A kind of nearly drill bit three-dimensional bumper jar of the present invention is made of simple metal element, and high temperature resistant and wear resistance are strong, work
Make long lifespan, well track is made to have obtained oriented control, and extend the service life of tool, reduce the number that makes a trip, saves
About drilling cost.
When in use, the second connector 3.10 is connect a kind of nearly drill bit three-dimensional bumper jar of the present invention with drilling rod, the first connector
1.11 connect with drill string and drill bit.When work, inner cavity of the drilling fluid through the second connector 3.10, connecting shaft 3.3 inner cavity enter shake
It hits inside device, fluid channel, the inner cavity of the first sleeve 1.3 then through turbocharging assembly, ring cavity 1.6.4, second sleeve 1.7
Inner cavity, the first waist-shaped hole 1.8.4, the second waist-shaped hole 1.9.3 flow out bumper jar.The high pressure well liquid flowed into inside drilling rod drives whirlpool
Rotor rotation is taken turns, the concentric rotational movement around turbine central axis is formed, to convert the kinetic energy of cleaner for high-pressure drilling fluid to high speed
The mechanical energy of rotation, and pressure balancing system is transmitted to by pressure side or valve disc 1.8 by turbine spindle 1.2.1.Due to valve disc 1.8
It is two effect partials of the same part by pressure side with pressure balancing system, so turbine spindle 1.2.1 will drive valve disc 1.8
High speed rotation together.Since valve seat 1.9 is fixed, in 1.8 high speed rotation of valve disc, the first waist-shaped hole 1.8.4 and valve of valve disc 1.8
The second waist-shaped hole 1.9.3 on seat 1.9 is overlapping, and makes drilling fluid in the rotation formed by valve disc 1.8 and valve seat 1.9
The circulation area generating period of valve changes, and to make the flow stream pressure generating period of 1.8 upstream of valve disc change, that is, produces
Pressure pulse.
When the area of passage change between valve disc 1.8 and valve seat 1.9 is small, the upstream pressure of rotary valve increases.Work as flow-passing surface
When product is minimum, i.e., as the first waist-shaped hole 1.8.4 of valve disc 1.8 and the second waist-shaped hole 1.9.3 on valve seat 1.9 not be overlapped,
The upstream high flow stream pressure of rotary valve reaches maximum.Great flow stream pressure acts on piston 3.6 and connecting shaft 3.3,
Make disc spring group 3.8 compress and the high pressure kinetic energy of drilling fluid is changed into disc spring potential energy to store.The compression movement of disc spring group 3.8
The shell of bumper jar through the invention transmits motion to drill bit, and bottomhole is made to move downward.
When the area of passage between valve disc 1.8 and valve seat 1.9 becomes larger, the pressure reduction of the transition joint side of rotary valve.
When area of passage maximum, i.e., when the first waist-shaped hole 1.8.4 of valve disc 1.8 and the second waist-shaped hole 1.9.3 on valve seat 1.9 are complete
When overlapping, the upstream high flow stream pressure of rotary valve reaches minimum.Since bit pressure is more than flow stream pressure minimum, so preceding place
It releases energy in the disc spring group 3.8 of compressive state, disc spring group 3.8 extends and transmits motion to brill by the shell of bumper jar
Head makes drill bit move upwards.
Since turbine can provide stable rotary motion under cleaner for high-pressure drilling fluid effect so that rotary valve has certain week
Phase, under periodic pressure impulse action, a kind of nearly drill bit three-dimensional bumper jar of the invention produces periodically height in an axial direction
Frequency wriggle, so that the friction condition between drill string and the borehole wall is changed, drill string elasticity send brill the instantaneous coefficient of sliding friction increasing
Long speed reduces, to reduce frictional resistance, improve rate of penetration.Meanwhile by the way that cleaner for high-pressure drilling fluid is introduced in pressure balancing system
Chamber, flow stream pressure act on pressure balance by the bottom end face of pressure side or the valve disc dome platform 1.8.2 of valve disc 1.8, bore simultaneously
Well liquid enters in the second cavity 1.12, forms low pressure liquid.The interaction of highly pressurised liquid and low pressure liquid forms pressure difference, reduces
The load of bearing, to extending the working life of bearing.And used in the service life of bottomhole depends primarily on
The operating time of bearing, thus pressure balancing system extends the service life of the bumper jar of the present invention.
Wherein, a kind of nearly drill bit three-dimensional bumper jar of the invention, is typically mounted near drill bit, in actual use in high pressure
Itself generates axial high frequency and wriggles under the driving effect of drilling fluid, and since the invention has used a kind of the asymmetric of Concentric rotation
Formula valve arrangement generates the radial vibration of high frequency while itself axial high frequency can be made to wriggle.Its axial high frequency wriggle by drill string with
Static friction state between the borehole wall changes into sliding friction state.Meanwhile radial dither cycle reduces drill string
Normal pressure between the borehole wall.The common influence of both effects makes the growth of the frictional resistance between bottom hole assemblies and the borehole wall
Speed significantly reduces, and can significantly reduce frictional resistance, prevent to drag pressure phenomenon, improves the effect of load transfer, improves machine
Tool drilling speed saves drilling cost.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
