Abstract
The invention discloses underground cable coupler, including body, top connection, lower contact, the body offers off-centre operation cylindrical passageway, the top connection lower end is threadedly attached in body interior cylindrical channel upper end, the lower contact upper end is threadedly attached in body interior cylindrical channel bottom, described body sidewall opens up connecting groove, opened up from body top to connecting groove for the main line through hole through main cables, opened up from body bottom to connecting groove for the separated time through hole through separated time cable.The outer body is cased with overcoat, and the connecting groove of this body sidewall is closed into an annular seal space by overcoat.The present invention is branched off into many cables by single line cable, solve the problems, such as to be corresponded to when the downhole tool of same oil gas water well is more many cables from well head to underground, save cable expense expenditure, mitigate live artificial construction's intensity, manpower demand is reduced, is also convenient for carrying out on-site cable branch in oil gas water well job site.
Description
Technical field
The present invention relates to cable tapping device, specifically underground cable coupler.
Background technology
Constantly promoted as oil field development is intelligent, the exploitation to oil gas water well requires also more and more higher, and it is right to specially require
Oil gas water well carries out fine accurate seperated layer water injection, oil production by layer and zonal testing.In order to reach these targets, usually require that down
Liquid controling pipe line, capillary tubing, optical fiber, special cable etc. control the various instruments in underground.In this kind of downhole tool running, it is necessary to
Connect correspondence cable respectively to be controlled, when the downhole tool of same oil gas water well is more, due to oil gas water well job site
Particular surroundings, does not allow to carry out on-site cable branch welding etc., and the cable from well head to underground also accordingly increases, cable cost
With height, difficulty of construction is larger.
The content of the invention
It is an object of the invention to provide underground cable coupler, section only needs single line cable from well head to downhole tool,
Underground cable coupler is connected during branch, many cables are branched off into by single line cable, solve above technical barrier.
In order to reach above-mentioned purpose, present invention employs following technical scheme, underground cable coupler, including body, on
Joint, lower contact, the body offer off-centre operation cylindrical passageway, and the top connection lower end is threadedly attached in body interior
Cylindrical channel upper end, the lower contact upper end is threadedly attached in body interior cylindrical channel bottom, described
Body sidewall opens up connecting groove, is opened up from body top to connecting groove for the main line through hole through main cables, from body bottom to
Connecting groove is opened up for the separated time through hole through separated time cable.
The main line through hole is consistent with the mutual axis of separated time through hole, while equal with the axis of off-centre operation cylindrical passageway
OK.
Being provided with sealing nail pressing through the porch of main line through hole, the separated time cable leads to passing separated time the main cables
The exit in road is also equipped with sealing nail pressing.
The outer body is cased with overcoat, and the connecting groove of this body sidewall is closed into an annular seal space by overcoat.
Stop pin is provided between the overcoat and body.
Sealed by sealing ring between the body and overcoat.
Compared to prior art, the invention has the advantages that：
Underground cable coupler, can not carry out the welding of on-site cable branch in oil gas water well job site, by connection
Underground cable coupler, many cables are branched off into by single line cable, and it is right that the downhole tool of the same oil gas water well of solution is needed when more
Many cable problems that should be from well head to underground, save cable expense expenditure, mitigate live artificial construction's intensity, reduce labour
Need, be also convenient for carrying out on-site cable branch in oil gas water well job site.The invention has the advantages that：Component parts structure
Simply, it is easily worked manufacture, device to be easily assembled to, rapid operation.

Specific embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings it is as follows, but accompanying drawing only provide reference with
Purposes of discussion, not for being any limitation as to the present invention.
As shown in figure 1, underground cable coupler, including body 4, top connection 1, lower contact 9, the body offers bias
Cylindrical channel, the top connection lower end is threadedly attached in body interior cylindrical channel upper end, in the lower contact
End be threadedly attached in body interior cylindrical channel bottom, described body sidewall opens up connecting groove, from body top to
Connecting groove is opened up for the main line through hole through main cables 2, is opened up from body bottom to connecting groove for dividing through separated time cable 8
Line three-way hole.The main line through hole is consistent with the mutual axis of separated time through hole, while equal with the axis of off-centre operation cylindrical passageway
OK.The outer body is cased with overcoat 6, and the connecting groove of this body sidewall is closed into an annular seal space by overcoat.The overcoat and sheet
Stop pin 5 is provided between body.Sealed by sealing ring 7 between the body and overcoat.The main cables are through master
The porch of line three-way hole is provided with sealing nail pressing 3, and the separated time cable is also equipped with sealing pressure in the exit for passing separated time passage
Nail.
Underground cable coupler is connected to the tubing string position that need to carry out cable branch when using, and divides from well head to underground cable
The main cables 2 for connecing device are connected by sealing nail pressing 3 with body 4, and the separated time cable 8 below underground cable coupler is by sealing nail pressing
3 are connected with body 4, and sealing nail pressing 3 is connected by screw thread with body 4 and sealed, and main cables 2 connect with the internal wiring of separated time cable 8
Joint is installed between body 4 and overcoat 6, can not be influenceed by extraneous oil gas water, overcomes pit shaft high pressure to disturb, main cables 2 with point
Cable 8 connect it is intact after tighten overcoat 6 again, body 4 prevents from loosening with overcoat 6 by stop pin 5, and body 4 passes through close with overcoat 6
The fitted seal of seal 7.The present invention has component parts simple structure, is easily worked manufacture, device and is easily assembled to, rapid operation
Advantage.
Presently preferred embodiments of the present invention is the foregoing is only, is not used to limit the scope of the claims of the invention, other are with this
The equivalence changes of the patent spirit of invention, all should all belong to the scope of the claims of the invention.
