Abstract
The utility model relates to a simple platform with single leg and three piles suitable for the development of small and medium-sized oil and gas fields in the sea and marginal oil field, which comprises a upper module and a substructure. A single leg column is arranged on the center of the substructure and three sleeve components is arranged on the external. A plurality of steel pipes are provided between the single leg column and three sleeve components to support as a whole. Plural upper struts are proviede between the single leg column and the upper strut. The sleeve component comprises a steel pile and an external steel pipe sleeve. The steel pile and the steel pipe sleeve are fixed by cement. Three sleeve components are located on the trisection point region of the concentric circle with the single leg column as the circle center(at +/-10 degrees change); The single leg column is manufactured by steel and equipped with anti-ice cone on its external (only for the sea ice, other waters are not installed), and equipped with septal water casing, pump protecting tube, riser, cables and so on. The new technology significantly reduces steel consumption and decreases manufacturing costs under the presence of meeting the product requirements.
Description
Technical field
The utility model relates to a kind of offshore oil exploitation platform, relates in particular to a kind of platform with only leg three pileworks that is suitable for small field and marginal field exploitation in the sea.
Background technology
Often will use the offshore oil exploitation platform in the petroleum development engineering at sea, its traditional structure is such:
With reference to Fig. 1, the offshore oil exploitation platform is divided into two large divisions up and down, and top is upper module 1, and various productions and living facilities (not shown) can be installed on it, and the bottom is passive jacket 2.Jacket mainly comprises four columniform steel pipe leg posts 3, the inside of every steel pipe leg post 3 all is with piling bar 4, the effect of piling bar 4 is to squeeze into the seabed with fixing whole platform, between four steel pipe leg posts 3 some supporting steel pipes 5 are set, these supporting steel pipes 5 and firm truss-like jacket 2 of four steel pipe leg post 3 common compositions support upper module 1.In the framework of jacket 2, some waterproof casings 6 can be installed as required.Concrete when offshore platform is installed, generally be divided into for two steps, at first jacket 2 is transported to the scene, four steel pipe leg posts 3 of jacket 2 in, piling bar 4 is inserted and squeezes into the seabed, after jacket 2 is fixed, upper module 1 is shipped be installed on the jacket 2 again.
The offshore platform that adopts this method to build up, structure is more stable, is fit to very much be operated under the complicated marine environment condition.Yet, because this form of structure weight is bigger, to install and more complicated, the cost nature is just higher.In some seas in the exploitation of small field and marginal field, often to use some simple and easy platforms, generally speaking, the well head number of simple and easy platform is less, production facility is simple relatively, and is the operating platform that nobody garrisons, and weight of equipment is far smaller than conventional production platform, under this condition, still use conventional jacket-type structure, very non-remunerative beyond doubt.
The utility model content
The purpose of this utility model provides the simple and easy production platform of small field and marginal field exploitation in a kind of suitable sea, makes its needs that can fully satisfy ordinary production, and structure not only lightly but also be convenient to install.
The purpose of this utility model is achieved through the following technical solutions.
A kind of three simple and easy platforms of only leg that are suitable for small field and marginal field exploitation in the sea, form by upper module with in substructure, it is characterized in that described substructure, its center is a pillar with single leg, the periphery is three sleeve assemblies, be linked to be an integral body by some supporting steel pipes between pillar with single leg and three sleeve assemblies, some upper support are installed between upper module and the pillar with single leg.
The purpose of this utility model can also further realize by the following technical programs.
Aforesaid three simple and easy platforms of only leg that are suitable for small field and marginal field exploitation in the sea, its sleeve assembly are by piling bar and be enclosed within the outer steel pipe sleeve of piling bar and form, between piling bar and steel pipe sleeve by cemented.
It is (can change at ± 10 degree) on concentrically ringed three Along ents in the center of circle that aforesaid three simple and easy platforms of only leg that are suitable for small field and marginal field exploitation in the sea, its three sleeve assemblies are positioned at the pillar with single leg.
Aforesaid three simple and easy platforms of only leg that are suitable for small field and marginal field exploitation in the sea, its pillar with single leg is by the steel pipe manufacturing, steel duct is equipped with waterproof casing, pump pillar, standpipe and cable protecting tube etc., and anti-ice piton body (only to the ice marine site is arranged, other marine site is not adorned) is equipped with in the outside.
Aforesaid three simple and easy platforms of only leg that are suitable for small field and marginal field exploitation in the sea are installed some upper support between its pillar with single leg and the upper module.
Adopt the simple and easy platform of the utility model technology to compare with traditional jacket platform, under the prerequisite that satisfies the offshore production job requirements, owing to simplified numerous and diverse space frame structure, both reduced rolled steel dosage significantly, shortened construction duration again significantly, thereby its construction cost is descended greatly.And because simple and easy platform and integrally weight is lighter, superstructure and substructure can integral constructings, can disposablely finish marine lifting operation, with jacket platform the method that need proceed in two phases are installed and compare and saved installation cost.In addition, because waterproof casing, pump pillar, standpipe and cable protecting tube etc. are installed in column inside, make its many again one deck protections.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that adopts the production platform of conventional jacket-type structure.
Fig. 2 is the structural representation that adopts the simple and easy platform of the utility model technology.
The specific embodiment
With reference to Fig. 2, upper module 11 is supported on the substructure 12, as required some production facilities can be installed on it; The center of substructure 12 is a pillar with single leg 16, this pillar with single leg 16 is by the steel pipe manufacturing, the periphery is three sleeve assemblies 13, connect into an integral body by some supporting steel pipes 15 between pillar with single leg 16 and three sleeve assemblies 13, some upper support 19 are installed between upper module 11 and the pillar with single leg 16.Sleeve assembly 13 is made up of piling bar 14 and the steel pipe sleeve 18 that is enclosed within outside it, and by cemented; It is on concentrically ringed three Along ents in the center of circle that three sleeve assemblies 13 should be positioned at pillar with single leg 16; Anti-ice piton body 17 is installed in outside the pillar with single leg 16, can reduce environmental loads such as ice marine site floating ice is arranged to the influence that platform produces, and especially can reduce the influence that the ice excited vibration produces topside facility; Waterproof casing 20 is installed on the steel duct of pillar with single leg 16, makes its many again one deck protections.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
