Description
Technical field
The utility model is related to the field of high-pressure well mouth T cable hangers more particularly to a kind of high-pressure well mouth T cable hangers are close
Seal bindiny mechanism.
Background technology
Oil well paraffinication is there are problems that in oilfield development process for a long time, oil field gas well, deep 7000m or so, down-hole pressure
120Mpa, 130 DEG C or so of temperature, 5 DEG C or so of wellhead temperature；Decline with gas production lifting and near-bottom temperature, apart from ground 3000m
Left and right, temperature are reduced to 60 DEG C or so, and wax starts to be precipitated；It may determine that, though wax is precipitated, but not solidifying pipe.When gaslift is to from the ground
When 2000-2500m, being calculated according to temperature gradient, temperature drops to 30 DEG C or so, and wax starts solidifying pipe, is deposited on tube inner wall,
Oil well is caused to narrow, oil well output reduces, and oil pipe can be also blocked when serious, oil well is caused to stop production.
It is general prevent the mode of wax deposition be addition some prevent the chemical reagent of wax deposition in oil well, but this mode
Mined oil can be caused to have to pass through the chemical reagent inside more processes removings, on the one hand process is caused to increase,
Input increases, and it is not pure enough on the other hand to will also result in the oil produced.
There are also using accompanying-heat cable come the oil inside oil well is carried out heating prevent wax deposition by the way of, hanger is
A kind of a kind of suspender combining accompanying-heat cable with oil extraction pipeline, hanger needs play suspension cable and switch blocks
Effect, it is more demanding to Hermetical connecting structure.
Invention content
The utility model is intended to research and develop hanger, and provides a kind of high-pressure well mouth T cable hangers sealed connection machine
Structure.
The utility model to achieve the above object, using following technical scheme：
A kind of high-pressure well mouth T cables hanger sealing connection mechanism, including hanger, the hanger inside are vertical through having
