The application of general scene.
Conventional coiled tubing perforating job can connect perforating gun in well head by root, is not limited by perforating gun length,
But coiled tubing perforating job can only be carried out under the conditions of kill-job.Longer in perforation span, especially coiled tubing perforation with pressure
Or under the conditions of coiled tubing wire transmission formula sub-clustering perforating job, due to perforating gun cannot be connected in well head by root, and continuously oil
Pipe there is hardness and cannot short distance bending, be badly in need of a kind of instrument improving perforation pipe string and coiled tubing ground-mounted efficiency or dress
Put.
In prior art, China Patent No. CN201320761960 discloses a kind of coiled tubing perforation with pressure flexible rotating
Lifting sub, publication date 2014-04-23.The universal joint top connection of this device, universal joint mandrel, universal joint lower contact order connect
Connect, universal joint lower contact lower end is passed through upper connection axostylus axostyle and connected flexible joint, flexible joint lower end is passed through lower connection axostylus axostyle and connected rotation
Pipe nipple top connection, rotating short-knot top connection, rotating short-knot mandrel, rotating short-knot lower contact, body of a gun adapter are linked in sequence.Should
Device quickly can be connected with perforator in the confined space, shorten and change the section time, reduce labor intensity, overcome existing lifting
The deficiency that pipe nipple cannot be connected with perforator in the confined space.
This device can meet the coiled tubing perforating job of routine, but cannot meet coiled tubing wire transmission formula sub-clustering
Perforation pressurization or signal transmission demand, and device length is longer, step change is more, there is certain potential safety hazard.
Content of the invention
The purpose of this utility model is the problems referred to above overcoming prior art to exist, and provides a kind of coiled tubing flexible rotation
Turn attachment means.This utility model can not need to be sequentially connected perforation pipe string in well head restricted clearance, only needs ground group to install
Coiled tubing is connected after the pipe string of composition shower hole.
For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of coiled tubing flexible rotating attachment means it is characterised in that：Including top connection, rotary shaft, rotating shaft joint,

Joint connects, rotating shaft joint, lower contact and shearing bolt composition 180 degree axial-rotation mechanism；Top connection, rotary shaft and rotation
Shaft coupling forms 360 degree of mechanisms that rotate in a circumferential direction.
The end of thread of described top connection is threadeded with rotary shaft.
Described rotating shaft joint is threadeded with rotary shaft and is fixed by tapping screw.
Described shearing screw bolt passes rotating shaft joint and lower contact are threadeded with lower contact and are passed through tapping screw
Fixing.
Using the utility model has the advantage of：
First, this utility model can achieve that 360 degree rotate in a circumferential direction and 180 degree axial-rotation is it is achieved that coiled tubing and sub-clustering
Perforation pipe string efficiently quickly connecting on ground.
2nd, this utility model tensile strength is high, highest specified resistance to tension 40T.
3rd, this utility model increased the flexibility of coiled tubing sub-clustering perforation pipe string, improves the handling capacity of pipe string, can
Upwarp in the complex hole condition perforating job such as section used in big dog-leg section or greatly.
4th, this utility model be applied to no cable coiled tubing sub-clustering perforating job technique it is adaptable to be added by pit shaft
The sub-clustering perforating job that pressure is ignited.
5th, this utility model structure is simple, and length is short, cylindrical no reducing substantially, improves the safety of perforating job.
6th, this utility model button-type is general, install convenient, be easily installed on 2 3/8TBG instruments or oil pipe it is adaptable to
Coiled tubing transmits sub-clustering perforation construction operation, convenient execute-in-place, has a extensive future.
