Description
Technical field
The utility model is used for coiled tubing provides a kind of downhole hardware of rotation when salvaging junk in the oil gas well for fishing tool, belong to the manufacturing technology field of industrial gas oil downhole tool.
Background technology
In the prior art, making common employing down-hole cartridge type wire rope fisher carry out fishing, is CN2580099 as publication number, and the Chinese patent literature that open day is on October 15th, 2003 discloses a kind of down-hole cartridge type wire rope fisher of salvaging the junk wire rope.One side constitutes continuous a plurality of zigzag barbs (B) in disjunctor (A) lower end, and the lower end is hard pointed cone (C), and each coupler body can constitute the two ends barb that makes progress.This special use fishing tool conical section bottom scribbles the YD alloy, can play the effect that grinding group opens passage of boring.Utilize opened passage, it is inner that assembly hook inserts steel wire group, repeatedly rotates the handling fishing string and can realize salvaging purpose.
And along with the development of technology, the coiled tubing fishing tool need not to trip out oil gas OIH pipe just can carry out operation.Coiled tubing is salvaged has a series of clear superiorities: to compare tensile strength higher with wire rope, can promote load greatly in operation; Coiled tubing has the hydraulic pressure circulation ability, can wash junk before salvaging.Compare with traditional workover rig, except that operating cost is low, also have advantages such as being convenient to install and saves time.Coiled tubing is in carrying out fishing, and fishing tool possibly can't be aimed at the down-hole fish, has brought difficulty to catching trouble of lost tool in hole.At this moment, fishing tool rotates to an angle, and favourable fishing tool is caught the down-hole fish.Coiled tubing can not be realized rotation, can make the hydraulic motor that has only of fishing tool rotation at present, but the hydraulic motor rotating speed is fast, uncontrollable rotational angle.
Summary of the invention
For solving the problems of the technologies described above, the utility model proposes a kind of coiled tubing and rotate fishing device with the down-hole, the utility model is rotatable fishing tool when carrying out fishing, and can control rotational angle.
The utility model is realized by adopting following technical proposals:
A kind of coiled tubing rotates fishing device with the down-hole, it is characterized in that: comprise carrying joint, swivelling pipe, elastic component and sleeve, the lower end of described sleeve connects the carrying joint, described carrying joint is passed in the bottom of swivelling pipe, elastic component is installed in the sleeve and an end of elastic component props up described swivelling pipe, run through to be provided with to rotate on the sidewall of described carrying joint and stir pin, have the J-shaped groove on the sidewall of swivelling pipe, described rotation is stirred pin and is placed in the described J-shaped groove.
Described swivelling pipe comprises step section and the diameter small rotation thread segment that diameter is bigger, and described step section contacts with carrying joint top, and described J-shaped groove is opened on the rotation thread segment below the step section.
Also include lower contact, the lower end of swivelling pipe is connected with lower contact.
Described elastic component is helical spring or rubber.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, the coiled tubing that adopts carrying joint, swivelling pipe, elastic component and sleeve to form rotates fishing device with the down-hole, and to compare tensile strength higher with wire rope, can promote load greatly in operation; Coiled tubing has the hydraulic pressure circulation ability, can wash junk before salvaging.Compare with traditional workover rig, except that operating cost is low, also have advantages such as being convenient to install and saves time.Simultaneously, rotation is stirred pin and is matched with the J-shaped groove, stirs moving up and down of pin by rotation and stirs the swivelling pipe rotation, thereby drive the fishing tool rotation.
2, in the utility model, swivelling pipe comprises step section and the diameter small rotation thread segment that diameter is bigger, the J-shaped groove is opened on the rotation thread segment below the step section, such form of structure, even under the effect of spring, rotation is stirred pin and also the step section of swivelling pipe can be withstood, thereby makes the position of swivelling pipe obtain fixing well.
Description of drawings
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments, wherein:
Fig. 1 is a structural representation of the present utility model
Fig. 2 stirs the structural representation that pin cooperates for J-shaped groove on the swivelling pipe with rotation
Mark among the figure:
1, lower contact, 2, the carrying joint, 3, rotation stirs pin, 4, swivelling pipe, 5, spring, 6, sleeve, 7, the J-shaped groove.
The specific embodiment
Preferred forms of the present utility model is as follows: referring to accompanying drawing, the utility model is stirred pin 3, swivelling pipe 4, spring 5 and sleeve 6 and is formed by lower contact 1, carrying joint 2, rotation.
Erection sequence of the present utility model is: carrying joint 2 is sleeved on swivelling pipe 4 outsides, swivelling pipe 4 upper step are contacted with carrying joint 2 upper surfaces, rotation is stirred pin 3 and is installed in the special-purpose pin hole of carrying joint 2 sides by screw thread, rotation is stirred in the J-shaped groove that pin 3 afterbodys place swivelling pipe 4, and swivelling pipe 4 lower ends are connected with lower contact 1 by screw thread.Spring 5 is installed in the sleeve 6, and sleeve 6 lower ends and carrying joint 2 upper ends are by being threaded.
During fishing, sleeve 6 tops are connected with coiled tubing, and lower contact 1 is connected with fishing tool by screw thread.Coiled tubing is sent into the utility model and fishing tool in the oil gas well, fishing tool be hampered after trouble of lost tool in hole contacts, make lower contact 1 and swivelling pipe 4 be obstructed equally and can not move down.Continue to transfer coiled tubing, sleeve 6 and carrying joint 2 move down together, and driven rotary is stirred the moving fortune of pin 3 downwards.Rotation is stirred pin 3 and is in the swivelling pipe J-shaped groove 7, and pin moves downward and will stir swivelling pipe 4 half-twist in the direction of the clock, and spring is compressed simultaneously.On carry coiled tubing, when sleeve 6 and carrying joint 2 move upward, under the effect of spring force, the fishing tool that swivelling pipe 4, lower contact 1 are connected with the bottom still closely contacts with trouble of lost tool in hole, when carrying joint 2 driven rotary are stirred pin 3 and moved upward, will stir swivelling pipe 4 equally by turning clockwise 90 °.The velocity of rotation of swivelling pipe 4 is put speed control by putting on the coiled tubing, on put and put twice coiled tubing and can realize that swivelling pipe 4 clockwise rotates a week, rotate a week thereby drive fishing tool.When fishing tool rotate to junk to timing, just can catch junk.
As a better embodiment of the present utility model be: a kind of coiled tubing rotates fishing device with the down-hole, comprise carrying joint 2, swivelling pipe 4, elastic component and sleeve 6, the lower end of described sleeve 6 connects carrying joint 2, described carrying joint 2 is passed in the bottom of swivelling pipe 4, elastic component is installed in the sleeve 6 and between sleeve 6 inwall tops and swivelling pipe 4, on the sidewall of described carrying joint 2, run through to be provided with to rotate and stir pin, have J-shaped groove 7 on the sidewall of swivelling pipe 4, described rotation is stirred pin 3 and is placed in the described J-shaped groove 7.Described swivelling pipe 4 comprises step section and the diameter small rotation thread segment that diameter is bigger, and described step section contacts with carrying joint 2 tops, and described J-shaped groove 7 is opened on the rotation thread segment below the step section.Also include lower contact 1, the lower end of swivelling pipe 4 is connected with lower contact 1.Described elastic component rubber.
