Abstract
The utility model discloses a spherical steam-water separator which is matched with a thermal recovery steam injection boiler for increasing steam dryness fraction in oilfields. The spherical steam-water separator comprises a spherical container, a steam-water inlet and a steam-water outlet are arranged on the spherical container, a steam outlet is arranged on the spherical container, a cyclone separator is placed in the spherical container, a pressure transmitter and a liquid level meter are arranged outside the spherical container, and a safety valve is arranged on the steam outlet. According to the spherical steam-water separator, the cyclone separator in the spherical container is an effective steam-water separating device, and one separation efficiency of the cyclone separator reaches up to around 99%; and the spherical steam-water separator is capable of effectively improving the dryness fraction of steam, meeting the requirement of the high dryness fraction steam required for high-turn exploitation in the oilfields, and greatly improving the recovery efficiency of crude oil.
Description
One, technical field
The utility model belongs to oil thermal recovery injection boiler auxiliary facility, the supporting special equipment in particular for improving steam quality.
Two, background technology
Along with deepening continuously of thickened oil recovery, the growing needs of thickened oil recovery new technology can not have been satisfied with the method for conventional boiler (80% steam quality) steam injection.Show that according to newest research results the steam quality effect that the high round exploitation in viscous crude later stage must be injected more than 95% is just better.And at present at the injection boiler of usefulness, owing to receive the restriction of its water treatment facilities, its highest steam quality is 80%, and is merely about 70% during actual motion, and this has had a strong impact on the performance of heating exploitation effect.The carbonated drink separation equipment is applied to injection boiler has had the history of more than ten years; But for various reasons; Equipment is difficult to adapt to each oil field complex geological conditions, causes defectives such as its separative efficiency is low, operating condition is unstable, noise is big, makes equipment not give full play to due effect.
Three, summary of the invention
The purpose of the utility model provides a kind of high mass dryness fraction in injection boiler terminal that is applicable to and annotates the spherical steam-water separator of vapour, to satisfy the steam quality requirement, improves the heating exploitation effect.
The technical scheme that the utility model adopts is: spherical steam-water separator comprises a spherical container, and the outlet of carbonated drink import and carbonated drink is arranged on spherical container, and steam (vapor) outlet is arranged above the spherical container; In spherical container, place cyclone separator; In the spherical container outside pressure transmitter and liquid level gauge are arranged; Safety valve is arranged on steam (vapor) outlet.
The utility model is according to the characteristics of oil field service condition (pressure and flow are unstable); Check through to various parameters is calculated; Under the prerequisite that obtains the maximum separation space, carry out design optimization, selected spherical container; Four independently cyclone separators are set in container, can increase and decrease the open and close quantity of cyclone separator according to load condition.The separation process of two-phase fluid is quite complicated, realizes by the comprehensive effect of several kinds of centrifugations often.Cyclone separator combines centrifugation, Gravity Separation and membrane type centrifugation and carries out carbonated drink separation.Tangentially introduce the cylindrical shell of cyclone separator by the next steam water interface of boiler export with very big kinetic energy; It is changed into by rectilinear motion revolve motion, form centrifugal force (force of gravity is big 17.9～47.5 times), because vapour and water exist severe poor; Vapour spiral in the whirlwind tube rises; Form the vapour post, water then throws to barrel and rotation descends, and in tube, forms parabolic; Also have small quantity of water droplets to be brought into the air space at whirlwind tube middle part by steam flow, these water droplets are pushed to wall gradually in the spiralling process with steam flow.Introduction pipe through being arranged on vapour, hydrospace is continuously drawn vapour, water, reaches the purpose with vapour, separated form water at last.
Cyclonic separation is a kind of very effective water separator in the pot that the utility model adopts, and its separative efficiency is up to about 99%.The use of spherical steam-water separator has improved the mass dryness fraction of steam effectively, has satisfied the requirement of the high round exploitation in oil field needs high-quality steams, has improved the recovery ratio of crude oil greatly.
Four, description of drawings
Accompanying drawing is the structural representation of the utility model.
Five, the specific embodiment
The utlity model has a spherical container 1, carbonated drink import 2 and carbonated drink outlet 3 are arranged in spherical container 1 bottom, steam (vapor) outlet 4 is arranged above the spherical container 1.Cyclone separator 5 is set in spherical container 1.Pressure transmitter 6 and liquid level gauge 7 are arranged in spherical container 1 outside; Safety valve 8 is arranged on steam (vapor) outlet 4.
Said cyclone separator 5 is 4 independently cyclone separators.Above cyclone separator 5, louver separator 9 is set, makes the carbonated drink secondary separation near spherical container steam (vapor) outlet 4 places; In cyclone separator 9 porch equal steam vent plate 10 is arranged, with prevent vapour, water flow velocity is inhomogeneous and influence separating effect.Be provided with saturated vapor sampler 11 and sampling cooler 12 at steam (vapor) outlet 4 places, be used for the sampling of saturated vapor sample circuit cooling steam.In spherical container 1 bottom sewage draining exit 13 is arranged; There is filter 14 at 3 places at the stove water out, and Liquid level adjusting valve 15 is arranged on the carbonated drink outlet connecting pipe.
