Abstract
Provided is a single-leg simple platform at sea. The single-leg simple platform at sea comprises an upper module and a lower structure arranged below the upper module, wherein the lower structure is a single-leg stand column arranged at the center of the bottom of the upper module, a drill conductor is arranged on the single-leg stand column, the drill conductor is arranged inside the single-leg stand column or outside the single-leg stand column in parallel with the same. The single-leg simple platform at sea is simple in structure, simplifies a complex space frame structure, greatly reduces usage amount of steel, shortens construction period, saves construction cost under the condition that requirements of production operation at sea are satisfied, and meanwhile the modules of the simple platform are connected through the mode of assembling at sea so that the weight of every part is lowered, requirements of ships working at sea are lowered, and mounting 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 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 is 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 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 in a kind of sea comprises: 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, and waterproof casing is installed on the pillar with single leg.
Said pillar with single leg is by the steel pipe manufacturing.
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.

Main label declaration among the figure:
1. upper module, 2. substructure, 3. column, 4. piling bar, 5. supporting steel pipe, 6. waterproof casing, 7. cable protecting tube, 8. deck.
The specific embodiment
As shown in Figure 2; The utility model comprises: upper module 1, be installed in passive substructure 2 below the upper module 1, wherein, various productions and living facilities (figure does not show) can be installed on the deck 8 of upper module 1; Substructure 2 is for being installed in the pillar with single leg 3 of upper module 1 bottom centre; The load of upper module 1 is born by pillar with single leg 3, and this pillar with single leg 3 is by the steel pipe manufacturing, and waterproof casing 6 is installed on the pillar with single leg 3.Present embodiment: waterproof casing 6 is parallel to that pillar with single leg 3 is installed in the outside of pillar with single leg 3 or waterproof casing 6 is directly installed on the inside of pillar with single leg 3.During installation, respectively pillar with single leg 3 and waterproof casing 6 are squeezed into to setting the mud degree of depth by pile hammer.In the installation process, adopt welding manner to connect as one between upper module 1 and the pillar with single leg 3 at sea; Adopt the clamp connected mode to connect as one between pillar with single leg 3 and the waterproof casing 6, waterproof casing 6 is not born upper load.Adopt the clamp connected mode to connect as one between standpipe and cable protecting tube 7 and the pillar with single leg 3.Adopt the guiding connected mode to be connected between the top of waterproof casing 6 and the deck 8 on upper module 1, waterproof casing 6 only transmits the level environment load at this.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
