Description
Technical field
The invention belongs to oil well Cabling Components technical fields, are related to a kind of high pressure resistant anti-pulling electricity of high-temperature oil well
Cable joint.
Background technique
Current high-temperature oil well well known in the art is divided into tag and cable indirectly with high pressure resistant cable connector
Head is attached using rivet interlacement, the connection of bolt fastening pressing plate or hook shape connection type.The prior art be production structure and
The overall dimensions of big pulling capacity are limited, and cable connector slightly long is easy to appear that electric leakage and electric field occur because getting rusty is abnormal using the time
The problem of change, seriously affects cable normal use under high pressure；In addition, traditional cable connector is there is also having, structure is complicated, more
The changing-over head time is long, installation difficulty is big (because this cable connector is stopped work in drilling tool together tripping in deep-sea oil well
Replace the more wasteful time, and if cable construction personnel be laid with cable and when being attached to cable connector not strictly by
It is required that operation, it is easy to so that cable connector loosens in use for some time, influence cable communication), resist big pulling capacity
Performance is poor, oil liquid or the problems such as other corrosive media easy to leak.
Summary of the invention
It is an object of the invention to be solved to problem of the existing technology, provide a kind of production structure it is simple,
The high-temperature oil well that line is easy to operate, reliable sealing and service life is long and prevents the corrosive medias such as oil liquid from penetrating into is resisted with high pressure resistant
Drawing cable connector.
The technical solution used for achieving the above object is such that the resistance to height of provided high-temperature oil well
Pressure anti-pulling cable connector includes that the opposite single steel cylinder cable touched in two thin core end and one are sleeved on two single steel cylinder electricity
The connection sleeve of cable outer radial periphery is equipped with a nut in the outer radial periphery difference thread bush of the both ends cylinder of connection sleeve, respectively
An end of the nut far from the thin core of single steel cylinder cable is connected by retaining ring and sealing ring with the outer wall of single steel cylinder cable, each spiral shell
Cap is connected by retaining ring and sealing ring with sleeve outer wall is connect close to another end of the thin core of single steel cylinder cable, in connection sleeve
A ring compression block is inwardly respectively pressed by external along cylinder axial direction between two single steel cylinder cables.
High-temperature oil well provided by the invention is to the high pressure resistant electricity of conventional high-temperature oil well with high pressure resistant anti-pulling cable connector
The improvement of cable joint structure makes single steel cylinder cable in structure, connection sleeve and nut junction and uses sealing ring and gear
Circle separately uses ring compression block in single steel cylinder cable and nut coupling part, can cable connector be enable preferably to exist in this way
It is used under hyperbaric environment.Compared with prior art, the present invention replaces tradition with simple ring compression block, sealing ring and retaining ring
Riveted joint structure, considerably simplify cable connector manufacture structure, extend use the time, improve total
Leakproofness, can determine square connection realize quota pulling capacity, be allowed to connect under big pulling capacity it is relatively reliable, it is practical, can have
Effect prevents the case where influencing wired signal transmission because of the infiltration of the corrosive medias such as oil liquid appearance, makes the replacement operation of connector more
It is convenient.

Specific embodiment
It is described further below with reference to attached drawing technical solution in the embodiment of the present invention.Based on the reality in the present invention
Example is applied, every other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the scope of protection of the invention.
Referring to attached drawing, the high pressure resistant anti-pulling cable connector of high-temperature oil well of the present invention mainly includes single steel cylinder electricity
Cable, connection sleeve and nut three parts.Overall structure of the invention uses symmetrical structure, and component includes the first single steel cylinder electricity
Cable 2 and the second single steel cylinder cable 1, connection sleeve 3, the first nut 15 and 13, four the second nut 10, ring compression block standards
Part O-ring seal (16,8,6,11) and four standard component retaining rings (17,9,7,12).Second single steel cylinder cable 1 and the second spiral shell
10 one end of cap by being connected by the 4th sealing ring 11 with fourth gear circle 12 while using ring compression block 13, the second nut 10
The other end with connect 3 one end of sleeve and be connected by third sealing ring 6 and third retaining ring 7, connect the other end and the first spiral shell of sleeve 3
15 one end of cap is connected by the second sealing ring 8 with the second retaining ring 9, the other end of the first nut 15 and the first single steel cylinder cable 2
It is connected by the first sealing ring 16 first with retaining ring 17 while uses ring compression block 13.
In specific connection application, the characteristics of which realizes specified pulling capacity using torque wrench, make
When with ring compression block, so that still retaining screw thread inside ring compression block, in order to facilitate the dismounting of ring compression block
(because pressing force is very big, being difficult to carry out dismantling annular compact heap by common tool, can only be dismantled by screw thread),
Under ring compression block, component is carried out under high pressure using such to effectively reduce conventional coupling arrangement bring
