Description
Technical field
The present invention relates to the field of high-pressure well mouth T cable hangers, more particularly to a kind of sealing of high-pressure well mouth T cables hanger to connect
Connection mechanism.
Background technology
Oil well paraffinication is oil field gas well the problem of existing for a long time in oilfield development process, 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 separate out；It may determine that, though wax separates out, but not solidifying pipe.When gaslift is to from the ground
During 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 and causes oil well to stop production.
The general mode for preventing wax deposition prevents the chemical reagent of wax deposition in oil well to add some, but this mode
Mined oil can be caused to have to pass through the chemical reagent inside more processes removings, on the one hand cause process to increase,
Input increase, it is not pure enough on the other hand to will also result in the oil produced.
Now also have 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 for combining accompanying-heat cable with oil extraction pipeline, hanger needs to play suspension cable and switch blocks
Effect, it is more demanding to Hermetical connecting structure.
The content of the invention
It is contemplated that being researched and developed to hanger, and provide a kind of high-pressure well mouth T cables hanger sealing connection mechanism.
The present invention 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
Oil/cable passage, upper end is equipped with slip spider in the oil/cable passage, in the slip spider from bottom to top according to
Secondary to be provided with slips, slips pressing sleeve, high temperature resistant packing and clamp nut, the hanger is in the side at slip spider bottom both ends
Wall is equipped with slip spider jackscrew, and slip spider upper end side is equipped with positioning fixed pin, and the positioning fixed pin is located at oil/line
On the inner wall of cable passage, part of the hanger below the slip spider is high pressure main valve, the slip spider of the hanger
Metallic packing ring is equipped between bottom and high pressure main valve, the metallic packing ring bottom side is equipped with and holds out against jackscrew.
T cables extraction sealing threeway is connected with the top of the hanger and bottom is connected with fixed installation flange, the T cables are drawn close
Inside back cover is equipped with oil channel in leading to, and the oil channel side that the T cables draw sealing threeway is equipped with cable passage, and the oil leads to
Road, cable passage are connected with oil/cable passage in hanger.
The slips is bi-directional slip.
The beneficial effects of the invention are as follows：Hanger high temperature resistant, the leakproofness of the present invention is good, and connection relation is simple, can rise
The effect blocked to switch.
