Abstract
An oil gas displacement type underwater oil storing device consists of a main tank body, an oil inlet pipeline, an oil outlet pipeline, a gas inlet and outlet pipeline, a water inlet and outlet pipeline and a gas storing tank. The gas storing tank is filled with high-pressure nitrogen which is a kind of inert gas, and is more stable, is lower than oil in density, positioned at the upper part of the oil all the time, and can not be dissolved with oil. By utilizing the oil gas displacement, namely the principle that the nitrogen is compressed when oil enters, the nitrogen is released when oil is discharged, and the gas can be compressed, the function of underwater oil storing can be realized. The device can avoid the oil-water mixture caused by the original oil water displacement, the pollution is reduced, simultaneously, the high-pressure nitrogen is the commonly used inert gas, so that the cost is low and the oil gas displacement is easy to realize.
Description
Technical field
The utility model relates to a kind of seabed Fuel Tanking Unit of field of ocean engineering.
Background technology
Oil-gas gathering and transportation mainly comprises oil storage space and the oil gas treatment facility that FPSO, semisubmersible platform etc. are attached troops to a unit in the development of the field of deep-sea at present; These facility common features are that oil gas is handled and the main floating mode facility that relies on of storage; The Floating Production pattern can be regarded as mature technology in the world, has many preceences, but owing to receive the great force of marine stormy waves; No matter be that offshore structure or its lashing system cost are high; And along with the increase of the depth of water, technical risk is increasingly high, and the facility cost sharply raises.Under the prerequisite that solves oil gas primary treatment problem under the high undersea hydrostatic pressures condition, the defeated pattern of the collection effective way of can yet be regarded as under water.Obtain exploitation simultaneously along with marginal oil field is increasing, Fuel Tanking Unit will become a kind of trend under water.Fuel Tanking Unit is that profit is isolated under water at present, and its liner material is that the requirement of profit isolated material is very high, and profit isolation place can form the profit mixing.
Summary of the invention
The shortcoming that the utility model mixes for existing Fuel Tanking Unit profit under water; Oil gas displaced type Fuel Tanking Unit is under water proposed; Fuel Tanking Unit adopts (former) oil (nitrogen) gas substitute mode under water, can avoid producing profit and mix, for later Fuel Tanking Unit under water provides a new oil storage method.
The technical scheme that the utility model technical solution problem is adopted is that oil gas displaced type Fuel Tanking Unit under water is made up of main tank body, chargine line, fuel-displaced pipeline, intake and exhaust pipeline, intake-discharge pipe road and storage tank.Storage tank is equipped with high pressure nitrogen, and nitrogen is unreactable gas, and is more stable, and its density ratio oil is low, be in the top of oil, and both is immiscible always.Utilizing the oil gas displacement is oil-feed compressed nitrogen, fuel-displaced release nitrogen, and the principle of work that gas can compress realizes oil storage function under water.
The beneficial effect of the utility model is the oil water mixture that can avoid oil and water displacement in the past, reduces and pollutes, and high pressure nitrogen is for unreactable gas commonly used simultaneously, and with low cost, the oil gas displacement is easy to realize.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is Fuel Tanking Unit scheme drawing under water.
1-main tank body wherein; 2-chargine line; 3-fuel-displaced pipeline; 4-intake and exhaust pipeline; 5-storage tank; 6-advance discharge port.
The specific embodiment
As shown in Figure 1, utilize buoyancy to be dragged to the work place, inject seawater through advancing in 6 pairs of main tank bodies 1 of discharge port, sink under the water.After accomplish installing, discharge the seawater in the main tank body 1 and open storage tank 5 valves simultaneously, utilize difference of pressure nitrogen to get in the tank bodies through intake and exhaust pipeline 4 and reach the state that is full of, structure gets into mode of operation.When carrying out oil storage, rely on oil pressure crude oil to be injected in the jar through chargine line 2, nitrogen will progressively be compressed to storage tank 5; When crude oil is exported, utilize pumping system suction crude oil, crude oil is through fuel-displaced pipeline 3 outputs, and nitrogen is with automatic filling space.When needs were shifted, in tank body, being full of nitrogen, that the oil storage tank body is risen was floating.
Claims (1)
- The oil gas displaced type under water Fuel Tanking Unit form by main tank body, chargine line, fuel-displaced pipeline, intake and exhaust pipeline, intake-discharge pipe road and storage tank; Storage tank is equipped with high pressure nitrogen; Utilize pressure official post nitrogen to get in the tank body and reach the state that is full of through the intake and exhaust pipeline; When carrying out oil storage, rely on oil pressure crude oil to be injected in the jar through chargine line, nitrogen will progressively be compressed to storage tank; When crude oil is exported, utilize pumping system suction crude oil, crude oil is through fuel-displaced pipeline output, and nitrogen is automatic filling space, and when needs were shifted, in tank body, being full of nitrogen, that the oil storage tank body is risen was floating.
