Description
Technical field
The present invention relates to a kind of U-shaped foam ring generating device and the methods for generating foam ring using the device, belong to heavy
Crude oil adopts the technical field of defeated drag reduction.
Background technique
Currently, heavy crude belongs to the energy field of emphasis exploitation, the component contents such as resin and asphalt therein are high, by
It is high in density, viscosity is big, poor fluidity feature, it is made easily to be adhered to tube wall, cause adopt it is defeated during need to provide foot
Enough energy, for overcoming flow resistance.In addition to this, high wax content oil has high condensation point, and wax is easily precipitated in flow process
Crystalline substance, leads to line clogging, and these problems all bring very big challenge to the exploitation and conveying of heavy crude.
The technique for adopting defeated heavy crude both at home and abroad mainly has dilution, heating, adding active water, mixed with hot water, crude oil modification and low
The methods of viscous Liquid jacket transportation.But these traditional heavy crude drag reduction techniques all have certain drawbacks: dilution method requires dilute
The supply of oily resource is reliable and stable；The energy consumption of heating is high, tends to have solidifying manage-style danger；The watering quantity of adding active water method and method mixed with hot water
Greatly, pipeline corrosion and fouling are serious；Crude oil modifies method the high requirements on the equipment, investment greatly；The Emulsifying later period needs to carry out brokenly
Cream processing.
As a result, from macro-effect, improve in the flow behavior method of heavy crude, Liquid jacket transportation and foam conveying
Heavy crude Drag Reduction effect be significant.Therefore, two big drag reduction methods, Ke Yisheng are conveyed in conjunction with Liquid jacket transportation and foam
At foam ring, the drawbacks of developing a kind of device, heavy crude transporting resistance and the above method can be effectively reduced.
Summary of the invention
The present invention, which combines, to be generated foam and two processes of foam ring occurs, and a kind of U-shaped foam ring generating device is provided.
The present invention provides a kind of U-shaped foam ring generating device, comprising: foam liquid pipe, U-tube, oil inlet pipe, grid, drainage
Plate.Foam liquid pipe consists of two parts, i.e. inlet tube and the reducing pipe with perforation；U-tube consists of three parts, i.e. air inlet
Pipe, blending pipe and at endless tube.Specifically, above-mentioned foam liquid pipe shares two kinds of conduit types, reducing pipe end seal is conducive to
Foam solution is uniformly sprayed from perforation, is mixed well with air along perpendicular to tapered tube wall direction；Grid is dispersed in foam
In circular passage；Oil inlet pipe end and cyclic pipe end will form it into stable foam pendular ring there are certain length；Oil inlet pipe
Intermediate position and between endless tube be equipped with six pieces of trapezoidal drainage plates, be spaced each other 60 ° and be distributed in annular channel, by annular chamber
Room is evenly divided into six independent flow passages, and drainage plate is parallel with heavy crude flow direction, which can effectively reduce water flow
Radial displacement keeps the foam solution ring structure to be formed more stable, and since the contact area of runner and outside pipeline is larger, this is advantageous
Outside pipeline flowing is invested in foam；The U-shaped foam ring generating device share 1 air inlet, 1 inlet, 1 oil inlet and
1 using foam as outer ring, pay attention to crude oil center heavy crude-foam ring-type outflux.
The attainable beneficial effect of institute of the invention includes:
Projected conducive to foam solution along tapered tube wall direction 1. foam solution pipe end is sealed with, it is evenly dispersed in the duct, and
The blending of Y type is formed with air, is blended compared to T-type, momentum loss is reduced.
2. using this U-shaped foam ring generating device, it is applied in heavy crude drag reduction, can form foam is outer ring, heavy
Crude oil and keeps good flow stability apart from interior quite long in the heavy crude-foam annular flow at center, due to being
Foam rather than heavy crude are directly contacted with tube wall, be can effectively reduce the flow resistance of heavy crude, are improved the defeated of heavy crude
Send efficiency.
