Abstract
The utility model discloses a deep-water drilling device, and relates to an underwater drilling device. The deep-water drilling device is composed of a floating barrel and a drilling platform which is matched with the floating barrel, wherein the drilling platform is a semi-submersible type drilling platform. The deep-water drilling device meets the operation requirements of sea areas with concentration about 1500m, and accordingly the device can be used for operation of the sea areas with water depth smaller than 1500m.
Description
Technical field
The utility model relates to a kind of underwater drilling device.
Background technology
Deepwater drilling is the emerging market of international ocean oil circle, and it is containing higher technology content.Up to now, can be engaged in the world the country of creeping at the deep-sea, ocean and only have 4-5, mainly contain the states such as the U.S., Britain, Norway, Brazil.Deep sea drilling not only needs superb marine drilling technology, also needs a huge sum of money support.When well depth was identical, it is higher 100 times than land drillng operation total cost that deep water creeps into the operation total cost, higher 10 times than shallow sea, ocean operation total cost.
In the world, usually will be called over the marine site of the 500m depth of water deep-sea or deep water; And the marine site that surpasses the 1500m depth of water is called super deep-sea or super deep water.The deep sea drilling ability of marine oil field has represented the offshore oil work capacity of a country or company, has also included most of advanced technologies and the operation technique of offshore petroleum drilling.
Summary of the invention
The utility model aims to provide a kind of deepwater drilling device of 1500m left and right that depth of implements is brought up to by 457m.
Deepwater drilling device described in the utility model reaches by floating drum the offshore boring island that is complementary with floating drum and forms.
Preferably, described offshore boring island is semisubmersible drilling platform.
More preferably, in described offshore boring island under by upper interconnective seabed coupling, tie back stem, preventer and the marine riser of being provided with successively, upper and lower preventer and the tie back stem of connecting respectively of floating drum wherein.
Further preferably, described floating drum is connected with preventer by foam floating body.
Perhaps further preferably, also be provided with control device on described offshore boring island, it is connected with floating drum by control umbilical.
Perhaps further preferably, also be provided with air compressor on described offshore boring island.
Still more preferably, described float-level height is 10m, and diameter is 20m, and gross mass is 405 tons.
Device described in the utility model has satisfied the marine site job requirements of 1500m left and right concentration, thereby can be used in the marine site operation of the depth of water less than 1500m.
Description of drawings
Fig. 1 is the structural representation of embodiment one.
The specific embodiment
Embodiment one.
Deepwater drilling device described in the utility model reaches by floating drum 8 semisubmersible drilling platform that is complementary with floating drum 8 and forms.Floating drum 8 is highly 10m, and diameter is 20m, and gross mass is 405 tons.
In described offshore boring island under by upper interconnective seabed coupling 1, tie back stem 2, preventer 3 and the marine riser 4 of being provided with successively, wherein floating drum 8 tops are connected with preventer 3 by foam floating body 7, the bottom directly is connected with tie back stem 2.
Also be provided with in addition control device 6 on offshore boring island, it is connected with floating drum 8 by control umbilical.And also be provided with air compressor 5 on offshore boring island.
Deepwater drilling device operation process described in the utility model is.
Semisubmersible drilling platform and large-scale tugboat are arrived the operation marine site.
Offshore boring island is completed well and is crept into, and setting of casing, well cementation.
Below offshore boring island, apart from 250 meters marine location of carrying out floating drum 8 of the water surface.
Offshore boring island is lowered to the subsea wellheads coupling, by the centre bore of floating drum 8, and carries out tie back stem 2 tieback operations.
Carry out preventer 3 installs on floating drum 8 tops.
Be lowered to marine riser 4 from the offshore boring island bottom, connect with preventer 3.
The performance test of floating drum 8 etc. of being correlated with comprises being lowered to drilling rod, carries out conventional drilling.
After test is completed, with program opposite to said process, carry out the recovery of floating drum 8, and " abandoned well " operation.
