Description
Technical field:
The utility model relates to a kind of oil drilling fishing tool, in particular to a kind of hydraulic fishing tool of tackling all problems at once.
Background technique:
During wellbore construction and underground work, trouble of lost tool in hole is often resulted in due to misoperation etc., including fall
The small falling objects such as gear wheel, pincers tooth, nut, hand-held tool, pin.Therefore, it is necessary to fishings, and salvaging trouble of lost tool in hole is one important
Measure.Specific purpose tool must be used, and scene is to tackle all problems at once to beat commonly using the special fishing tool for salvaging underground small falling object
Fishing combined tool.The fishing tool is essentially all according to situation self manufacture in well, using suitably sized casing, according to fish feelings
Condition design, determines the width of each pawl, thickness and length, is completed with gas welding system, poor reliability and accuracy are inadequate.The salvaging
Tool making and easy to operate, but it is low to salvage junk success.The main reason is that pressurization is difficult to control when (1) uses, it can not be more
Pressure, pushing pawl can excessively be broken, not only fish out less than junk, increase junk instead, can not also push it is very few, certain pawls even it is complete
The deformation of portion's pawl not enough, equally can not engagement with the fish.(2) use is by the soft or hard limitation in stratum, tool pressurization, it is desirable that shaft bottom cannot be too
It is soft, otherwise pawl can not be bent, so that junk can not be fished out.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of hydraulic fishing tools of tackling all problems at once, and the arrangement achieves logical
Crossing mud pressure makes junk handgrip is reliable and stable to catch junk, and salvaging effect is good, and tool is adapted to soft or hard stratum, passes through on ground
Monitoring standpipe pressure value variation judge handgrip whether effective action, avoid error in judgement, cause multiple trips tool repetition
Salvaging and milling operation, can reuse, and handgrip is replaceable, easy to operate, securely and reliably.Overcome existing salvaging of tackling all problems at once
Pressurization is difficult to control when tool uses, and salvaging effect is poor, uses the deficiency by the soft or hard limitation in stratum.
Technical solution adopted in the utility model is: a kind of hydraulic fishing tool of tackling all problems at once, including outer main body；Outer main body
Inside is equipped with hydraulic cylinder, and the design of hydraulic cylinder lower end has pressurization cylinder, and the design of pressurization cylinder lower end has finger catcher, and designing in outer main body has
Be connected to the by-pass prot inside outer main body upper end and outside outer lower body, in outer main body design have the outer lower body inside of connection with
Reflux hole outside outer main body upper end, design has the relief hole for being connected to outer inside and outside of the main body in outer main body, and relief hole is by hydraulic potting
Stifled, hydraulic cylinder can unseal relief hole after moving down, and outer main body bottom end design has cutting blade, connect and lead on outer lower body inner wall
Xiang Ti, when finger catcher downlink, can be bent along guide way and form a circular closure bottom surface.
Finger catcher is designed to the split-type handgrip of replacement.
Guide way is connected by screw on outer lower body inner wall.
Keep junk handgrip reliable and stable by mud pressure the beneficial effects of the utility model are: the utility model is realized
Junk is caught, salvaging effect is good, and tool is adapted to soft or hard stratum, judges handgrip by the variation of monitoring standpipe pressure value on ground
Whether effective action, avoid error in judgement, cause multiple trips tool repeat salvage and milling operation, can reuse,
Handgrip is replaceable, easy to operate, securely and reliably.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram of by-pass prot, reflux hole and relief hole.
Fig. 3 is that hydraulic cylinder moves down schematic diagram.
Fig. 4 is the structural schematic diagram of guide way and cutting blade.
Fig. 5 is schematic diagram when the utility model is used.
Specific embodiment:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of hydraulic fishing tool of tackling all problems at once, including outer main body 1；Inside outer main body 1
Hydraulic cylinder 2 is installed, the design of 2 lower end of hydraulic cylinder has pressurization cylinder 3, and the design of pressurization 3 lower end of cylinder has finger catcher 4, designs in outer main body 1
Have a by-pass prot 6 being connected to inside outer 1 upper end of main body and outside outer 1 lower end of main body, by-pass prot 6 be for prevent from suppressing after pitching pump with
Shaft bottom reacting cycle runner, design has the reflux hole 8 being connected to inside outer 1 lower end of main body and outside outer 1 upper end of main body in outer main body 1,
Circulating mud from by-pass prot 6 is from bottom by returning on reflux hole 8.Design has letting out inside and outside the outer main body 1 of connection in outer main body 1
Hole 9 is pressed, relief hole 9 is blocked by hydraulic cylinder 2, and hydraulic cylinder 2 can unseal relief hole 9 after moving down, and 2 downlink of hydraulic cylinder passes through pressure release
Hole 9 is vented mud pressure in drilling tool.Outer 1 bottom end of main body design has cutting blade 5, and cutting blade 5 is used for tool rotary cutting stratum, outside
Guide way 10 is connected on 1 lower end inner wall of main body, can be bent along guide way 10 when 4 downlink of finger catcher and form a circular closure
Bottom surface.
Finger catcher 4 is designed to the split-type handgrip of replacement.
Guide way 10 is connected on outer 1 lower end inner wall of main body by screw 11.
As shown in figure 5, in use, being opened under bottom end to be connected to the drill assembly of the utility model to away from shaft bottom 2-3m or so
Pump normal circulation mud, while arriving shaft bottom for drilling tool is slowly lower, when away from shaft bottom 1m in discharge capacity circulating mud, flushing manhole bottom 3-5
Minute, then stop circulation, above propose drilling tool 3-5m continuation huge discharge circulation and shaft bottom desilting was recycled to top hole in 3-5 minutes,
Termination of pumping arrives shaft bottom, the light bit pressure rotary tools set milling drilling 0.1m of slow speed or so for tool is slowly lower, and the ball 7 that builds the pressure is thrown in drilling rod,
Small displacement recycles release, and when being pumped raising, ball has been taken a seat, and the ball 7 that builds the pressure, which blocks hydraulic cylinder slurry channel, to be made to generate mud in drilling tool
Slurry pressure pushes hydraulic cylinder 2 to move down, and steps up discharge capacity at this time, pump pressure variation is paid attention to, when pressure declines suddenly, it has therefore proved that
4 execution of finger catcher, then termination of pumping carries out trip-out operation.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
