Description
Technical field
The present invention relates to a kind of oil field oil storage tank, specially a kind of offshore oil field base type seabed oil storage tank.
Background technology
In recent years, as China's economy grows continuously and fast, the dependence for basic energy resource is increasing.Oil conduct
Basic energy resource product, the upstream of production industry, its production and marketing and import and export change, the change with economic situation are closely related.Nowadays
China be world oil consumption the second big country, only 2014, even if being influenceed by domestic economy environment change, China's stone
Oil consumption has also reached 8.67 hundred million tons, slows down 12.5 percentage points compared with the amplification of 2013 18.6%.China's refined oil table
It is 7.15 hundred million tons to see consumption figure, increases by 22.9% on a year-on-year basis, the amplification than 2013 5.9% then accelerates 5 percentage points.It is comprehensive complete
See in year, China's oil consumption still keeps very fast speedup, increase obvious especially in product oil import volume.China's oil disappears within 2015
The amount of expense is estimated will to be continued to increase.Now is increasing for the demand of petroleum reserves, and the dependence to Imported oil is further
Rise, and domestic storage level is seldom, far away from developed country, energy security problem can not be ignored all the time, set up national oil war
Slightly lay in very urgent！
It can thus be seen that China must strengthen the exploitation to submarine oil and deposit.However, with sea oil drilling and production
The development of operation, offshore oilfield gang of wells quantity will roll up, and yield can also be substantially improved, and alleviate the same of current energy crisis
When, the accumulating ability of marine storing and transporting system, efficiency and work continuity requirement are also improved constantly！Each production relevant department requires
Increase has larger oil storage capacity, construction independently of the provisional oil storage facility outside offshore oil production platform, to make up fortune oil
The discontinuity that boatman makees produces the adverse effect brought to oil field.
The content of the invention
It is an object of the invention to provide a kind of offshore oil field base type seabed oil storage tank, possess using safety, using the longevity
Life is long, environmental protection is good, save occupation of land, advantage easy to maintenance, solves existing oil field oil storage tank safety in utilization difference and uses the longevity
The problem of ordering short.
To achieve the above object, the present invention provides following technical scheme：A kind of offshore oil field base type seabed oil storage tank, bag
Oil tank main body, inner bag, movable floor and base are included, the oil tank main body is provided with closure, and oil tank in cylindrical structural top
Body interior is provided with the top of inner bag, the closure and is provided with oil filling pipeline, outlet line, loading line and sewage suction pipe side by side,
The sewage suction pipe is stretched into inside inner bag, is hollow structure, the hollow structure between the inwall of inner bag and the oil tank main body
It is interior to be provided with heat-insulation layer.
It is preferred that, the oil tank body side is provided with into discharge outlet close to the bottom of oil tank main body, it is described enter discharge outlet, fill
Air pipe is provided with valve, and oil filling pipeline, outlet line and sewage suction pipe are provided with one-way control valve.
It is preferred that, installation activity bottom plate in the oil tank, movable floor is provided with heater.
It is preferred that, isolation cloth, isolation cloth and movable floor edge airtight connection are embedded with the middle of the inner bag side wall.
It is preferred that, the heat-insulation layer uses polyurethane expanded material.
Compared with prior art, beneficial effects of the present invention are as follows：
1st, the present invention by water, crude oil enter row, and simultaneously coordinate inflation/deflation can increase the speed of nearly oil extraction, improve
Operating efficiency.
It is 2nd, of the invention by being embedded with isolation cloth, isolation cloth and movable floor edge airtight connection in the middle of the inner bag side wall,
So as to be isolated between crude oil and seawater by isolation cloth and movable floor, heated when oil tank is built with crude oil in movable floor, heat
Amount reaches the purpose to heating crude oil, while passing through the hollow knot between inner bag and the inwall of oil tank main body by lower and upper propagation
Heat-insulation layer is provided with structure, insulation can be played a part of to the crude oil inside inner bag.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure：1- oil tank main bodys, 2- isolation cloths, 3- enters discharge outlet, 4- oil filling pipelines, 5- outlet line, 6- loading lines,
7- sewage suction pipes, 8- movable floors, 9- inner bags, 10- bases.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 1, the present invention provides a kind of technical scheme：A kind of offshore oil field base type seabed oil storage tank, including oil
Can body 1, inner bag 9 and movable floor 8, the oil tank main body 1 are provided with closure, and oil tank main body 1 in cylindrical structural top
Inside is provided with the top of inner bag 9, the closure and is provided with oil filling pipeline 4, outlet line 5, loading line 6 and sewage suction pipe 7 side by side,
The sewage suction pipe 7 is stretched into inside inner bag 9, is hollow structure between the inner bag 9 and the inwall of oil tank main body 1, described hollow
Heat-insulation layer is provided with structure.
The bottom of oil tank main body 1 is provided with into discharge outlet 3, loading line 6 and is provided with valve, oil filling pipeline, outlet line
One-way control valve is provided with sewage suction pipe.
It is provided with the inner bag 9 in the middle of movable floor 8, the side wall of inner bag 9 and is embedded with isolation cloth 2, isolation cloth 2 and movable floor 8
Edge airtight connection, the heat-insulation layer uses polyurethane expanded material.
Operation principle：Oil tank main body is mounted at the 15m depth of waters, is dragged to behind precalculated position, by various pipelines and accordingly
After facility waterborne is connected, pressurization carries and storage tank sinks under the water, and extraneous water enters inner bag and picking-up activity by entering discharge outlet 3
Bottom plate 8 is moved upwards, and crude oil injects inner bag 9 by oil filling pipeline 4, and crude oil compressing movable floor 8 is moved downward water drain tank
Outside, because oil is lighter than water, oil is constantly in tank body top, when fuel-displaced, opens the valve in outlet line 5, crude oil is in extraneous water
The lower outflow (pumpable if necessary) of pressure effect, extraneous water automatic filling original space, during storage wet crude, aqueous original
Most of free water in oil can be settled down to bottom, can be suctioned out and post-processed by sewage suction pipe, when because of maintenance or oil field exhaustion etc.
When other reasonses need to remove underwater storage tank, inflatable drainage makes to can be shifted after tank body floating, and oil storage tank leaves loading line 6,
The balance of tank inside and outside differential pressure can not only be ensured, and ensure that oil storage tank, by less seawater pressure action, improves tank body
Intensity, meanwhile, coordinate inflation/deflation to increase the speed of nearly oil extraction, improve operating efficiency.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
