Abstract
The invention belongs to the field of construction equipment for offshore drilling operation and discloses a drilling ship which comprises floating ship bodies, windlasses, propellers, uprights, connecting cross beams, a cockpit, a helicopter platform, a drilling tower, tower cranes, a machine platform framework, a drilling base and a drilling platform. Each floating ship body is of a hollow closed-type ship body structure, four propellers are arranged under each floating ship body, two uprights are welded on each floating ship body and connected through one connecting cross beam, the drilling base is built at the tops of the uprights, four sets of windlasses are arranged on the left side and the right side of the drilling base, the tower cranes are arranged the left side and the right side of the drilling base, the cockpit is built on the drilling base, the helicopter platform is arranged at the top of the cockpit and arranged overhead the drilling base through the machine platform framework, the drilling platform is fixed on a wellhead in the middle of the drilling base, and the drilling tower is mounted on the drilling platform. By the drilling ship, the problems of huge difficulty and extremely high cost in building a base-type platform at an abyssal area and proneness to causing huge loss due to the fact that low-grade ore is mined after the platform is built are solved.
Description
Technical field
The present invention relates to drilling ship, belong to the preparation of construction field of Offshore Operation.
Background technology
At present China's oil problem in short supply has become increasingly conspicuous has become the state of second largest energy resource consumption in the world, China's oil is consumed external interdependency and has been reached 49%, and the Growth of Consumption impetus is still continuing, account for 1/3rd of China's oil total resources according to statistics China of National Energy Board south sea petroleum geology storage capacity, and substantially belong to abyssal area, the technology that country does not have moulding in abyssal area, the South Sea is at present to the basic base type platform that uses of its exploitation, jack-up platform is exploited offshore oil, extremely difficult owing to building base type platform or jack-up platform in abyssal area, investment cost is tens times of shoal water zone, and blindly build base type platform in abyssal area and exploit and very easily adopt lean ore and cause great loss.The problem of encountering in order to solve current China's mining depth sea area oil, need to develop a energy and be applicable to abyssal area applicable neritic area, relatively cheap, the safe and reliable novel offshore oil exploitation equipment of cost again.
Summary of the invention
The object of this invention is to provide drilling ship.
The problem to be solved in the present invention be build in abyssal area that base type platform is extremely difficult and expense is high, built platform after exploitation easily cause the problem of great loss to lean ore.
For realizing object of the present invention, the technical solution used in the present invention is:
Drilling ship, comprise pontoon body, windlass, propelling unit, column, connecting cross beam, driving compartment, helicopter platform, drilling well pylon, tower crane, board skeleton, drilling well pedestal and drilling platform, described pontoon body is the closed hull steel structure of hollow, pontoon body has two, under each pontoon body, there are four propelling units, propelling unit is arranged on each two of stem and ship stern, on each pontoon body, be welded with two root posts, between column, be connected and fixed by connecting cross beam, column top has drilling well pedestal, the drilling well pedestal left and right sides is provided with 4 groups of windlass altogether, the drilling well pedestal left and right sides is also provided with tower crane and facilitates carrying and the transfer of mechanical equipment, driving compartment is built on drilling well pedestal, driving compartment top is provided with helicopter platform, helicopter platform is maked somebody a mere figurehead on drilling well pedestal by board skeleton, board skeleton is formed by shaped steel assembly welding, drilling well pedestal is provided with multiple well heads, in the middle of drilling well pedestal, on well head, be fixed with drilling platform, drilling well pylon is housed on drilling platform, it is firm that drilling well pylon is connected into grid structure safety by steel welding.
Propelling unit is 360 ° of full circle swinging types, and propelling unit is streamlined reefer housing in addition; Windlass is to drag three units; Drilling well pylon maximum height is 30 meters.
Advantage of the present invention is: adopt pontoon body to solve as the carrier of drilling ship difficulty and trouble that exploitation offshore oil need be built base type platform completely, pontoon body is can be shifted and recycle the waste that can not cause up-front investment completely after the drilling ship of carrier is once built, drilling well pedestal is fixed the demand that has not only met marine drilling and has been met simultaneously the demand of structural strength by column and connecting cross beam, on drilling well pedestal, adopt 4 group one to drag the windlass of three units to locate completely pontoon body, on drilling ship, be also provided with helicopter platform and facilitate crew's investigation and on and off duty.
Accompanying drawing explanation
Fig. 1 is drilling ship integral structure figure of the present invention;
Fig. 2 is drilling ship local structural graph of the present invention;
In figure: 1, pontoon body 2, windlass 3, propelling unit 4, column 5, connecting cross beam 6, driving compartment 7, helicopter platform 8, drilling well pylon 9, tower crane 10, board skeleton 11, drilling well pedestal 12 drilling platform.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Drilling ship of the present invention, comprise pontoon body 1, windlass 2, propelling unit 3, column 4, connecting cross beam 5, driving compartment 6, helicopter platform 7, drilling well pylon 8, tower crane 9, board skeleton 10, drilling well pedestal 11 and drilling platform 12, described pontoon body 1 is the closed hull steel structure of hollow, pontoon body 1 has two, adopt pontoon body 1 to solve as the carrier of drilling ship difficulty and trouble that exploitation offshore oil need be built base type platform completely, the drilling ship that pontoon body 1 is carrier can be shifted and recycle the waste that can not cause up-front investment completely after once building, each pontoon body has for 1 time the propelling unit 3 of 360 ° of full circle swinging types of four tyre streamlined reefer housings that power resources are provided, propelling unit 3 is arranged on each two of stem and ship stern, on each pontoon body 1, be welded with two root posts 4, between column 4, be connected and fixed by connecting cross beam 5, column 4 tops have drilling well pedestal 11, drilling well pedestal 11 left and right sides are provided with altogether 4 group one and drag the windlass 2 of three units to locate completely pontoon body 1, drilling well pedestal 11 left and right sides are also provided with tower crane 9 and facilitate carrying and the transfer of mechanical equipment, driving compartment 6 is built on drilling well pedestal 11, driving compartment 6 tops are provided with helicopter platform 7 and facilitate crew's investigation and on and off duty, helicopter platform 7 is maked somebody a mere figurehead on drilling well pedestal 11 by board skeleton 10, board skeleton 10 is formed by shaped steel assembly welding, drilling well pedestal 11 is provided with multiple well heads, in the middle of drilling well pedestal 11, on well heads, is fixed with drilling platform 12, and drilling well pylon 8 is housed on drilling platform 12, and drilling well pylon 8 maximum heights are 30 meters, and to be connected into grid structure safety by steel welding firm.
