Abstract
The utility model discloses a kind of offshore oil production and set double V-shaped high pressure seal, it is characterized in that: this offshore oil production is set double V-shaped high pressure seal and comprised fuel-displaced well head pipe (1), sealing ring gland (2), upper V-seal steel ring (3), intermediate seal supporting seat (4), air vent (5), lower V-seal steel ring (6) and seal receptacle (7), and fuel-displaced well head pipe (1) installs seal receptacle (7).The utility model offshore oil production sets double V-shaped high pressure seal, at upper brill one radial direction through hole (5) of intermediate seal supporting seat (4).
Description
Technical field
The utility model provides a kind of sealing device, is specifically related to a kind of offshore oil production and sets double V-shaped high pressure seal.
Background technology
Chinese ocean petroleum and gas equipment enterprise has become manufacture strength important on extra large work market through development, occupies global jack-up unit 11%, drill ship 9%, the occupation rate of market of semisubmersible platform 37%, FPSO16%.The jack-up unit of domestic 61% and the semisubmersible platform of 43% are independently manufactured by China; The FPSO of 73% is independently manufactured by China.
Middle deep water bores completion and mainly equips dependence on import, does not possess the designed output of the deep water hydrocarbon field Development Engineering equipments such as large-scale FPSO, deep water lifting pipe laying vessel, deep water SPAR; Do not possess the production domesticization such as subsea production tree and underwater well head ability.
Because deepwater production tree correlation technique is subject to protection and the restriction of abroad a lot of patent and intellectual property, affect exploitation and the development in China's deep water hydrocarbon field.The research of China production tree is at the early-stage, also has very Da I Member gap at a distance of the offshore oil development power such as the U.S., Brazil, Norway, and domestic only have Baoji petroleum machinery, North China Rong Sheng, CNOOC research center and upper sea God to drive into have gone research.
Summary of the invention
The utility model provides a kind of offshore oil production to set double V-shaped high pressure seal, and utilize the utility model offshore oil production to set double V-shaped high pressure seal sealing wellhead, safe and reliable, sealing performance is high, long service life, and cost of production is low.
Technical solution of the present utility model is: this offshore oil production is set double V-shaped high pressure seal and comprised fuel-displaced well head pipe, sealing ring gland, upper V-seal steel ring, intermediate seal supporting seat, air vent, lower V-seal steel ring and seal receptacle, and seal receptacle installed by fuel-displaced well head pipe.
The utility model offshore oil production is set in double V-shaped high pressure seal, V-seal steel ring and intermediate seal supporting seat under seal receptacle is installed.
The utility model offshore oil production is set in double V-shaped high pressure seal, and intermediate seal supporting seat is installed V-seal steel ring and sealing ring gland.
The utility model offshore oil production is set in double V-shaped high pressure seal, intermediate seal supporting seat bores a radial direction through hole.
The utility model beneficial effect is: structure is simple, and safe and reliable, sealing performance is high, bears high-voltage performance strong, intermediate seal supporting seat bores a radial direction through hole, impel gases at high pressure equilibrium to be full of in upper and lower V-seal steel ring, reach isobaric object.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, fuel-displaced well head pipe 2, sealing ring gland 3, upper V-seal steel ring 4, intermediate seal supporting seat 5, air vent 6, lower V-seal steel ring 7, seal receptacle
Detailed description of the invention
As shown in Figure 1, this offshore oil production is set double V-shaped high pressure seal and is comprised fuel-displaced well head pipe 1, sealing ring gland 2, upper V-seal steel ring 3, intermediate seal supporting seat 4, air vent 5, lower V-seal steel ring 6 and seal receptacle 7, and seal receptacle 7 installed by fuel-displaced well head pipe 1.
The utility model offshore oil production is set in double V-shaped high pressure seal, V-seal steel ring 6 and intermediate seal supporting seat 4 under seal receptacle 7 is installed.
The utility model offshore oil production is set in double V-shaped high pressure seal, and intermediate seal supporting seat 4 is installed V-seal steel ring 3 and sealing ring gland 2.
The utility model offshore oil production is set in double V-shaped high pressure seal, intermediate seal supporting seat 4 bores a radial direction through hole 5.
The utility model beneficial effect is: structure is simple, and safe and reliable, sealing performance is high, bears high-voltage performance strong, intermediate seal supporting seat bores a radial direction through hole, impel gases at high pressure equilibrium to be full of in upper and lower V-seal steel ring, reach isobaric object.
