Research On Mechanism Of Three Combination Huffing-puffing For Ultra-heavy Oil

To further enhance the development of effective, in ultra-heavy oil blockd reservoir Du-84 and Du-32, the special oil develop company at Liao He oil field adopt surface-active agents+CO₂+steam three-compound-combination huffing-puffing method, which can increase oil/gas ratio in well and improved the production results ,and then achieved good results. For further study for the laws and mechanisms and the impact factorsof three-compound-combination huffing-puffing method, We carry out the topic"Research Mechanism of three combination huffing-puffing for ultra-heavy oil", which provides powerful technical supports for the ultra-heavy oil development at Liao He.This paper study Solubility of solid carbon dioxide in ultra-heavy oil of blockd rese rvoir Du-84 and Du-32 based on a lot of laboratory experiments, and carry out physical simulation experiment to research mechanism of three combination huffing-puffing for ultra-heavy oil,through physical simulation experiment we study the intake volume of Carbon Dioxide,the intake volume of stream , the concentration of surfactant,the rate of stream release and different gas and how they influence the three combination huffing-puffing,and we have studied corrosion and scale deposit for the three combination huffing-puffing.
