolong the application life of drilling fluid pump.
