Description
Technical field
This utility model is related to oil well technology, and especially a kind of hydraulic active clamps fishing tool.
Background technology
Traditional tubing fishing tool is mainly used in the salvaging of steel oil pipe, is broadly divided into according to version difference：Cone
Class fishing tool, lance class fishing tool and cylinder class fishing tool.Cone class fishing tool is by the endoporus or outer wall of oil pipe
Being salvaged, due to the construction featuress of non metal continuous oil pipe, its inner liner and external protection material are that polyethylene is strong to thread making
Degree is relatively low thus cannot be salvaged using this kind of mode.Lance class fishing tool and cylinder class fishing tool are all by certainly by internal slide block
Weight slide downward, slide block produces relative displacement, is salvaged endoporus or outer wall that slide block bites junk, due to non-gold with inclined-plane
Category coiled tubing is multilamellar non-stick junction structure, and tubing can slide between layers, and such fishing tool cannot be formed enough
Radial force overcoming tubing slip between layers, the disengaging of external protection or inner liner can be caused, thus cannot adopt
This kind of mode is salvaged.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic active clamping fishing tool, can be used for traditional oil pipe and non-gold
The salvaging of category coiled tubing, has filled up the domestic blank without such pipes dragging tools, has promoted non metal continuous oil pipe
Using and development.
The purpose of this utility model can be realized by following technical solution：
A kind of hydraulic active clamps fishing tool, including cylinder tube, cylinder rod, salvaging outer tube, salvaging inner core, clamping
Inner sleeve, clamping overcoat, inside cylinder tube, the salvaging inner core is salvaging outer barrel, the clamping inner sleeve to the cylinder rod
In clamping jacket internal, the salvaging outer tube upper end connects cylinder tube, lower end connection clamping overcoat, the salvaging inner core upper end company
Connect cylinder rod, lower end connection clamping inner sleeve.
The purpose of this utility model can also be realized by following technical solution：
The clamping outer wall of inside race adopts the cone match of identical taper with clamping outer casing inner wall.
The clamping inner sleeve is four valve structures, and in clamping set upper side with salvaging inner core lower end by the way of abutting.
The fishing tool salvages inner core and the circumferential surface of salvaging outer tube is provided with through hole.
The circumferential surface for salvaging outer tube is evenly equipped with four and clamps and inner sleeve and make clamping inner sleeve open latus rectum for embedded
Maximum rectangle hollow out window.
The clamping overcoat lower end connection guide shoe, the lower surface of guide shoe is helical form, and inner surface is with taper.
This utility model has the advantages that：
It is safe and reliable with simple to operate, the advantages of applied widely.Can be used for conventional steel oil pipe and nonmetallic continuous
The salvaging of oil pipe, has filled up vacancy of the domestic non metal continuous oil pipe without fishing tool.
Description of the drawings
Fig. 1 is the structural representation of this utility model embodiment.
In figure：Tubing nipple 1, cylinder tube 2, cylinder rod 3, salvaging outer tube 4, salvaging inner core 5, clamping inner sleeve 6, clamping overcoat
7th, guide shoe 8, oil well casing 9, non metal continuous oil pipe 10.
Specific embodiment
Relevant detailed description of the present utility model and technology contents, coordinate description of the drawings as follows, but accompanying drawing only provides ginseng
Examine and purposes of discussion, not for being any limitation as to this utility model.
According to Fig. 1, a kind of hydraulic active clamps fishing tool, including cylinder tube 2, cylinder rod 3, salvaging outer tube 4, salvaging
Inner core 5, clamping inner sleeve 6, clamping overcoat 7, the cylinder rod 3 inside cylinder tube 2, salvaging in outer tube 4 by the salvaging inner core 5
Portion, inside clamping overcoat 7, the salvaging outer tube upper end connection cylinder tube, lower end connection clamps overcoat to the clamping inner sleeve 6,
The salvaging inner core upper end connection cylinder rod, lower end connection clamping inner sleeve.The clamping outer wall of inside race and clamping outer casing inner wall are adopted
With the cone match of identical taper.The clamping inner sleeve 6 is four valve structures, and set upper side is adopted with inner core lower end is salvaged in clamping
With the mode for abutting.The circumferential surface of the salvaging inner core and salvaging outer tube is provided with through hole.The circumference table for salvaging outer tube 4
Face be evenly equipped with four for be embedded in clamping inner sleeve and make clamping inner sleeve open latus rectum maximum rectangle hollow out window.Outside the clamping
Set lower end connection guide shoe 8, the lower surface of guide shoe is helical form, and inner surface is with taper.
Actively to clamp, with power set, wherein cylinder rod 3 is connected the fishing tool with inner core 5 is salvaged, cylinder tube
2 are connected with outer tube 4 is salvaged.By pressurizeing in the oil pipe to cylinder tube afterbody, hydraulic driving oil cylinder bar and salvaging inner core are downward
Motion drives the inside undergauge of clamping inner sleeve so as to clamp the pipeline fallen in well.
Wherein described fishing tool carries power set, and the afterbody of cylinder tube 2 is connected by tubing nipple 1 with oil pipe,
The lower end of cylinder tube 2 is connected with salvaging outer tube 4 and clamping overcoat 7, and cylinder rod 3 is connected with salvaging inner core 5 and clamping inner sleeve 6.
