Abstract
The utility model discloses a kind of large scale fishing junk cup, it is characterized in that the hydrophthalmia portion of cup bar has oblique nozzle under cup, cup there are fan-shaped rim of a cup and cup hoof mouth, before salvaging junk, this instrument and the drilling tool entering well are connected, under get into shaft bottom before progressively transfer drilling tool, sand setting at the bottom of flushing manhole, check and approve salvaging side after shaft bottom transferred to by instrument to enter, open systemic circulation discharge capacity and intermittent rotary rotating disk, now the mud of huge discharge is through hydrophthalmia, oblique nozzle plays junk from shaft bottom to preshoot is upwards dug from fan-shaped rim of a cup, when junk is by the unexpected increase because of annular space area during fan-shaped rim of a cup, flow velocity reduces and starts again to fall, namely the junk fallen and cup just enter in cup timing, maybe stir junk when the junk fallen meets with the cup hoof mouth rotated with turntable intermittent to move toward cup center, in addition the support of the borehole wall is had, junk just enters smoothly in cup to be formed and salvages.
Description
Technical field
The utility model relates to be salvaged in the large scale junk not easily salvaged in shaft bottom in petroleum drilling well workover.
Background technology
When falling the first-class large scale junk of iron chains in multiple gear wheel, the wing of PDC drill bit, rig tool in petroleum drilling well workover construction, the instruments such as many wheels fisher and reacting cycle fishing cup can not salvage junk, can only take to process bottom hole falling article by the method for efficient milling shoes milling, but again because the tooth etc. of carbide alloy, PDC drill bit wing upper mounting clamp on gear wheel has the reasons such as certain abrasion resistance during milling, efficient milling shoes not necessarily can thorough milling these large junks clean, continue namely to delay timeliness with efficient milling shoes milling again, again retarding oil gas exploration progress.
Summary of the invention
The drawback existed in accident settlement for the large junk instrument of the on-the-spot current various salvaging used of drilling and repairing well and hidden danger, the purpose of this utility model has aimed to provide a kind of large scale fishing junk cup, this fishing cup adopts in concentric circles and digs out a fan-shaped space, salvages the object of junk to increase principle annular space returning area to realize large scale junk by fan-shaped space being returned realization to fishing cup.
The purpose of this utility model completes like this:
A kind of large scale fishing junk cup, composition is leaked primarily of oblique nozzle, hydrophthalmia, long support muscle, short brace rod, cup, fan-shaped rim of a cup, cup hoof mouth, cup bar, joint and cup, oblique nozzle opens the bottom at cup bar and hydrophthalmia, long support muscle and short brace rod are supported on the end of cup and the front and back surrounding of cup bar, fan-shaped rim of a cup is the one block of plate being welded on cup front portion, cup hoof mouth is out a horse-hof shape slope gear mouth on cup, it is evenly open the hole in bottom of cup that cup leaks, and the top of cup bar is processed with joint.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model can be processed according to the size scene of junk in well and borehole size, with low cost, has the advantage generally used.
2, the utility model easily drags for and obtains other fishing tool and can not drag for and obtain and the efficient milling shoes large scale that not easily milling is clean, irregular junk, improves fishing success ratio and timeliness.
Accompanying drawing explanation
Fig. 1 is the utility model positive view.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, a kind of large scale fishing junk cup, primarily of oblique nozzle 1, hydrophthalmia 1a, long support muscle 2, short brace rod 3, cup 4, fan-shaped rim of a cup 4a, cup hoof mouth 4b, cup bar 5, joint 6 and cup leak 7 compositions, oblique nozzle 1 opens the bottom at cup bar 5 and hydrophthalmia 1a, long support muscle 2 and short brace rod 3 are supported on the end of cup 4 and the front and back surrounding of cup bar 5, fan-shaped rim of a cup 4a is the one block of plate being welded on cup 4 front portion, cup hoof mouth 4b is out a horse-hof shape slope gear mouth on cup 4, it is evenly open the hole bottom cup 4 that cup leaks 7, the top of cup bar 5 is processed with joint 6.
When there is the first-class large-scale junk of gear wheel, iron chains in shaft bottom, fail to drag for through instruments such as blue, the many wheel fishers of reacting cycle salvaging and obtain, or bottom hole falling article is connected the joint 6 of this instrument when also thoroughly process is unclean with the drilling tool entering well after efficient milling shoes milling, under be drilled into apart from 0.5 meter, shaft bottom or in advance sand setting is hampered time and turn on pump circulation slowly rotate rotating disk, progressively transfer this instrument, the sand setting at the bottom of flushing manhole.Check and approve salvaging side to enter, instrument leaves systemic circulation discharge capacity after transferring to shaft bottom and intermittent rotary rotating disk, now the mud of huge discharge is through hydrophthalmia 1a, oblique nozzle 1 plays junk from shaft bottom to preshoot is upwards dug from fan-shaped rim of a cup 4a, when junk is by the unexpected increase because of annular space area during fan-shaped rim of a cup 4a, flow velocity reduces and starts again to fall, namely the junk fallen and cup 4 just enter in cup 4 to timing, maybe stir junk when the junk fallen meets with the cup hoof mouth 4b rotated with turntable intermittent to move toward cup center, in addition the support of the borehole wall, junk just enters smoothly in cup 4 to be formed and salvages, the mud entered in cup 4 leaks 7 by cup and enters in well.
