Abstract
The invention relates to a rotating oil sucking pipe device used for deep-sea oil and gas well blowout. The device comprises a fast connector, an oil sucking pipe, a fixing barrel, a rotating block, a hydrate inhibitor injection pipe, a revulsant injection pipe, a sealing element and the like. When well blowout happens in the deep-sea oil and gas exploration and development operation, the rotating oil sucking pipe device is made to go into the seafloor. According to the specific position where seafloor leakage happens, the angle of the rotating oil sucking pipe is adjusted by an ROV, the rotating oil sucking pipe is inserted into the leakage point, and the leakage point is sealed and blocked through a sealing rubber core. When oil is sucked by the oil sucking pipe, revulsant and hydrate inhibitor enter the leakage point through the revulsant injection pipe and the hydrate inhibitor injection pipe respectively, oil receiving amount is improved, hydrate is prevented from being formed, and leaked oil and gas are guided to flow to a seal surface oil collecting ship through the oil sucking pipe.

Technical field
The present invention relates to deep-sea oil gas emergency set field, relate in particular to a kind of rotation oil suction pipe device for deep-sea oil gas blowout.
Background technology
Current deep-sea blowout oil accident emergency measure generally comprises ROV (ROV) and closes BOP (preventer), rescues the method such as slow well, reinforced concrete cover.ROV closes BOP ROV is transferred and closes original BOP to seabed, and original BOP lost efficacy sometimes, and ROV can not close BOP in time.Relief well method is consuming time long, can not control rapidly blowout and leak.Reinforced concrete cover structure is comparatively huge, steel consumption large and be difficult for installation, and it is higher that hydrate generates risk, can not control fast seabed and leak.China Petroleum forward South China Sea Deep Water strides forward, and exploitation deep-sea blowout jury rig is for ensureing that South Sea oil gas security development has important value.
The demand that deep-sea oil gas gas blowout accident proposes jury rig: (1) jury rig can be located and coordinate fast with leak, shortens the set-up time; (2), because seabed blowout pressure is higher, jury rig should have opposing high pressure ability; (3) emergency set can effectively suppress hydrate formation in deep water hyperbaric environment; (4) jury rig need meet the requirement such as lighting, miniaturization.
The invention provides a kind of simple in structure and can control fast the rotation oil suction pipe device of leakage.
Summary of the invention

The present invention is achieved through the following technical solutions:
A kind of rotation oil suction pipe device, is characterized in that: it comprises snap joint, fuel sucking pipe, stationary magazine creel, spill spin block, hydrate inhibitor ascending pipe, derivant ascending pipe, packing unit and potted component; Described spill spin block is arranged in stationary magazine creel circular cavity; Described fuel sucking pipe, derivant ascending pipe and hydrate inhibitor ascending pipe are welded on respectively stationary magazine creel and spill spin block one side.
Described stationary magazine creel arranges two pipelines, and pipeline welds mutually with fixing derivant ascending pipe and hydrate inhibitor ascending pipe.
Described stationary magazine creel is provided with circular cavity, block is set for limiting the spill spin block rotational angle coordinating with stationary magazine creel in cavity.
Described spill spin block is provided with dividing plate, described circular cavity is divided into the two halves cylindrical cavity not communicating.Dividing plate coordinates with described block the derivant and the hydrate inhibitor that inject is separated, and two injectants are separately injected separately.
Described spill spin block arranges seal groove, adopts seal with O ring with stationary magazine creel cooperation place.
Described two halves stationary magazine creel cooperation place, stationary magazine creel and dividing plate cooperation place all adopt sealing mat sealing.
When rotation fuel sucking pipe inserts leakage point, adopt described packing unit shutoff leakage point.
Described oil suction pipe device arranges deep floor in pipeline knee.
The present invention, owing to taking above technical scheme, has the following advantages: 1, the spill spin block of the present invention's design allows fuel sucking pipe to turn an angle, and can be used in multiple leakage scene.2, the present invention arranges block and dividing plate on stationary magazine creel and spill spin block, the derivant injecting and hydrate inhibitor can be separated by its cooperation, makes two injectants can not mix injection.3, the present invention designs snap joint, is convenient to be connected and transfer seabed fast with drilling rod, and leakage oil gas is guided to sea.The present invention is simple in structure, can Fast Installation and leakage oil gas is transported to sea oil-collecting boat.
