Abstract
The utility model provides a multifunctional well drilling boat for an ocean oil filed. The multifunctional well drilling boat comprises a hull part, a well drilling system and a pile leg system. The multifunctional well drilling boat for the ocean oil filed has better towing stability compared with a self-elevating platform and is more stable compared with the working environment of a traditional well drilling boat, the environment load borne by the well drilling system is more stable, the functions of offshore oil drilling, offshore lifting operation and life supporting can be achieved at the same time, and the boat is multipurpose and improves the use efficiency.
Description
Technical field
The utility model relates to boats and ships and field of ocean engineering, relates in particular to a kind of drill ship of water project exploration operation, more particularly, relates to a kind of marine oil field multifunctional drill ship.
Background technology
Development along with China's economic construction, increases day by day to energy demand.China has strengthened the exploitation to ocean, and the construction of these marine engineerings supports that to operation on the sea and life the demand of boats and ships/ocean platform is also increasing.
Carry out at present Offshore Operation and can use bottom-supported platform (being applicable to shallow water), jack-up unit (being applicable to shallow water), semisubmersible platform (being applicable to deep water), drill ship (being applicable to the super depth of water).Drill ship is floating vessel type offshore boring island, and it normally arranges drilling equipment on power ship or barge.Platform is by anchoring or dynamic positioning system location.When the depth of water is less than 200 meters, what the location of offshore drilling ship was conventional is the method for casting anchor, and so just can save the dynamic positioning system that expenditure of construction is huge.
Jack-up unit is to depth of water strong adaptability, and job stability is good, and development is very fast, accounts for half of portable drilling rig sum.But, when jack-up unit is shifted, because spud leg rises very highly, cause center of gravity high, stability is poor, and wind loading rating is poor.
utility model content
The purpose of this utility model be exactly in order to provide a kind of, be suitable in the probing of middle shallow water, towage stability is better, working environment is more stable, can carry out hoisting operation at sea, the marine oil field multifunctional drill ship that provides life to support for operation on the sea personnel.
The purpose of this utility model can realize by following scheme.
The marine oil field multifunctional drill ship that the utility model provides comprises: hull part, well system and spud leg system.
Spud leg system at least has four spud legs, etc. quantity be distributed in the both sides of hull, each spud leg bottom has a mat.
Hull partly has moon pool, and deck, moon pool top is furnished with well system.
Hull part can be provided with one or more in following equipment: lifting gear, helicopter, apron, life building, lifeboat.
The beneficial effects of the utility model are: marine oil field multifunctional drill ship of the present utility model has better towage stability than jack-up unit, working environment than traditional drill ship is more stable, the environmental load that well system bears is more stable, can realize offshore oil drilling, marine hoisting operation and life support function simultaneously, realize a ship multiplex, improved service efficiency.
Accompanying drawing explanation
Fig. 1 is the lateral view of the marine oil field multifunctional drill ship of the utility model-embodiment.
Fig. 2 is the top view of the marine oil field multifunctional drill ship of the utility model-embodiment.
In figure, 1. well system, 2. spud leg system, 3. hull part, 4. lifting gear, 5. helicopter, 6. apron, 7. life building, 8. lifeboat, 9. mat, 10. moon pool.
The specific embodiment
By reference to the accompanying drawings structural principle of the present utility model and operating principle are described in detail.Yet, should be appreciated that element, structure and the feature described in one embodiment also can be attached in other embodiment valuably in the situation that further not narrating.
As shown in Figure 1, the marine oil field multifunctional drill ship that the utility model provides comprises: hull part 3, well system 1 and spud leg system 2.The spud leg system 2 of the utility model-embodiment will be take six spud legs and the utility model will be described as example, yet this not should be appreciated that it is to restriction of the present utility model.
Spud leg system 2 at least has four spud legs, etc. quantity be distributed in the both sides of hull, each spud leg bottom has a mat 9.Drill-well operation requires very strict to the overall movement of hull, drilling riser pipe can not surpass four degree in the drift angle of vertical direction, and the overall movement performance of hull directly determines that can drill-well operation carry out smoothly.The utility model adopts the operating type of self lift type, can guarantee that hull can fix holding position, and the environmental load bearing during drilling system operation is more stable, has guaranteed carrying out smoothly of drill-well operation.
During jack-up unit displacement, because spud leg rises very highly, cause center of gravity high, stability is poor, and wind loading rating is poor.The utility model hull part 3 weight are larger, can effectively reduce hull center of gravity, for improving whole stability and wind loading rating, are highly profitable.
Hull part 3 has moon pool 10, and moon pool 10 decks, top are furnished with well system 1.Moon pool 10 is the cores of carrying out Offshore Operation, and the drilling pipe that well system 1 is used can directly probe into seabed from moon pool 10 and bore oil.
Hull part 3 can be provided with one or more in following equipment: lifting gear 4, helicopter 5, apron 6, life building 7, lifeboat 8, can guarantee that operation on the sea personnel can also obtain a comfortable safe living environment when completing production operation.Hull part 3 is provided with lifting gear 4, can complete smoothly the construction of marine major works.Spud leg system 2 can guarantee to provide sufficient stability and structural safety under outside moment loading that hull part 3 causes when lifting gear 4 band carries revolution.
With jack-up unit similarly, during work, the spud leg of marine oil field multifunctional drill ship the end, is supported on seabed, hull part 3 rises along spud leg, departs from water surface certain altitude, to avoid wave to bring impact to hull part 3.During drillng operation, after spud leg the end, the drilling pipe that well system 1 is used can directly probe into seabed from moon pool 10 and bore oil; During hoisting operation, after spud leg the end, lifting gear 4 can carry out hoisting operation.During displacement, hull part 3 declines and bubbles through the water column, and spud leg and mat 9 rise from seabed, and by the major part emersion water surface of spud leg, the water resistance when reducing to be shifted.
Although it should be pointed out that by above-described embodiment the utility model is described, yet the utility model can also have other numerous embodiments.Do not departing under the prerequisite of the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
