Abstract
The utility model discloses a light duty offshore platform including a deck chunk, a waterproof casing and a spud leg. The spud leg is provided with two main leg poles and an underwater ancillary supporting spud. An inclined supporting element is respectively arranged between the underwater ancillary supporting spud and the two main leg poles, a layer of horizontal supporting structure is arranged in the two inclined supporting elements, and a horizontal supporting element and an inclined supporting pole are arranged between each inclined supporting element and the spud leg connected with the inclined supporting element. Though the utility model is only provided with two main leg poles, with the installment of underwater ancillary supporting spud, the stress of the utility model is reasonable, the structure is stable, the integral strength remains unchanged, and the utility model satisfies the code requirement. The utility model is a light duty offshore platform. The utility model has the following advantages: a great amount of steel are saved, the cost of investment is reduced, and the utility model is very suitable for the development of small oil field and marginal oil field.
Description
Technical field
The utility model relates to offshore platform, particularly about a kind of version of light offshore platform.
Background technology
Marine petroleum development occupies critical role in industrial economy.Because environment is abominable, the marine oil engineering is often invested greatly, the cost height, and operation has particularity.The reserves small scale of small oil field, marginal oil field, recovery efficiency is low, if exploitation according to a conventional method, then cost of investment is excessive, is difficult to obtain economic benefit.In the today of being becoming tight petroleum-based energy day, how to adopt new mode, up-to-date technology, develop resources such as small oil field, marginal oil field scientifically and rationally, be crucial problem.
The innovation and creation content
The utility model is the exploitation at small oil field, marginal oil field, and a kind of simple in structure, lower light-duty offshore oil platform of investment is provided.
For achieving the above object, the utility model is taked following technical scheme: a kind of light offshore platform, and it comprises deck chunk, drill conductor and spud leg, described spud leg is two main leg posts and a supplemental support stake under water.
In practical operation, respectively be provided with a diagonal ligament spare and a bottom surface horizontal support structure triangular in shape between stake of described supplemental support under water and the two main leg posts respectively; Be provided with the quadrangle horizontal support structure between described two main leg posts and the two diagonal ligament spares, and described two main leg posts and flat-bed junction are provided with the umbrella bracing or strutting arrangement.
In order to make structure of the present utility model more stable, between the described two main leg posts at least one horizontal brace rod spare is set, and the horizontal brace rod of described top layer is arranged on the sea level below 5 meters, and also is provided with oblique pipe link between each horizontal brace rod.
In actual applications, drill conductor operated by rotary motion 2-4 root.
Through combinations thereof, the pentahedron framed structure of a solid is formed in described two main leg posts and a supplemental support stake under water, and one side is a quadrangle, and the four sides is a triangle in addition.
The utility model mainly has the following advantages owing to take above design:
1, the utility model two main leg posts only on the structure have reduced by 2 leg posts than four traditional leg platforms, are a kind of real light-duty offshore platforms, saved great deal of steel, simplify offshore construction, reduced cost of investment, very be suitable for the exploitation of small oil field, marginal oil field.
2, supplemental support stake under water with make that platform structure is stable more, force-bearing situation is reasonable being connected of two main leg posts; Though be the jacket of two main leg stakes, its bulk strength still can be resisted 50 years one extreme stormy waves conditions of meeting.
3, the top layer horizontal bars between the two main leg posts is positioned at the following 5m of horizontal surface, can reduce wave power effectively, and whole structural stability strengthens.
4, the flat-bed rod member is formed the pentahedron framed structure of a solid, and one side is a quadrangle, and the four sides is a triangle in addition, and except that the bottom surface was a big triangle, the four sides was divided into 3-4 triangle again in addition." triangle stability " is the most basic mechanics principle, and the utility model has made full use of this principle.
5, two main leg post support deck are the most basic balanced structures, and are stressed reasonable, good stability.Four once the rod member arranged of umbrella make the deck always scheme to arrange convenient, Load Transfer is clear and definite.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, light offshore platform of the present utility model comprises deck chunk 1, two drill conductors 2 and spud legs, and spud leg mainly includes two main leg posts 3 and a supplemental support stake under water 4; Between the two main leg posts 3 three horizontal brace rod spares 5 are set, are respectively horizontal brace rod spare 51, middle horizontal brace rod spare 52 and following horizontal brace rod spare 53.Deck chunk 1 is arranged on the top of two main leg posts 3,4 pairs two main leg posts 3 of supplemental support stake under water play the effect of supplemental support, respectively be provided with a diagonal ligament spare 6 and a bottom surface horizontal support member 7 respectively between supplemental support stake under water 4 and the two main leg posts 3, bottom surface horizontal support member 7 and following horizontal brace rod spare 53 are on same horizontal surface, so form a bottom surface horizontal support structure triangular in shape.In addition, between the two diagonal ligament spares 6 horizontal support member 61 is set, between the corresponding bonded assembly master of the diagonal ligament spare 6 leg post 3 horizontal support member 61 is set all also with it, horizontal support member 61 and middle horizontal brace rod spare 52 are on same horizontal surface, be the quadrangle horizontal support structure so form one, and, between the diagonal ligament spare 6 connected main leg posts 3 an oblique pipe link 62 is set also.In the present embodiment, last horizontal brace rod spare 51 is arranged on the sea level below 5 meters, can reduce the impact of wave force to it effectively like this; Two main leg posts 3 are provided with umbrella and support 31 in the junction with platform 1, umbrella bracing or strutting arrangement 31 is the support deck load well; And, also be provided with oblique attaching parts 8 between each horizontal brace rod spare 5 in order to make structure of the present utility model more stable.
In the present embodiment, the pentahedron framed structure of a solid is formed in main leg post 3 and supplemental support stake under water 4, main leg post 3 is a quadrangle with the one side that horizontal brace rod spare 5 is formed, two diagonal ligament spares 6 are triangle with the one side that last horizontal brace rod spare 51 is formed, two diagonal ligament spares, 6 connected main leg posts 3 and bottom surface horizontal support member 7 are respectively formed a gore again, and bottom surface horizontal support structure triangular in shape is a gore.In sum, the pentahedron framed structure simultaneously is a quadrangle, and the four sides is a triangle in addition, and except that the bottom surface was a big triangle, the four sides was divided into 3-4 triangle again in addition." triangle stability " is the most basic mechanics principle, and the utility model has just made full use of this principle, so the utility model is stressed rationally, good stability.
