Abstract

The utility model belongs to a tool for repairing damaged casings of oil and water wells in oil fields, in particular relates to a liner tube strengthening bonded repairing tool, which comprises an upper tie-in , a shearing pin, a cylinder liner, a cylinder packing ring, a plunger, a plunger packing ring, a tail cylinder, a draw rod, a tow tube, an upper expander probe, a collar, a centre draw rod, sealers, a bonded repairing liner tube, a lower expander probe, a tail tow, a shearing ring, and a screwed plug. The special aspects of the utility model are as following: two sealers are connected on two ends of the bonded repairing liner tube, wherein the sealers adopt sealing groove type sealing band structure, the upper expansion probe, and the lower expansion probe, are respectively enchased on one end of the two sealers, the other end of the lower expansion probe, and the shearing ring are engaged with each other and support each other, an end portion of the lower expansion probe adopts a multi flap type structure, the shearing ring adopts a multi flap shear wall type structure. The tool of the utility model has the beneficial effects of reliable sealing, big hanging force, compact structure, safety, and conciseness.

Description

Bushing pipe is reinforced the instrument that subsidizes
Technical field
The utility model belongs to the damaged sleeve pipe fix tool of oilfield oil well, and particularly a kind of bushing pipe is reinforced the instrument that subsidizes.
Background technology
At present, the instrument that subsidizes of the damaged sleeve pipe reparation of oilfield oil well, there is bellows-type to subsidize instrument, explosion type and subsidizes the casing patch workover tool that instrument, hydraulic expanding tube formula subsidize a lot of types such as instrument, hydraulic expanding tube formula casing patch instrument is the most frequently used workover tool, but its sealing of the instrument of existing various structures and releasing gadget have incomplete one side, it is incomplete to be restrictions such as the success rate of the technology inner surface fineness that is subjected to sleeve pipe, ovality, can't obtain large-area application so casing reinforcement subsidizes technology in the oil field.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of bushing pipe to reinforce the instrument that subsidizes, this bushing pipe is reinforced the instrument that subsidizes, top connection links to each other with oil pipe or drilling rod on the oil well, down to the interior precalculated position of the oil-water well that is full of liquid, pitching is suppressed, by top connection, cut off pin, cylinder sleeve, cylinder liner packing ring, plunger, the plunger seal circle, the tail cylinder is formed fluid cylinder, produce downward thrust, along with the tube chamber internal pressure progressively raises, fluid cylinder thrust increases, when reaching the certain pressure value, cutting off pin cuts off, plunger and cylinder sleeve generation relative motion, under the effect of power, go up bloated and a bloated sealer of a branch don't push that expands down, the sealer outside is embedded in the well inner sleeve, realize sealing and suspension, continue to suppress, shearing ring interacts with the head that expands down, many lobes shear wall of shearing ring is cut off, the instrument release, at this moment, subsidize bushing pipe, sealer, go up bloated head and tightly mesh together with following casing patch completion tubular column and the oil-water well inner sleeve that expands the head composition, bushing pipe is reinforced other parts that subsidize in the instrument and is separated with completion tubular column, on carry, finish casing reinforcement and subsidize process, because closed closure tape construction is adopted in the sealer outside, internally finish is high or have the Casing Failure reparation of certain ovality to subsidize, good sealing effect, following bloated head, tail holder and shearing ring are formed releasing gadget, and shearing ring adopts many lobes shear wall structure, have solved the conventional instrument unreliable problem of giving up.
The technical scheme in the invention for solving the technical problem is: a kind of bushing pipe is reinforced the instrument that subsidizes, by top connection, cut off pin, cylinder sleeve, cylinder liner packing ring, plunger, the plunger seal circle, the tail cylinder, pull bar, trustship, go up the head that expands, box cupling, center pull rod, sealer, subsidize bushing pipe, following bloated head, the tail holder, shearing ring, plug is formed, its special character is: connect two sealers at the two ends of subsidizing bushing pipe, sealer adopts closed pockets formula closure tape construction, go up bloated head and inlay an end that withstands on two sealers respectively with the head that expands down, the other end of bloated head withstands on the shearing ring cooperation down, the afterbody of bloated head adopts the multi-clove type structure down, and shearing ring adopts many lobes shear wall formula structure.
The beneficial effects of the utility model are: sealing is reliable, and suspension force is big, the entire tool compactness, safety is succinct.
Description of drawings
Accompanying drawing is a schematic diagram of the present utility model.
In the accompanying drawing: top connection 1, cut off pin 2, cylinder sleeve 3, cylinder liner packing ring 4, plunger 5, plunger seal circle 6, tail cylinder 7, pull bar 8, trustship 9, go up expand 10, box cupling 11, center pull rod 12, sealer 13, subsidize bushing pipe 14, expand 15 down, tail holder 16, shearing ring 17, plug 18.
The specific embodiment
An embodiment is described in conjunction with the accompanying drawings:
In the Figure of description: top connection 1 directly links to each other with drilling rod or oil pipe in the oil-water well, by top connection 1, cut off pin 2, cylinder sleeve 3, cylinder liner packing ring 4, plunger 5, plunger seal circle 6, tail cylinder 7 is formed multistage fluid cylinder, begin to be followed successively by a plurality of plungers 5 from top connection 1, pull bar 8, box cupling 11, center pull rod 12, tail holder 16, shearing ring 17, plug 18 screwed connections together, a plurality of cylinder sleeves 3 are enclosed within on the plunger 5, tail cylinder 7 is enclosed within on the pull bar 8, trustship 9 one ends and 7 screwed connections of tail cylinder, the other end withstands on last 10 edge that expand, subsidizing the two ends of bushing pipe 14 and two sealer 13 screwed connections forms together and subsidizes pipe, and go up to expand 10 with expand down 15 respectively edge withstand on the two ends of subsidizing pipe, the other end of the head that expands down cooperates with shearing ring 17 and withstands on.
