Description
Technical field
The present invention relates to a kind of down-hole equipment in field of oil development more particularly to a kind of rotating flow distribution formula axial impacts
Drilling tool.
Background technology
The raising of hardpan rate of penetration is always an insoluble problem in drilling engineering.Unit volume
The broken energy needed of hardpan is larger.Conventional drilling technologies are rotary drilling technology at present, and drill bit is driven by drilling rod
It rotates to realize the broken of rock, realizes that pressure (bit pressure) of the drill bit to rock, the pressure to bore by the dead weight of drilling rod
The inside of head wedging rock, but this kind of pressure is static pressure, it is relatively low to the crushing efficiency of the rock of hardpan.
Experiment proves that percussion drilling technology is a kind of method effectively improving hardpan rate of penetration.The technical backstopping in
Rotary percussion drilling tool, the tool are mounted on the upper end of drill bit, and it can be axial impact loading to convert surging for a part, are formed
Unidirectional axial impact realizes impact grinding of the drill bit to rock, forms volumetric fracture.The technology has been applied at present,
Corresponding rotary percussion drilling tool is also had developed respectively both at home and abroad, according to the difference of the mode of its realization, is broadly divided into jet stream

The structure for hitting in drilling tool the direction of motion for changing impact part includes mainly：1) fluidic cavities；2) valve body；3) cavity is vibrated.It penetrates
The direction of motion that cavity mainly changes jet stream by the variation of inside cavity pressure is flowed, when jet stream occurs, due to the height of drilling fluid
Speed movement, and have many solid phase particles in drilling fluid, more serious to the erosion of fluidic channel when using this kind of mode, shadow
Ring the service life of tool.And valve type churn drilling tools mainly realizes impact by the axially reciprocating of the structure of valve body
The commutation of component movement, valve body is in axially reciprocating, when it moves to extreme position, can generate impact to position-limit mechanism
Effect, this kind of percussion can the serious service life for reducing valve body.Valve body is by prominent when changing fluid direction of motion
So change nyctitropic mode, the mode of this mutation can influence stability when valve body work, be unfavorable for the stability of tool.
And when using oscillation cavity, the characteristics of due to its structure, cause its generated ballistic work smaller, it is broken that hardpan cannot be met
The needs of rock.
The characteristics of according to existing rotary percussion drilling tool, is engaged in the practice and warp of the sector in conjunction with the present inventor for many years
It tests, it is proposed that a kind of rotating flow distribution formula axial impact drilling tool, the shortcomings that overcome the prior art.

In the process of running, wherein tubular block stamp 5 and turbine turn rotating flow distribution formula axial impact drilling tool 100 of the present invention
There are four types of states for 6 tool of cylinder；(the rotation of turbine rotating cylinder 6 is described so that turbine rotating cylinder 6 is rotated clockwise and (seen from bottom to top) as an example
Direction is by depending on rotation direction that wherein turbo blade 65 is arranged).
As shown in Figure 11 A, Figure 11 B, in the first state, turbine rotating cylinder 6 rotates clockwise, and upper open-work 21 is by the first fan
Shape flange frame cylinder 612 blocks, meanwhile, lower open-work 22 is blocked by the second fan-shaped flange frame cylinder 622, and high-pressure fluid cannot
Into upper cavity 91 and lower chamber 92, at this point, tubular block stamp 5 does not move.
As shown in Figure 12 A, Figure 12 B, in second of state, turbine rotating cylinder 6 continues to rotate clockwise, upper open-work 21 and
Gap 93 is connected to so that the low-pressure fluid in upper cavity 91 can be discharged by gap 93, multiple through-holes 415；Meanwhile lower open-work 22 with
Second fan-shaped open-work 621 is connected to so that high-pressure fluid can flow into lower chamber 92, and the lower chamber 92 of tubular block stamp 5 enters at this time
Low-pressure fluid is discharged in high-pressure fluid and upper cavity 91, and tubular block stamp 5 is pushed to move downward.
As shown in Figure 13 A, Figure 13 B, in the third state, turbine rotating cylinder 6 continues to rotate clockwise, and upper open-work 21 is again
It is 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 cannot enter upper cavity 91 and lower chamber 92, at this point, tubular block stamp 5 does not move.
As shown in Figure 14 A, Figure 14 B, in the 4th kind of state, turbine rotating cylinder 6 continues to rotate clockwise, upper open-work 21 and
One fan-shaped open-work 611 is connected to so that and high-pressure fluid can flow into upper cavity 91, meanwhile, lower open-work 22 is connected to gap 93 so that
Low-pressure fluid in lower chamber 92 can be discharged by gap 93, multiple through-holes 415；The upper cavity 91 of tubular block stamp 5 enters at this time
Low-pressure fluid is discharged in high-pressure fluid and lower chamber 92, and tubular block stamp 5 is pushed to move upwards.
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 movement of a cycle, in being moved through for a cycle
Cheng Zhong, tubular block stamp 5 provide primary axially downwardly shock loading to drill bit；In this way, under the driving of high-pressure fluid, tubular punching
Hammer is constantly back and forth moved up and down implements axial impact to drill bit.
From the above mentioned, rotating flow distribution formula axial impact drilling tool proposed by the present invention, can pass through the axial direction of tubular block stamp
It moves back and forth to realize the axial impact to drill bit, increases the depth of drill bit wedging rock interior, while to bit cutting tooth rim
The rock on side generates destruction, generates more micro-cracks so that the anti-shear ability of rock reduces, to improve the broken of rock
Efficiency improves rate of penetration, reduces drilling period, reduces drilling cost.In the rotating flow distribution formula axial impact drilling tool, cylinder
The commutation of shape block stamp is realized by the continuous rotation of turbine rotating cylinder, and turbine rotating cylinder continuous rotation is not in the mutation of rotating speed
And the vibration generated by mutation, thus, it is possible to improve the stability of turbine rotating cylinder and its service life, and the rotating flow distribution formula axis
Commutation to percussion drilling tool is relatively simple, and the frequency of tool can be according to the quantity and shape for changing turbo blade come real
Now adjust.
The foregoing is merely the schematical specific implementation modes of the present invention, are not limited to the scope of the present invention.It is any
Those skilled in the art, made equivalent variations and modification under the premise of not departing from design and the principle of the present invention,
The scope of protection of the invention should be belonged to.
