Description
Technical field
The utility model relates to a kind of production platform, particularly relates to the simple and easy production platform of a kind of offshore oil exploration and exploitation.
Background technology
The offshore oil development mode is mainly " 31 pattern ", i.e. a fixed platform, a submerged pipeline, a submarine cable.Carry out the rolling development in oil field through the collocation of central platform and wellhead platform, the oil of wellhead platform extraction is transported to central platform through submerged pipeline and is concentrated and carry out preliminary treatment, and then the reason of the terminal processes factory and office on island back is outer defeated near transporting to.The electrical network supply that the electric power of wellhead platform and central platform is made up of submarine cable.
The marginal small oil field in coastal waters has usually that reserves are little, the exploitation time limit is short, can rely on characteristics such as the platform distance is far away apart from periphery.Because the stratigraphic structure of these marginal small oil fields is complicated, exploration operation is not enough, therefore also have the characteristics that reserves are uncertain, possibly have potentiality to be exploited simultaneously.
For above-mentioned marginal small oil field, existing technical conditions can't be carried out economic exploitation.If under the uncertain situation of reserves, adopt " 31 pattern " to develop, then economic risk is too high; If calling offshore boring island carries out production testing operation, then operating cost is too high.Therefore, seek a kind of development tool of economic and reliable, the proved reserves Xingqi economic development of going forward side by side is a present ocean marginal oil field problem demanding prompt solution.
The utility model content
The utility model provides a kind of offshore oil exploration and exploitation simple and easy production platform for solving the technical problem that exists in the known technology, can realize to economic and reliable the pilot production production operation of marginal small field, promotes the development of marginal small field.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the simple and easy production platform of a kind of offshore oil exploration and exploitation, comprise spud leg and the main platform body that is connected with spud leg, and said spud leg is provided with hydraulic bolt formula elevating mechanism; Said main platform body is provided with bank, production of hydrocarbons treatment region, power-equipment district, control and living area; Said main platform body is provided with crude oil tank, ballast tank, production water tank, sea water tank, fresh-water tank and mechanical cabin; Said main platform body stern is provided with well head centralizing bracket and well workover district; Said main platform body two topsides are provided with the crude oil exporting device.
Said well head centralizing bracket is two story frame structures, and is provided with a plurality of well slots.
Said crude oil exporting device is the truss-like oil transfer arm.
Advantage and the good effect that the utlity model has are: collection production, oil storage, outer defeated, engineering are propped up and are held in one, do not need wellhead platform and are used for outer defeated anchoring system.Reserved the mounting interface and the space of workover rig simultaneously, installed and withdraw easy, need not call large-scale maritime works's boats and ships such as crane barge, expense is low; When changing the exploitation find, can realize well head, the integral moving of producing oil storage platform, outer transfer device, can realize to economic and reliable the pilot production production operation of marginal small field, promote the development of marginal small field.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 3, the simple and easy production platform of a kind of offshore oil exploration and exploitation, main platform body 1 plane is rectangular; Be provided with the spud leg 2 of four bands shoe 3; Spud leg 2 adopts hydraulic bolt formula elevating mechanism, and steel is non-from boat, possesses the ability of in marine site, the multiple district of typhoon, stablizing operation; Can resist a-hundred-year adverse circumstances, can carry out operation in the following depth of water of 50m zone.Platform leg 2 is packed up during towage; See also Fig. 1; Adopt that tugboat is wet to be dragged or after the dried mode such as drag of semi-submerged ship transports to place in place, oil field, under floating state, transfer spud leg 2 through hydraulicefficiency elevation structure, spud leg 2 is inserted desired depth in the mud through platform self and Ballast Water weight; Realize marine stable standing, see also Fig. 2.Platform has the easy-to-install characteristics, and large-scale maritime works's boats and ships such as need not calling crane barge when withdrawing are installed, and installation, towage, Back-end load are low.
Platform one deck deck bow, stern are provided with hydraulic windlasses, and bow is provided with two cover towing systems, is used for platform towage and in place.Two topsides are provided with crude oil exporting device 4.On one deck deck bow also be provided with between carbon dioxide, system nitrogen district; 4m place, top, middle part, one deck deck is provided with Tween deck, and the Tween deck rear portion is the production of hydrocarbons treatment region, and the front portion is power-equipment district, control zone and boiler area, and bow is the living area.
Platform adopts modularized design, and production of hydrocarbons module 7, workover rig module 6, accommodation module 8 and outer transfer device module can be installed and used according to the production demand.When changing the exploitation find except waterproof casing etc. the underground device, can be easily with all overground installation integral moving.
