The device has the advantages of fair design, and can be used to get the mixing gas with carbon dioxide and nitrogen with the boiler flue gas and inject the mixing gas into the well as the boiler producing steam thick oil, therefore obtains the good effect in increasing crude oil production and environmental protection.
Description
Technical field:
The present invention relates to a kind of equipment of forming a complete and comprehensive system for collecting real estate fees that is used for thickened oil recovery, belong to gas isolation of purified and oil recovery technique class.
Background technology:
Gas injection is the important channel of improving oil recovery.Under different injecting gas and different reservoir condition, gas and crude oil can form mixed phase or non-mixed phase state, by reduce interfacial tension, reduce viscosity of crude, recovery or keep effects such as reservoir pressure, improve oil recovery.Because hydrocarbon gas such as natural gas have some characteristic of oil reservoir crude oil, when injecting, self can not injure oil reservoir, and under low relatively pressure, just can reach mixed phase, perhaps dynamic mixed phase in displacement process, hydrocarbon gas oil recoveries such as natural gas injection have obtained effect preferably.But along with the rise of hydrocarbon gas prices such as natural gas, hydrocarbon gas such as natural gas injection have been subjected to the restriction of economic factor to a certain extent, have therefore accelerated to annotate the particularly research of carbon dioxide injection, nitrogen technology of other gases.In viscous crude heat extraction by steam injection process; main component in the flue gas that injection boiler produces is carbon dioxide and nitrogen; experimental study shows; utilize steam heating boiler and supporting flue gas recycling equipment to combine " stove three is annotated " (steam, CO2, N2); can obtain good effect of increasing production, and help environmental protection.Yet because each side, at present, injecting CO 2, N2 recover the oil and also just are in the single technology stage of experimental study in advance, do not form ripe supporting technology and equipment as yet.
Summary of the invention:
The object of the present invention is to provide a kind of can the reclaiming clean boiler flue and together inject the boiler flue reclaiming clean-up pouring oil production device of oil mining viscous crude with steam.
The present invention realizes like this.This device is made up of boiler, high-pressure hydraulic pump, scrubbing tower, water distributing can, compressor, cooler, clean-up bed, drying bed, degasifier, supercharger and blending tank, boiler is connected with high-pressure hydraulic pump by pipeline, and the top is connected with blending tank with scrubbing tower by pipeline respectively; Scrubbing tower is connected with water distributing can by pipeline, and water distributing can is connected with cooler by pipeline, is provided with compressor therebetween; Cooler is connected with water distributing can by pipeline, and water distributing can is connected with clean-up bed by pipeline; Clean-up bed, drying bed, degasifier are connected by pipeline successively, and degasifier is connected with blending tank with pipeline by supercharger.During work, boiler for producing steam, flue gas is divided water through scrubbing tower and water distributing can washing, and after compressed machine, cooler, water distributing can compression cooling divide water again, enter the clean-up bed desulphurization denitration, again through obtaining the gaseous mixture of carbon dioxide and nitrogen after drying bed, degasifier drying and dehydrating, the absorption deoxidation, through entering blending tank after the supercharger supercharging allotment, mix mutually therein with steam of supplying with by boiler for producing and chemical agent, then by and blending tank and heavy oil wells between pipeline inject into well, in order to increase crude output.
The present invention forms a complete and comprehensive system for collecting real estate fees, and is reasonable in design, practical, utilizes that it can utilize boiler flue to obtain carbon dioxide in the boiler for producing steam heavy oil heat production, nitrogen mixture injects into well, and obtains the good result of incremental oil production and environmental protection.
