Description
Technical field
The invention belongs to offshore and gas development field, more particularly to a kind of for the isolated underwater soft of offshore oil and gas field
Property storage device.
Background technology
There are two types of methods after offshore oilfield output crude oil to carry out subsequent processing：1) it is exported with submarine pipeline；2) it is stored in
It is periodically transported in Fuel Tanking Unit with shuttle tanker, which can be a fixed component part of production platform, also may be used
To be an individual structure.If the yield of an offshore oilfield is not big enough, being laid with expensive pipeline under the ocean must not
Mistake is repaid, to exploit in this case can only just use certain low cost but safe and reliable Fuel Tanking Unit.
Where essential Fuel Tanking Unit is more particularly arranged at.There are three optional positions：1) it is more than Water Plane and fixed
In platform topsides chunking；2) as a part for floating structure on the water surface；3) as platform understructure below Water Plane
A part is used as an individual facility.Fuel Tanking Unit below Water Plane is needed through piping and platform production group
Block is connected come the handling operation for carrying out crude oil.Three positions respectively have excellent, shortcoming in practical applications.1) more than Water Plane
When：Fuel Tanking Unit is placed directly within usually as a fixed part of upper strata chunking under technical module and accommodation module.Advantage
It is not influenced by the ocean current power that wave and tide generate.However, huge Fuel Tanking Unit is placed in technical module and life mould
Serious security risk can be formed under block.In addition, worse this be laid out increases huge weight to table top, make
Very big weight change is generated in crude oil cargo handling process, so as to greatly affected the motor imagination feature of platform.Therefore,
This scheme is only applied on the fixed platform positioned at Very Shallow Water domain on a small quantity at present.2) in the water surface：Advantage is can be easy to
Ground increases oil storage volume of the platform similar to ship shape FPSO floating structures.But shortcoming is, the environment that floating structure is easily generated by stormy waves
The influence of power, so as to need to keep marine positioning, therefore can be than routine by expensive a mooring system or alignment system
Fixed platform cost it is much higher.For this purpose, the oil pipeline reality that floating structure only recovers the oil required in deepwater production or shallow water
It can just be used when cost is too high.3) below Water Plane：For fixed platform or floating platform, this is all best
Position, as long as because the underwater depth of oil storage tank is deep enough, the environmental forces generated by wind just completely disappears, and is generated by wave
Environmental forces can also weaken significantly.In addition, the center of gravity of platform can also decline, be conducive to the dynamic characteristics and fortune of platform on the whole
Dynamic response.But underwater oil storing device can face many challenges.Most stern challenge be how to handle generated during loading and unloading oils it is huge
Big buoyancy and the variation of corresponding platform weight.
Usually there are two types of methods to store processed crude oil or other liquid hydrocarbons for fittings storage device.First
Kind is " wet type oil storage method ", i.e., oil and seawater is stored in together in same oil storage tank.Due to density difference, crude oil or liquid
Hydrocarbon can float on the top of oil storage tank, although and grease can be in direct contact the two can nature be divided into up and down two layers.
In loading operation, for processed crude oil by injection oil storage tank, the seawater of simultaneous equal can be discharged out oil storage tank, so as to make
The volume of oil storage pot liquid remains unchanged.The process of emptying is exactly the opposite, seawater by injection tank and the crude oil of equivalent is squeezed
Go out outside tank.The seat bottom weight change very little of storage tank when the great advantage of the oil storage method is loading and unloading oils, variable quantity are only maximum seat bottom
15% or so of weight.Another advantage is, due to pressure of the storage tank in entire service life inside it and external seawater
It remains the pressure balance of hydrostatic, therefore does not need to it being designed to pressure vessel.However, this method also has three to lack greatly
Point.First is exactly the worry of environmental pollution.Since storage tank constantly shakes under water, the contact surface of crude oil and seawater can generate
As soon as mixed layer, which, which such as discharges, can cause environmental pollution.Second is heat-insulating problem, and oil keeps liquid that need to add
Heat heat preservation, and the external water come in is cold, therefore the contact of grease large area is difficult to take Insulation to crude oil.Third,
This method can not store water-soluble liquid, such as methanol.Just because of these shortcomings, particularly problem of environmental pollution, although industry
Interior personage has made huge effort, but wet type oil storage method either obtains practical application in fixed platform or floating platform
Case is few.
The method of second of oil storage is " dry type oil storage method ".It will not be in direct contact, therefore no matter handled using this method grease
The crude oil or liquid hydrocarbon crossed can be stored in underwater storage tank.In addition, crude oil can be kept the temperature well.No
It crosses, this method faces two serious challenges.First, a large amount of buoyancy can be generated during emptying.Secondly, it needs to use indifferent gas
Body, and inert gas leakage can cause environmental pollution.Closing oil storage tank oil reservoir superjacent air space is injected inert gas into prevent
The gas of crude oil volatilization leaks out storage tank and causes air pollution.However, the generation of inert gas, injection and form sealing in
The processes such as layer, exhaust may all leak and as pollution sources.In above-mentioned multiple serious challenges, eliminate a large amount of buoyancy and ask
The solution of topic typically uses the gravity foundation of a cement manufacture to offset the buoyancy generated during emptying.Other one
Kind of the method for solving excessive buoyancy is that several ballast tanks are in addition built on oil storage tank side, is supported toward water filling in ballast tank during emptying
Disappear the buoyancy integrally generated.No matter which kind of method can all make entire storage device very heavy in itself.Above-mentioned variety of problems makes to do
The case that formula oil storage method obtains practice in offshore oil production industry is seldom, most in only case to be applied to cement
Gravity foundation platform.
On October 23rd, 2012, american documentation literature US8292546B2 disclosed a kind of specific side of dry type oil storage method
Case proposes a wet tank with a corresponding seawater ballast tank, and the two is symmetrical, is all injected with above two pot liquids
Inert gas and intercommunication.The Fuel Tanking Unit constantly carries out grease weight by two sets of oil/water pumping systems and puts during oil loading and unloading
The consistency of holding meanss gross mass is brought, while device center of gravity may only be moved up and down along an axis.The maximum of the system
Advantage is that the total weight of device is always consistent during loading and unloading oils.However, the device has three.First,
The actual reserves of device entirety are very low, because more than 50% volume of system is required to storing seawater and inert gas.Therefore,
The excessive buoyancy more than 50% can be generated during dry type oil storage method emptying, and wet type oil storage method only generates about 15% buoyancy.In order to
It solves the problems, such as above-mentioned excessive buoyancy, usually using heavy cement structures rather than uses the common Steel material of offshore platform.
Cement structures directly sit bottom, easily generate undermining and empty phenomenon, cause a hidden trouble to platform safety.Second, due to seawater pressure
The presence of weight tank increases the overall weight of device.Third, the effective operation of entire Fuel Tanking Unit need dependence can be to oil storage
Tank and crude oil in ballast tank or seawater are carried out respectively with the complicated combination pumping system taken out with row, which exists long-term
The security risk of reliability service.
