Description
Technical field
The present invention is about down-hole equipment a kind of in field of oil development, particularly relates to a kind of rotating flow distribution formula axial impact
Drilling tool.
Background technology
An insoluble problem in the raising of hardpan rate of penetration always drilling engineering.Unit volume
The energy that hardpan crushes needs is bigger.Conventional drilling technologies is rotary drilling technology at present, drives drill bit by drilling rod
Rotating and realize the broken of rock, realize the drill bit pressure (the pressure of the drill) to rock by the deadweight of drilling rod, this pressure makes to bore
The inside of head wedging rock, but this kind of pressure is static pressure, and it is relatively low to the crushing efficiency of the rock of hardpan.
Test proves that percussion drilling technology is a kind of method being effectively improved hardpan rate of penetration.This technical backstopping in
Rotary percussion drill by driving well tool, this instrument is arranged on the upper end of drill bit, and changing surging of a part can be formed into axial impact loading
Unidirectional axial impact, it is achieved the drill bit impact grinding to rock, forms volumetric fracture.This technology has been applied at present,
Have developed corresponding rotary percussion drill by driving well tool the most respectively both at home and abroad, according to the difference of its mode realized, be broadly divided into jet
Formula spin drilling tool, valve type spin drilling tool, self-excited oscillation type spin drilling tool etc..Although this technology obtains certain application, but

The structure of the direction of motion changing impact part in hitting drilling tool specifically includes that 1) fluidic cavities；2) valve body；3) vibration cavity.Penetrate
Stream cavity is mainly by the direction of motion of the change change jet of inside cavity pressure, when there is jet, due to the height of drilling fluid
Speed motion, and drilling fluid has a lot of solid phase particles, when using this kind of mode, the erosion to fluidic channel is more serious, shadow
Ring the service life of instrument.And valve type churn drilling tools mainly realizes impact by the axially reciprocating of the structure of valve body
The commutation of parts motion, valve body is when axially reciprocating, when it moves to extreme position, position-limit mechanism can be produced impact
Effect, the service life of the reduction valve body that this kind of percussion can serious.Valve body, when changing the fluid direction of motion, is by prominent
So change nyctitropic mode, the mode of this sudden change, stability during valve body work can be affected, be unfavorable for the stability of instrument.
And when using vibration cavity, due to its structure, cause ballistic work produced by it less, it is impossible to meet hardpan and break
The needs of rock.

Being blocked by the first fan-shaped flange frame cylinder 612, meanwhile, lower open-work 22 is blocked by the second fan-shaped flange frame cylinder 622 again,
High-pressure fluid can not enter upper cavity 91 and lower chamber 92, and now, tubular block stamp 5 does not moves.
As shown in Figure 14 A, Figure 14 B, when the 4th kind of state, turbine rotating cylinder 6 continues to rotate clockwise, upper open-work 21 and
One fan-shaped open-work 611 connects so that high-pressure spray physical ability flows in upper cavity 91, and meanwhile, lower open-work 22 connects with gap 93 so that
Lowpressure stream physical ability in lower chamber 92 is discharged by gap 93, multiple through hole 415；Now the upper cavity 91 of tubular block stamp 5 enters
High-pressure fluid and lower chamber 92 discharge low-pressure fluid, promote tubular block stamp 5 to move upward.
Turbine rotating cylinder 6 continues to rotate clockwise, and tubular block stamp 5 and turbine rotating cylinder 6 are returned to the position of the first state；This
Sample, rotating flow distribution formula axial impact drilling tool 100 of the present invention completes the motion in a cycle, being moved through of a cycle
Cheng Zhong, tubular block stamp 5 provides the most axially downwardly shock loading to drill bit；So, under the driving of high-pressure fluid, tubular rushes
Hammer constantly back and forth moves up and down implements axial impact to drill bit.
From the above mentioned, the rotating flow distribution formula axial impact drilling tool that the present invention proposes, can pass through the axial of tubular block stamp
Move back and forth and realize the axial impact to drill bit, increase the degree of depth of drill bit wedging rock interior, simultaneously to bit cutting tooth rim
The rock on limit produces and destroys, and produces more micro-crack so that the anti-shear ability of rock reduces, thus improves the broken of rock
Efficiency, improves rate of penetration, reduces drilling period, reduces drilling cost.In this rotating flow distribution formula axial impact drilling tool, cylinder
The commutation of shape block stamp is to be realized by rotating continuously of turbine rotating cylinder, and turbine rotating cylinder rotates the sudden change not havinging rotating speed continuously
And the vibration produced by sudden change, thus can improve stability and the service life thereof of turbine rotating cylinder, and this rotating flow distribution formula axle
Relatively simple to the commutation of percussion drilling tool, the frequency of instrument can be come real according to the quantity and shape that change turbo blade
Now regulate.
The foregoing is only the schematic detailed description of the invention of the present invention, be not limited to the scope of the present invention.Any
Those skilled in the art, equivalent variations done on the premise of without departing from the design of the present invention and principle and amendment, all
The scope of protection of the invention should be belonged to.
