Description
Technical field
The present invention relates to the sealing of boll-weevil hanger cable penetration device hole, be specifically related to a kind of boll-weevil hanger cable penetration device mesoporous metal sealing device.
Background technology
At present, the known cable penetration device of boll-weevil hanger is the most widely replaced the rubber seal that is sealed between plug and boll-weevil hanger; Because well head operation is flowing well in earlier stage, well head pressure is higher, and corrosivity is strong, and what sometimes in well head, exploit is highly corrosive gas, there is certain safety issue in well head, therefore needs design to meet the boll-weevil hanger cable penetration device mesoporous metal sealing device of this operating mode.
Summary of the invention
The object of the invention is to: a kind of boll-weevil hanger cable penetration device hole sealing device is provided, and sealing apparatus structure is simple, install easily, safe and reliable, can ensure again sealing long-term between boll-weevil hanger and cable penetration device passage.
The scheme of technical solution problem of the present invention is: sealing device comprises plug No. one, an O type circle, a metal o-ring, a pad, No. two metal o-rings, No. two pads, No. two O type circles, No. two plugs, No. three O type circles and No. three plugs, No. one metal o-ring is arranged on the conical surface of a plug, No. one pad is arranged on the upper surface of a metal o-ring, No. two plug is connected with the male thread of a plug upper end by the box thread on body, O type circle is installed on the outer wall of a plug No. one, No. three plug is connected with the male thread of No. two plug upper ends by the box thread on body, No. two metal o-ring is arranged on the conical surface of No. three plugs, No. two pad is arranged on the upper surface of No. two metal o-rings, O type circle is installed on the outer wall of No. two plugs No. two, O type circle is installed on the outer wall of No. three plugs No. three, entirety forms boll-weevil hanger cable penetration device hole sealing device.
When installation, on the outer wall of a plug, No. two plugs and No. three plugs, install respectively an O type circle, No. two O type circles, No. three O type circles; Cable penetration device access opening by plug tubing hanger packs into from top to bottom, and is screwed to clockwise the end, and a metal o-ring and pad Anshun order are packed in tubing hanger penetration device access opening; By in No. two plug load holes and tighten, excite the sealing between plug and tubing hanger; Tubing hanger is packed in well head, install production tree crossover flange, No. two metal o-rings and No. two pad Anshun orders are packed in production tree crossover flange cable penetration device access opening; By in No. three plug load holes and tighten, excite the sealing between plug and production tree crossover flange.
The present invention has the following advantages: 1. the sealing between metal sealing device and tubing hanger, production tree crossover flange is taking metal sealing as primary seal, and taking rubber seal as auxiliary seal, metal o-ring decay resistance is strong, has increased the security reliability of sealing; 2. between metal o-ring and plug, coordinate tapering less, design is conducive to the sealing that excites of metal o-ring compared with Small Taper, is more conducive to install; 3. metal sealing device adopts segmentation structure, forms sealing for boll-weevil hanger and production tree crossover flange, and this structure is convenient to installation and removal.
