Abstract
The utility model relates to a one-legged raking pile simple platform at sea, which comprises an upper part module and a lower part structure arranged under the upper part module, wherein the lower part structure is a one-legged upright post mounted in the center of the bottom of the upper part module; a plurality of inclined steel piles are arranged on the periphery of the one-legged upright post; a drill conductor is mounted at the lower part of the upper part module; and thus the one-legged raking pile simple platform structure is formed through the connection. The one-legged raking pile simple platform at sea is simple in structure, simplifies a complex space frame structure under the premise of meeting production operation requirements at sea, reduces the use amount of steel products substantially, shortens the construction working periods, and saves the construction cost; and meanwhile, as components of the simple platform are connected through an assembly method at sea, the weight of each part is reduced; the requirements for the offshore construction ships are further reduced, and the installation cost is saved.
Description
Technical field
The utility model relates to production platform, relates in particular to a kind of marine solely simple and easy platform of leg taper pile that is suitable for small field and marginal field exploitation in the sea.Belong to offshore oil engineering field.
Background technology
Often to use the offshore oil exploitation platform in the petroleum development engineering at sea.
As shown in Figure 1; Existing offshore production platform comprises: upper module 1, be installed in passive substructure 2---jacket below the upper module 1, wherein, various productions and living facilities (figure does not show) can be installed on the upper module 1; Substructure 2---jacket mainly comprises: four columniform steel pipe leg posts 3; The inside of every steel pipe post 3 all is with piling bar 4, and the effect of piling bar 4 is to squeeze into the seabed with fixing whole flat, is provided with several supporting steel pipes 5 between four steel pipe posts 3; These supporting steel pipes 5 and four steel pipe post 3 a common firm substructure 2---truss-like jackets of forming are in order to support upper module 1.In the framework of jacket, some waterproof casings 6 can be installed as required.When specifically offshore platform being installed, generally be divided into for two steps, at first, jacket transported to the scene, in four steel pipe posts 3 of jacket, piling bar 4 is inserted and squeeze into the seabed, after fixing jacket, again upper module 1 is installed on the jacket.
Above-mentioned offshore production platform, its structure is more stable, is fit to very much be operated in reach under the complicated marine environment condition in the relatively large oil-gas field development application.But, because its weight of offshore platform of this form of structure is heavier relatively, install and more complicated, therefore, its cost is also higher relatively.And in some seas in the exploitation of small field and marginal field, because the required well head number of its oil gas field is less, production facility is also simple relatively, and the personnel of need not garrison operation; And its weight of equipment also is far smaller than the production platform of above-mentioned routine, and is under this condition, if still use the production platform structure of above-mentioned routine, very non-remunerative beyond doubt.Therefore, in the exploitation of middle at sea small field and marginal field, only need to use some simple and easy platforms, can carry out oil producing operation.The utility model promptly designs under above-mentioned situation.
The utility model content
The main purpose of the utility model is to overcome the above-mentioned shortcoming that prior art exists; And providing the only leg taper pile in a kind of sea simple and easy platform, it is simple in structure, can be under the prerequisite that satisfies the offshore production job requirements; Simplified numerous and diverse space frame structure; Reduce the use amount of steel significantly, shortened construction duration, practiced thrift construction cost; Simultaneously,, therefore, alleviated each several part weight, also just reduced requirement, practiced thrift installation cost again the offshore construction boats and ships because each assembly of simple and easy platform is to connect through the mode that assemble at the sea.
The purpose of the utility model is realized by following technical scheme:
The simple and easy platform of the only leg taper pile in a kind of sea; Comprise: upper module, be installed in the substructure below the upper module; It is characterized in that: substructure is a pillar with single leg that is installed in upper module bottom centre; The periphery of this pillar with single leg is provided with the piling bar of several inclinations, and the bottom of this upper module is equipped with waterproof casing, through the above-mentioned simple and easy platform structure of an only leg taper pile that connects and composes.
Said pillar with single leg is by the steel pipe manufacturing.
Be to adopt the piling bar guidance set to be linked to be an integral body between the piling bar of said pillar with single leg and several inclinations, and the piling bar of several inclinations is positioned at orthogonal two planes.
The piling bar of said inclination is welded to connect into an integral body at the top by the imperial crown plate with the piling bar guidance set.
Said waterproof casing is installed in the inside of pillar with single leg or is parallel to the outside that pillar with single leg is installed on pillar with single leg.
Adopt the guiding connected mode to be connected between the top of said waterproof casing and the deck on upper module, employing clamp connected mode connects as one between waterproof casing and the pillar with single leg.
The beneficial effect of the utility model: the utility model is owing to adopt technique scheme; It is simple in structure; Can under the prerequisite that satisfies the offshore production job requirements, simplify numerous and diverse space frame structure, reduce the use amount of steel significantly; Shorten construction duration, practiced thrift construction cost; Simultaneously,, therefore, alleviated each several part weight, also just reduced requirement, practiced thrift installation cost again the offshore construction boats and ships because each assembly of simple and easy platform is to connect through the mode that assemble at the sea.
