Description
Technical field
A kind of device for plugging when being leaked the present invention relates to ocean engineering field pipe-line, is particularly related to
And hydraulic pressure Quick leak stoppage apparatus and its blocking method under a kind of oil gas danger zone high-pressure process pipeline on-line production operating mode.
Background technology
In offshore oil and gas field exploitation, the widely used pipe of the oil gas medium with pressure such as Oil/gas Well Produced Liquid, qualified crude oil, associated gas
The mode in road is conveyed, due to pipeline manufacturing process itself defect and trandfer fluid when the factor such as dielectric corrosion, cause pipe
Various forms of leakages can occur unavoidably for road, thus trigger petroleum resources waste, seawater pollution, fire and blast, close a well in,
A series of problems, such as even jeopardizing personal safety in platform finite region and serious consequence.Pipe-line with pressure, especially
High-pressure process pipeline fast blockage under platform special operation condition is the important leverage of the defeated job safety operation of offshore oil tracheae, simultaneously
Because the cost produced by high-pressure no transmission leak stopping not only includes device for plugging and man power and material's expense, but also include leak stopping
The cost of oil gas is leaked in operation process, thus carrying out research to fast blockage technology using offshore platform limited resources will have
Significance.
The mode and approach of fast blockage with pressure have a variety of, and the fast blockage technology commonly used both at home and abroad at present can be concluded
For：1) steel band bundling technique, its product approval need not be prefabricated, and the live adaptability to changes to leakage region pipeline is stronger, but only leans on
Active force produced by steel band is tensed is difficult to the fluid conveying requirement for meeting high-pressure process pipeline；2) low pressure glues benefit technology, equally
The leak stopping of lower pressure operating mode is only applicable to, and existing various adhesive are difficult directly to carry out band pressure viscosity benefit, and need
A kind of guiding device is mended to realize with pressure viscosity, and execute-in-place is inconvenient；3) agent injecting type technology, such as epoxy resin, available for pressing
Power is more than 2MPa oil and gas leakage, but easily produces impact failure to the body of process pipe, and injecting equipment is complicated huge in itself,
Live material makes and operating procedure is complicated, is unfavorable for the fast blockage of offshore platform pipeline；4) welding technology is blocked up, in process pipe
Leakage point at first carry out early stage leak stopping by the way of stopper is played, then repaired using electric welding, although leak stopping can be realized,
But construction is inconvenient, plugging time is longer, and welding mode is not particularly suited for the stifled of offshore platform oil gas danger zone in itself
Leak operation.
In summary, the problem of having many in the platform specific occasion construction at sea of existing fast blockage technology, one
Part fast blockage technology is due to the limitation of the technology scope of application itself, is limited in oil gas danger zone and high-pressure process pipe
Popularization and application on road, another part fast blockage technology is due to that leak-stopping technique is complicated and speed is slow, does not reach fast blockage
Requirement.Relied on for this on the basis of existing practicable techniques, utilized from construction cost, platform limited resources, the activity duration and
The many-sides such as labor intensity, danger zone job requirements take in, and design and are applicable the quick stifled of high-pressure process pipeline leakage
Leakage device.
