Below with reference to the accompanying drawings and in conjunction with the embodiments describing the invention in detail.
A kind of throttle type pulse vibration well drilling tool, as shown in figure 1, including hollow housing 1；1 one end of the housing connects
Be connected to pipe nipple 2, the other end be provided with drill bit 3, and housing 1 inside for the impact bar of axial force is provided to drill bit 3
4；The impact bar 4 is arranged on inside housing 1；The inwall of the housing 1 is provided with work of the diameter of bore less than 1 internal diameter of the housing
Make platform 5, between the workbench 5 and the upper pipe nipple 2, form working chamber, hollow throttling valve core 6 is provided with the work intracavity；
The workbench 5 is axially arranged with some discharge orifices 7 along the housing 1；The throttling valve core 6 include with the workbench 5
Valve stem 8 that hole coordinates, and the piston portion 9 that is slidably matched with 1 inwall of the housing；Spring is set with the valve stem 8
10,10 one end of spring props up the piston portion 9, and the other end props up the workbench 5；The valve stem 8 is provided with some throttlings
Hole 11.
Impact bar 4 is all directions type structure, when drilling liquid pressure impulse action is on impact bar 4 so as to produce axial-periodic
Property vibratory shock load, meanwhile, the impact bar 4 of eight cube structures can be revolved in drill bit 3 with the rotation of drilling tool transmission drilling moment of torsion
Axial impact loading can also be produced while turning.
It should be noted that upper pipe nipple 2 is used typically as jointing, its one end is connected on housing 1, the other end
It is connected with drilling equipment, is conventional prior art, as long as realizing linkage function, repeats no more here.Upper pipe nipple direction
One end of throttling valve core can prop up its piston portion, form spacing, prevent throttling valve core from coming off from housing.
In drilling process, when drilling fluid is entered from upper pipe nipple 2, throttling valve core 6 is flowed through, valve element is dual in pressure reduction and spring 10
Under effect, the endoporus along workbench moves reciprocatingly, and while valve element is moved back and forth, stretches in workbench with valve stem 8
The change of hole length, the unlatching quantity of throttle orifice 11 also increase and decrease therewith, it is achieved thereby that mud flow rate size is done periodically becoming
The pulsing jet of change, the runner in pulsing jet Jing impact bars 4 propagate to downwards shaft bottom, and pulsing jet changes bottom-hole flow field,
Improve efficiency of breaking rock.Pressure pulse is acted on impact bar 4 simultaneously so as to is produced axial cyclic vibratory shock load, is made brill
3 also have vibration effect, the vibration effect of drill bit and both waterpower pulses synergy in shaft bottom while rotation, improve
The efficiency of breaking rock of drill bit.
Above-mentioned throttle orifice 11 is arranged on the diverse location of 8 axial direction of the valve stem.Generally, 11 direction of throttle orifice is perpendicular to institute
State the axial direction of valve stem 8.Generally, throttle orifice 11 can arrange 10 or so, be preferably provided with 12, and throttle-flow relaxes, throttling
Effect is good.
Throttle orifice 11 be able to can be more they tended to surely with spaced set, drilling liquid pressure pulse along the axial direction of the valve stem 8
Fixed, frequency of impact is more stable to make impact bar form drill bit, and rock breaking efficiency is more preferable.
Above-mentioned discharge orifice 7 is uniformly arranged 3-5 centered on the axial direction of the housing 1, preferred arrangement 4, it is easy to process,
Symmetrically, piston portion can gradually push down discharge orifice, after losing drilling liquid pressure, throttling valve core be rebounded by spring force,
Continue next action.
In order to ensure the more stable reliability of the throttling valve core course of work, and guarantee restriction effect, 8 outer surface of above-mentioned valve stem
It is slidably matched with the hole wall of 5 endoporus of the workbench.
Above-mentioned valve stem 8 is provided with liquid outlet 12 near one end of the workbench 5, and the diameter of the liquid outlet 12 is less than described
The diameter of 8 endoporus of valve stem, can give full play to the throttling action of throttling valve core, and drilling liquid pressure acts on the throttling valve core
Afterwards, the throttling valve core can be promoted to move to drill bit direction.
The invention simple structure, easy to operate, the advantage of two class technology of integrated pulse drilling well and impact shock drilling well,
Improve the stress of bottom rock, strengthen bottom-hole cleaning, rate of penetration can be effectively improved, dependable performance extensively can be applied
In deep-well and firm hard formation.
The preferred embodiment of the invention is the foregoing is only, it is not to limit the invention, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc. should be included in the invention
Protection domain within.
