Description
Technical field
The present invention relates to mechanical oil production technology technical field, a kind of oil-submersible cable wet type connection method and its dress are especially belonged to
It sets.
Background technique
In technical field of mechanical oil extraction, oil-submersible cable wet connection is to realize that big flat cable is connected with small flat cable
Tool has a major impact cable transfer performance, service life and security performance.A kind of existing righting of patent CN104852342A
Formula underground cable protector is realized pair in such a way that solid connects by way of increasing and adding cable trough on the inside of tubular body
Cable connection, the disadvantage is that complicated for operation, installation takes a long time, especially winter installs poor feasibility, while being easy by oil, gas cut
Erosion.Novel submersible cable wet connection is designed using plug-in type, realizes sharp work, and using the wet type of insulation oil liquid
Sealing means can be effectively isolated oil, gas cut erosion.
Summary of the invention
The object of the present invention is to provide can isolate threephase cable, it is wet to be effectively isolated oil, a kind of oil-submersible cable of gas cut erosion
Formula connection method and its device.
Technical scheme is as follows: a kind of novel submersible cable wet connection is by small flat cable plug, connection
Screw, cable connecting arrangement, relief valve, decompression protection capsule, clip, slope limiter, big flat cable plug, limited screw and
Feed liquor pressure retaining valve composition；Its medium and small flat cable plug is connected with cable connecting arrangement by connecting screw, cable connecting arrangement and
Relief valve is threadedly coupled, and decompression protection capsule is placed in the connection of cable connecting arrangement aperture internal screw thread, clip and slope limiter
Interference fit, big flat cable plug and clip be stuck, and limited screw connect with slope stop screw, feed liquor pressure retaining valve with
Cable connecting arrangement is threadedly coupled；It is using a kind of oil-submersible cable wet type connection method of novel submersible cable wet connection
It is realized by following steps:
A. decompression protection capsule is installed in cable connecting arrangement aperture, the insertion depth for adjusting limited screw guarantees slope
Big flat cable plug is inserted into clip one end by positioning of the limiter inside cable connecting arrangement；
B. in the case where relief valve is in close state, using the grease gun of included pressure gauge, by feed liquor pressure retaining valve to wet type cable
Pure oil liquid is injected in attachment device inner cavity, until observing that oil liquid is overflowed from cable connecting arrangement inner cavity；
C. be inserted into small flat cable plug, make connecting screw be in be not completely tightened state, using included pressure gauge grease gun after
Continuous oiling, makes cable connecting arrangement inner cavity bubble continue to be discharged, until observing that again bubble-free generates, tightens connecting screw；
D. continue to inject oil liquid, until oil gun pressure gauge registration reaches extraction well design work pressure, stop injection oil liquid, from feed liquor
Grease gun is removed on pressure retaining valve, completes cable connection.
Compared with the prior art the present invention has the advantages that
1) three phase isolated body is isolated using slope limiter structure, electric cable rotary can be effectively prevented, slip, played limit and make
With.
2) by injecting insulation oil liquid in oil-submersible cable wet connection inner cavity, tradition is substituted using wet type connection method
Connection method can be effectively isolated three cables, improve the insulation performance of oil-submersible cable wet connection.
3) by the way that internal pressure maintaining can be played the role of in oil-submersible cable wet connection inner cavity injection insulation oil liquid,
Can it is completely isolated oil, gas cut erosion, extend cable service life.
Detailed description of the invention: Fig. 1 is structure diagram of the invention.
In figure: the small flat cable plug of 1-, 2- connecting screw, 3- cable connecting arrangement, 4- relief valve, 5- decompression protection glue
Capsule, 6- clip, the slope 7- limiter, the big flat cable plug of 8-, 9- limited screw and 10- feed liquor pressure retaining valve.
Specific embodiment: below in conjunction with attached drawing, the invention will be further described: a kind of oil-submersible cable wet type connection side
Method and its device are by small flat cable plug 1, connecting screw 2, cable connecting arrangement 3, relief valve 4, decompression protection capsule 5, clip
6, slope limiter 7, big flat cable plug 8, limited screw 9 and feed liquor pressure retaining valve 10；Its medium and small flat cable plug 1 and cable connect
Connection device 3 is connected by connecting screw 2, and cable connecting arrangement 3 and relief valve 4 are threadedly coupled, and decompression protection capsule 5 is placed in electricity
The connection of 3 aperture internal screw thread of cable attachment device, clip 6 and slope limiter 7 are interference fitted, and big flat cable plug 8 and clip 6 are stuck in
Together, limited screw 9 and slope limiter 7 are threadedly coupled, and feed liquor pressure retaining valve 10 and cable connecting arrangement 3 are threadedly coupled；It utilizes
A kind of oil-submersible cable wet type connection method of novel submersible cable wet connection is through the following steps that realize:
A. decompression protection capsule 5 is installed in 3 aperture of cable connecting arrangement, the insertion depth for adjusting limited screw 9 guarantees tiltedly
Big flat cable plug 8 is inserted into 6 one end of clip by positioning of the slope limiter 7 inside cable connecting arrangement 3；
B. electric to wet type by feed liquor pressure retaining valve 10 using the grease gun of included pressure gauge in the case where relief valve 4 is in close state
