Description
Technical field
This utility model relates to drilling field, is specifically related to drilling well bypass valve.
Background technology
In the drilling process carrying out oil, natural gas, shale gas and coal bed gas, be frequently encountered leakage, well overflow, hydrophthalmia
The complex situations such as closure.When there is leakage, owing to bit nozzle size is little, loss circulation material cannot pass through, and need to make a trip replacing
The problems such as BHA carries out plugging operations, thus causes mud loss big, drilling period prolongation.At high density drilling fluid environment
Under, hydrophthalmia easily blocks, and now if carried out kill-job operation, need to make a trip replacing drilling tool, easily causes the situations such as excessive, the well kick of well
Generation.When processing these complex situations, Rapid Circulation passage need to be set up, and when setting up new circulation, generally require frequency
Numerous replacing BHA that makes a trip, it is the longest that this can cause processing complex situations, and brings downhole safety hidden danger.
In order to process down hole problem timely and effectively, using drilling tool by-pass valve the most both at home and abroad, drilling tool bypasses
Valve can set up new circulation canal when leakage.
Seal after pressure reduction that a kind of bypass valve of domestic patent disclosure is produced by the throttling action of spool or pitching, promote
Spool moves downward shear pin, opens by-pass prot, and spool enters in the cavity of bottom.Foreign patent discloses a kind of keyway
The switchable drilling tool by-pass valve of spring.Being mainly characterized by of it: sliding sleeve is connected with keyway, keyway is disposed with two positions,
When alignment pin is positioned at first keyway position, by-pass prot and annular space are closed, when alignment pin is positioned at the second position, by-pass prot with
Annular space is opened, and makes to slide on keyway and replace by the way of increasing hydrodynamic, convenient by the way of arranging spring
It carries out continuous shifting.
The common drawback that above drilling tool by-pass valve exists is: on-off times is less, and consumable accessory is more, close after multiple switching
Envelope easily lost efficacy, and the life-span is shorter.
Utility model content
For above-mentioned deficiency of the prior art, the drilling well bypass valve that this utility model provides solves existing drilling tool bypass
Threshold switch number of times is few, and consumable accessory is more, and the life-span is short, the problem of easy inefficacy.
In order to reach foregoing invention purpose, the technical solution adopted in the utility model is:

Detailed description of the invention
Below detailed description of the invention of the present utility model is described, in order to those skilled in the art understand
This utility model, the common skill it should be apparent that this utility model is not limited to the scope of detailed description of the invention, to the art
From the point of view of art personnel, as long as various change limits and in the spirit and scope of the present utility model that determine in appended claim,
These changes are apparent from, and all utilize innovation and creation that this utility model conceives all at the row of protection.
As Figure 1-Figure 4, this drilling well bypass valve includes valve body 1, spool assembly 2, spring 3, stop 4, receives dress
Put, control device, by-pass port 11 and valve body step 12；Valve body 1 is internally provided with in the middle of the through hole running through upper and lower two ends, valve body 1
Being provided with the by-pass port 11 inside and outside connection, in valve body 1 inside, lower end is provided with valve body step 12；Spool assembly 2 is arranged on valve
In the through hole of body 1, in the middle of spool assembly 2, it is provided through the through hole at upper and lower two ends；Spring 3 one end is fixed on valve body 1, and one
End is fixed on bottom spool assembly 2；Stop 4 is arranged on the upper end of by-pass port 11；Receive device and include cage joint 5 and ball
Basket assembly 6, receives device and is arranged on the lower end of valve body 1, and cage joint 5 is internally provided with the through hole running through its upper and lower two ends；
Cage assembly 6 is fixed on the inside of cage joint 5, and the maximum outside diameter of cage assembly 6 is less than in the minimum of cage joint 5
Footpath, makes to be formed with passage between cage joint 5 and cage assembly 6；Cage assembly 6 upper end is provided with opening, internal in sky
Cavity-like；Controlling device and include composite balls 7 and steel ball 8, the diameter of composite balls 7 is less than the internal diameter of valve body 1, more than spool assembly 2
Internal diameter；The diameter of steel ball 8 is more than the diameter of by-pass port 11, less than the internal diameter of spool assembly 2.
In order to make spool assembly 2 block by-pass port 11 when drilling tool normally works, the height of spool assembly 2 is more than side
Port 11 is to the distance of stop 4.
In an embodiment of the present utility model, in order to make stop 4 simple in construction, use, easy to adjust, stop
4 are set to nut.
In order to ensure that composite balls 7 and steel ball 8 can collect after using, the internal diameter of cage assembly 6 is more than composite balls 7 He
The diameter of steel ball 8.
In specific implementation process, by-pass port 11 can be exposed set up to make composite balls 7 compress spool assembly 2 and quickly follow
Ring passage, the distance of spool assembly 2 lower surface to valve body step 12 more than spool assembly 2 upper surface to by-pass port 11 away from
From.
In order to reduce drilling tool trip-out frequency, improving efficiency of construction, cage assembly 6 inner space is more than or equal to five groups of controls
The volume of device.
Operationally, spool assembly 2 is peaked at stop 4 lower surface by spring 3 to this utility model drilling tool, and blocks bypass
Mouth 11；When by-pass port 11 opened by needs, first putting into composite balls 7 in valve body 1, composite balls 7 arrives and is stuck in spool assembly 2
Upper end, the intrinsic pressure increase of drilling tool, force composite balls 7 and spool assembly 2 to move downward, when spool assembly 2 moves to by-pass port
When 11, form Rapid Circulation passage；When in drilling well, pressure restores balance, it is only necessary to again put into as by-pass port 11 quantity
Steel ball 8, steel ball 8 falls blocking by-pass port 11, causes that valve body 1 is intrinsic pressure to be raised again, and the valve body step 12 of setting stops spool
Assembly 2 declines；Composite balls 7 compressive deformation, reduces volume and by spool assembly 2 and enters in cage assembly 6, the most clear
Reason tamper；Now in valve body 1, circulation recovers, and steel ball 8 also tracks in cage assembly 6, and spool assembly 6 is at spring 3
Effect under move upward, block by-pass port 11, complete a cyclic process.
When drilling well same problem occurs again, only need to repeat above-mentioned pitching operation, just can solve, convenient and swift；Compound
Ball 7 and steel ball 8 can recycle, and this utility model need not frequently pull out of hole, and save the engineering time, and all parts is in use
It is not damaged, increases service life.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this practicality new
Type.Multiple amendment to these embodiments will make it will be apparent that defined herein for those skilled in the art
General Principle can realize in other embodiments in the case of without departing from the spirit or scope of utility model.Therefore, originally
