The present invention provides a kind of steel pipe type cable traversing device, including upper joint sleeve, lower joint sleeve, upper sleeve through, under wear, the upper sleeve through wears to offer under axially penetrates through hole for what steel pipe type cable passed through, the upper sleeve through lower end is connected through a screw thread with upper joint sleeve, the upper joint sleeve lower end is connected through a screw thread with downhole tool upper end, the downhole tool lower end is connected through a screw thread with lower joint sleeve upper end, and union is installed outside the lower joint sleeve, is worn under the connection of union lower end.The upper joint sleeve, lower joint sleeve, inside downhole tool by inner tube across and constitute double wall space inner tube, the double wall space and upper sleeve through, under wear the hole that axially penetrates through opened up and be connected.The present invention is mounted on the both ends of original downhole tool, realizes cable penetration, can save the redesign of cable downhole tool, especially for the complicated downhole tool such as packer, can greatly improve efficiency of research and development and product development cycle.
Description
Technical field
The present invention relates to field of oil field oil extraction to be layered measure and control device, especially a kind of steel pipe type cable traversing device.
Background technique
As separate water injection well measuring and regulating method is complete by traditional retrievable type survey reconciliation memory-type survey tuning automation, intelligence
Well direction is developed, and intelligent Well Completion comes into being.The technology connects the single or multiple water filling layer positions in underground by carrier of cable
Survey water flow regulator, realize seperated layer water injection parameter real time monitoring and therefore the on-line automatic adjusting of layered waterflooding quantity connect with casing
The downhole tool of touching, such as packer, hydraulic anchor, hydraulic slip are both needed to have cable penetration function.For this purpose, providing one kind
Cable penetration device is crossed, realizes the cable penetration of downhole tool.
Summary of the invention
The object of the present invention is to provide a kind of steel pipe type cable traversing device, which is mounted on the two of original downhole tool
End realizes cable penetration, the redesign of cable downhole tool can be saved, especially for the complicated well such as packer
Lower tool, can greatly improve efficiency of research and development and product development cycle.
The purpose of the present invention can be achieved by the following technical measures:
A kind of steel pipe type cable traversing device include upper joint sleeve, lower joint sleeve, upper sleeve through, under wear, the upper sleeve through
Upper offer is worn under and axially penetrates through hole for what steel pipe type cable passed through, and the upper sleeve through lower end and upper joint sleeve pass through screw thread
Connection, the upper joint sleeve lower end are connected through a screw thread with downhole tool upper end, on the downhole tool lower end and lower joint sleeve
End is connected through a screw thread, and union is installed outside the lower joint sleeve, is worn under the connection of union lower end.
The purpose of the present invention can be also achieved by the following technical measures:
The upper joint sleeve, lower joint sleeve, inside downhole tool by inner tube across and constitute folder inner tube
Wall space, the double wall space and upper sleeve through, under wear the hole that axially penetrates through opened up and be connected.
It the steel pipe type cable and axially penetrates through sealing, soft metal is realized by pressure cap and soft metal sealing element between the inner wall of hole
The axial inner ends face of pressure cap is arranged in sealing element.
Upper end is worn under described and union is connected through a screw thread and limits lower joint sleeve axial movement.
The upper sleeve through upper end connects top connection, under wear lower end connection lower contact, said inner tube upper and lower end faces are withstood on
Between top connection lower end surface and lower contact upper surface.
The invention has the following advantages:
1, cable is passed through via the annular space between the central tube of downhole tool and the pipe of cable penetration device excessively, and pipe uses
Eccentric structure, guarantee there are enough interior latus rectums to carry out section plane test, flow rate test, thus guarantee downhole tool properties and
Function is unaffected；
2, cable uses steel pipe type cable, effective sealing of cable and passage lanes easy to accomplish；
3, it crosses cable penetration device and has union function, effectively avoid that cable distortion is caused to be spiraled in installation process；
4, cable uses soft metal realization is reliable to seal with cable penetration device is crossed, easy installation and reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
In figure: 1- top connection；2- steel pipe type cable；3- pressure cap；The soft metal 4- sealing element；5,7- sealing ring；6- upper sleeve through；8-
Upper joint sleeve；9- inner tube；10- lower joint sleeve；11- union；It is worn under 12-；13- lower contact.
Specific embodiment
Detailed description for the present invention and technology contents, cooperation Detailed description of the invention it is as follows, however attached drawing only provides reference with
Purposes of discussion is not intended to limit the present invention.
According to Fig. 1, which includes that 1 lower end of top connection is connected through a screw thread with 6 upper end of upper sleeve through, institute
It states and offers one on upper sleeve through 6 and axially penetrate through hole for what steel pipe type cable passed through, the steel pipe type cable and axially penetrate through hole inner wall
Between sealing realized by pressure cap 3 and soft metal sealing element 4.The upper sleeve through lower end is connected through a screw thread with upper joint sleeve 8, institute
8 lower end of upper joint sleeve is stated to be connected through a screw thread with downhole tool upper end.The downhole tool lower end and 10 upper end of lower joint sleeve are logical
Threaded connection is crossed, wears 12 and union 11 under installing outside the lower joint sleeve 10,12 upper ends are worn under described and union 11 is logical
It crosses and is threadedly coupled and limits lower joint sleeve axial movement.Lower end is worn under described to connect with lower contact 13.The upper joint sleeve, under
Inner tube 9 is installed inside connector sleeve and downhole tool and constitutes double wall space, said inner tube is installed between top connection and lower contact.
Upper joint sleeve is arranged sealing ring between upper sleeve through, top connection respectively, lower joint sleeve respectively and under wear, be arranged between lower contact
Sealing ring.The hole axial direction through hole and double wall space that the steel pipe type cable is worn under by upper sleeve through realize downhole tool
Cable penetration.
The foregoing is merely presently preferred embodiments of the present invention, non-to limit the scope of the patents of the invention, other are with this
The equivalence changes of the patent spirit of invention should all belong to the scope of the patents of the invention.
