Abstract
The present invention relates to a kind of four spud legs pair boring tower self-elevating drilling platform.Including main platform body（1）, spud leg（Containing shoe）（2）, wedge bracket（3）, rig floor（4）, drillingrig base（5）And boring tower（7）.Main platform body（1）Zone line is designed with moon pool structure, and moon pool both sides are provided with slide rail（6）, drillingrig base（5）Can be along being fixed on main platform body（1）On slide rail（6）Mobile.Spud leg（Containing shoe）（2）By wedge bracket（3）With main platform body（1）Connect.It is installed on wedge bracket（3）Interior elevating mechanism and spud leg（2）On tooth bar engagement.It is installed on wedge bracket（3）Interior retaining mechanism and spud leg（2）On tooth bar engagement.Rig floor（4）It is arranged in drillingrig base（5）On, can be along being fixed on drillingrig base（5）On slide rail（6）Mobile.Boring tower（7）It is fixed on rig floor（4）On.Improve the bearing capacity of platform, increase the deck loads of platform, adapt to deeper sea situation.
Description
Technical field
This invention belongs to modern marine engineering structure master-plan class.
Background technology
Existing self-elevating drilling platform is typically designed to three spud leg formulas, and spud leg bottom is provided with boot-shaped mat, can " stand " in seabed.The tooth bar on spud leg and installation lifting locking device in structure is relied on to realize lifting and the fixation of platform.Drilling rig structure is arranged on the cantilever beam that can slide, and all around moves, with respect to main platform body, the purpose to realize beating collecting well group by cantilever beam or rig floor.
Limited by platform deadweight and structural strength, it is very big that the physical dimension of cantilever beam can not possibly design, and the displacement of such drilling rig structure is affected.Due to can produce very big bending moment when cantilever beam is overhanging, the weight of drilling rig structure just receives restriction, and efficiently double boring tower designs cannot be realized.
Content of the invention
It is an object of the invention to provide a kind of self-elevating drilling platform of four spud legs pair boring tower.Solve the problems, such as that existing jack-up unit drilling rig structure moving range is little and cannot realize boring two mouthfuls of wells simultaneously.Increase the moving range of drilling rig structure, the stake of platform one secondary, greater number of oil well can be bored.And realize double boring tower designs, two mouthfuls of wells can be bored simultaneously, improve the economic benefit of the drilling platforms of jack up.
The present invention is novel in design, safe and reliable.Because present invention eliminates cantilever beam, rig floor directly all around moves above moon pool, alleviates the construction weight carrying drilling rig structure, thus increasing Platform Deck load, improves safety and economic benefit.The design of double boring towers makes to bore two mouthfuls of wells simultaneously and becomes a reality, the economic benefit improving drilling efficiency, lifting drilling platforms further at double.The design of four spud legs makes the bearing capacity of platform higher, increases the deck loads of platform and adapts to deeper sea situation.
Brief description
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of the present invention, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the B-B profile of Fig. 1.
Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of four spud legs pair boring tower self-elevating drilling platform mainly includes main platform body（1）, spud leg（Containing shoe）（2）, wedge bracket（3）, rig floor（4）, drillingrig base（5）And boring tower（7）.Main platform body（1）Zone line is designed with moon pool structure, and moon pool both sides are provided with slide rail（6）, drillingrig base（5）Can be along being fixed on main platform body（1）On slide rail（6）Mobile.Spud leg（Containing shoe）（2）By wedge bracket（3）With main platform body（1）Connect.It is installed on wedge bracket（3）Interior elevating mechanism and spud leg（2）On tooth bar engagement, it is possible to achieve the function of lifting.It is installed on wedge bracket（3）Interior retaining mechanism and spud leg（2）On tooth bar engagement, it is possible to achieve the function of fixed platform main body.Rig floor（4）It is arranged in drillingrig base（5）On, can be along being fixed on drillingrig base（5）On slide rail（6）Mobile.Boring tower（7）It is fixed on rig floor（4）On.
This self-elevating drilling platform is disposed with two sets of drilling equipments, it is possible to achieve bore the needs of two mouthfuls of oil wells simultaneously.The setting of moon pool can make drilling tool by reaching in the middle part of platform under sea, executes drillng operation.The arrangement of drillingrig base and slide rail is realized drilling rig structure and is all around moved with respect to main platform body, realizes pitching pile of platform, can beat the purpose of collecting well group.Rig floor and boring tower have the ability carrying two sets of drilling rig structure.
This self-elevating drilling platform is characterised by：1st, have from liter function；2nd, it is disposed with four spud legs；3rd, it is provided with two sets of drilling rig structure, two mouthfuls of oil wells can be bored simultaneously；4th, it is designed with moon pool；5th, rig floor can move left and right with respect to main platform body priority.
It is understandable that, above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and not first with the technical scheme described by the embodiment of the present invention, it will be understood by those within the art that, still the present invention can be modified or equivalent, reach identical technique effect；As long as meeting invention needs, all within protection scope of the present invention.
