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 with steam with the boiler flue reclaiming clean-up pouring oil production device that injects the oil mining viscous crude.
The present invention realizes like this.This device is made up of boiler, high-pressure hydraulic pump, scrubbing tower, air-introduced machine, absorption tower, knockout drum, heat exchanger, regenerator, reboiler, steam oven, water distributing can, carbon-dioxide gas compressor, clarifier, nitrogen compressor, drying bed, adsorbent bed, carbon dioxide supercharger, nitrogen supercharging machine, 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 clarifier by pipeline, is provided with carbon-dioxide gas compressor therebetween; Clarifier is connected with blending tank by pipeline, is provided with the carbon dioxide supercharger therebetween; Nitrogen compressor links to each other with drying bed by pipeline, and drying bed links to each other with adsorbent bed by pipeline, and adsorbent bed links to each other with oil well casing by pipeline, is provided with the nitrogen supercharging machine therebetween.During work, the steam of boiler for producing can directly inject into well, and flue gas can be produced 98% carbon dioxide gas through scrubbing tower, absorption tower, regenerator washing, absorption, regeneration.Flue tail gas can be produced 96% nitrogen again after overcompression, drying, absorption.Like this, the three kinds of gases of water vapour, gaseous carbon dioxide, nitrogen that obtained step by step by boiler inject oil well by supercharging allotment back, can reach the purpose that increases crude output and environmental protection.
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 viscous crude, nitrogen mixture injects into well, and obtains the good result of incremental oil production and environmental protection.