3. foam ring close to the wall of the tube slows down heavy crude to a certain extent and exchanges with extraneous heat, thus
It can effectively reduce the amount of precipitation of wax crystalline substance, and reduce adherency and asphaltene deposits of the wax crystalline substance on tube wall in tube wall.
4. have the function of two class device of foam maker and pendular ring generator simultaneously, it is cheap, it is worth in heavy original
Further genralrlization application in the exploitation and conveying of oil.

Specific embodiment
Present invention is further described in detail with reference to the accompanying drawings and detailed description.
The present invention provides a kind of U-shaped foam ring generating device, comprising: foam liquid pipe, U-tube, oil inlet pipe, grid, drainage
Plate.Foam liquid pipe consists of two parts, i.e. inlet tube (1) and the reducing pipe (3) with perforation (2)；U-tube is by three parts group
At i.e. air inlet pipe (4), blending pipe (5) and at endless tube (6).Specifically, above-mentioned foam liquid pipe shares two kinds of conduit types, gradually
The draw (3) end seal, cone angle are 30 °, are conducive to foam solution edge perpendicular to reducing pipe (3) tube wall direction, from perforation
(2) it uniformly sprays, mixes well with air；Grid (7) is dispersed in foam in circular passage；Oil inlet pipe (9) end with
At endless tube (6) end stable foam pendular ring is formed it into there are certain length；The intermediate position of oil inlet pipe (9) and cyclization
It manages and six pieces of trapezoidal drainage plates (8) is housed between (6), be spaced each other 60 ° and be distributed in annular channel, by annular compartment even partition
At six independent flow passages, drainage plate (8) is parallel with heavy crude flow direction, which can effectively reduce the radial position of water flow
It moves, keeps the foam solution ring structure to be formed more stable, since runner and the contact area at endless tube (6) are larger, this is conducive to steep
Foam invests into endless tube (6) flowing；The U-shaped foam ring generating device share 1 air inlet (10), 1 inlet (11), 1 into
Hydraulic fluid port (12) and 1 are using foam as the heavy crude of outer ring-foam ring-type outflux (13).It is former that heavy is reduced using above-mentioned apparatus
Oily transporting resistance, including following basic step:
1. inlet (11) is connect with foam liquid pipe, air inlet (10) is connect with tracheae, by oil inlet (12) and again
Matter crude oil-foam ring-type outflux (13) is connect with upstream and downstream pipeline respectively；
2. closing upstream heavy crude pipeline valve and foam solution pipeline valve, tracheae valve is opened, by air inlet (10)
Air is injected to device；
3. heavy crude pipeline valve in upstream is kept to close, foam solution pipeline valve is opened, from inlet (11) to device
Interior injection foam solution；
4. foam solution is sprayed from the perforation of reducing pipe (3) tube wall, it is dispersed in pipeline, and mix well with air,
Uniform and stable foam is formed by grid (7) again, enters annular compartment, six chambers separated via drainage plate (8) later
Annular channel is then left in room, then flows into downstream line after heavy crude-foam ring-type outflux (13) outflow；
5. to foam flowing it is steady after, open heavy crude upstream line valve, heavy crude from oil inlet (12) into
Enter device, gradually eject the foam in oil inlet pipe (9), it is outer ring, heavy that heavy crude, which forms foam in oil inlet pipe (9) end,
Heavy crude-foam annular flow of the crude oil at center；
6. heavy crude-foam annular flow is after at certain distance is flowed in endless tube, into downstream line, since foam is straight
Connect and contacted with tube wall, greatly reduce frictional resistance, reduce heavy crude conveying pressure drop, foam separated heavy crude and
Tube wall can effectively reduce heavy crude and be radiated outward by tube wall, slow down wax partial crystallization and settle out with asphalitine；
7. if desired stop heavy crude conveying, first close heavy crude upstream line valve, run a period of time after according to
The gentle tube valve of secondary closing foam solution pipeline valve.
