The CO2 is stimulating factors and bubbling gas, the ammonia water is a defoaming liquid, the bubbling liquid is prepared from a bubbling agent and deionized water, the bubbling agent accounts for 0.1-1% by mass of the bubbling liquid, and the bubbling agent is erucyl amide propyl-N,N-dimethyl tertiary amine or oleic amide propyl-N,N-dimethyl tertiary amine. The foam system is simple in component and sensitive in foam switching property, and still has relatively good foaming property and switching property in a high-temperature and high-pressure environment.
