Abstract
The utility model discloses an internal centering and buckling centering device. The internal centering and buckling centering device comprises an inner tube inserted in a tubing pup joint, wherein the inner tube is connected to the tubing pup joint through tightening screws; and a baffle ring is arranged above the inner tube. As the inner tube inserted in the tubing pup joint is adopted to guide the centering, the internal centering and buckling centering device, disclosed by the utility model, has the advantages of efficiently preventing wrong buckling during the buckling process, improving buckling effect and being simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of instrument of setting upright, and particularly relates to a kind of make-up centralizer that make-up is salvaged in the oil gas well that is used for.
Background technology
At present, in sleeve pipe, carry out make-up when salvaging, because the fish size is less than casing inner diameter, so fish is not placed in the middle in well, during make-up, the normal thread alternating of tubing thread makes that the make-up effect is bad, can not satisfy the requirement that lifts energetically.At present main solution has two kinds: 1) carry out according to refloating operation's teacher experience; 2) according to working specification, qualitative construction.At present also do not have a kind of make-up of special use to set upright instrument, have influence on the enforcement of make-up fishing process, the oil pipe make-up is easy to thread alternating when salvaging, and salvages its bonding strength of joint screw thread damage back and does not reach requirement, causes correlated parts to scrap, and salvages cost and improves.So need a kind of make-up centralizer of design.
The utility model content
The utility model provides and sets upright the make-up centralizer in a kind of for solving the technical problem that exists in the known technology, and thread alternating when this centralizer can effectively prevent make-up improves the make-up effect.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: set upright the make-up centralizer in a kind of; Comprise the interior pipe that is inserted in the tubing nipple; Pipe is connected on the said tubing nipple through holding out against screw in said, and said interior pipe top is provided with baffle ring.
The said screw that holds out against is a sunk screw.
Advantage and the good effect that the utlity model has are: adopt the interior pipe guiding that is inserted in the tubing nipple to set upright, thread alternating in the time of effectively preventing make-up improves the make-up quality; And simple in structure, easy to use, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, connect oil pipe, 2, tubing coupling, 3, baffle ring, 4, tubing nipple, 5, hold out against screw, 6, interior pipe.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, set upright the make-up centralizer in a kind of, comprise the interior pipe 6 that is inserted in the tubing nipple 4, interior pipe 6 is connected on the tubing nipple 4 through holding out against screw 5, and interior pipe 6 tops are provided with baffle ring 3.The above-mentioned screw 5 that holds out against adopts sunk screw better.
The operating principle of the utility model:
During use; Interior pipe 6 is connected on the tubing nipple 4 through holding out against screw 5; Tubing nipple 4 through tubing coupling 2 be connected oil pipe 1 and connect, connect be positioned between oil pipe 1 and the tubing nipple 4 in baffle ring 3 above the pipe 6, connect oil pipe 1 and be connected bottom the fishing string.After interior pipe 6 was inserted into bottom fish oil pipe inner chamber, interior pipe 6 just can be set upright buckleing up and down of make-up oil pipe, and the realization make-up is set upright function, thereby prevents thread alternating.The position of pipe 6 in baffle ring 3 is used to limit.Hold out against screw 5 be used for preventing in pipe 6 in the going down process landing.After the make-up success, shift interior pipe 6 onto the tubing string deep like needs, can pound work to interior pipe 6 with the steel wire instrument from well head, shift interior pipe 6 onto the tubing string deep.
The make-up that the utility model can be used in the oil well is salvaged, and pipe inserts fish oil pipe inner chamber in adopting, and makes the fit clearance between them very little, and interior pipe can be set upright the oil pipe up and down of make-up well, the generation of thread alternating when preventing make-up.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
