Abstract

Abstract:

The stability of foam system is very important in the application of foam flooding and gas reservoir foam drainage agent. The influence of surfactant molecular structure and interface arrangement on the permeability and stability of foam liquid film is of great significance for the construction of highly stable CO₂ foam, but there is no systematic understanding at present. The betaine surfactant with four molecular structures is used as the research object, and the foam phase property evaluation is used as the research method. For the saturated adsorption capacity, foam liquid film permeability, foam stability and other phase properties, the surfactant molecular structure, interface arrangement, CO₂ foam liquid film permeability, foam stability and their correlation experiments are carried out. The results show that when the molecular head groups of surfactants are consistent, the hydrophobic carbon chain length increases, the hydrophobic effect increases, the molecules on the liquid film surface are arranged more closely, the permeability of foam liquid film decreases, and the stability of foam increases. When surfactant molecules have longer hydrophobic carbon chains, the enhanced hydrophobicity leads to a tighter arrangement of the liquid membrane and an increase in adsorption capacity, hindering the permeation behavior of CO₂ gas within the bubble and weakening the foaming ability of the foaming solution. Based on the regression analysis of the parameters obtained from four foaming systems, the correlation coefficient R² between foam life, foam liquid film molecular adsorption capacity and foaming capacity and foam liquid film permeability K is established. The fitting shows that R²>0.90. Therefore, the permeability of foam liquid film K can be used as one of the parameters to evaluate the stability of foam system and provide a reliable evaluation parameter for the screening of highly stable foam system.

Key words: surfactants, molecular structure, foam film permeability, saturated adsorption capacity, foam stability

饱和吸附量	R²=0.91	吸附量越大，表明界面排布越密集，液膜渗透率越低，泡沫稳定性越好
起泡体积	R²=0.96	起泡液中表面活性剂分子碳链长度增加，起泡液的起泡能力增大，但与泡沫的渗透能力并未存在趋势关系
析液半衰期	R²=0.96	泡沫液膜渗透能力制约了泡沫的寿命与液膜稳定性，液膜渗透能力越差，泡沫寿命越久，表明泡沫越稳定
泡沫半衰期	R²=0.98	泡沫液膜渗透能力制约了泡沫的寿命与液膜稳定性，液膜渗透能力越差，泡沫寿命越久，表明泡沫越稳定
