Factors influencing the stability of natural gas foam prepared by alkyl polyglycosides and its decay rules

By using alkyl polyglycoside (APG) as foaming agent and natural gas as gas phase, the natural gas foam system was prepared, and the influence of alkyl chain length, metal cation valence and concentration, and polymer types on the foam stability was studied. By completely observing the volume and time required for the foam drainage liquid under different conditions, a foam drainage kinetics model was established. The drainage rate constant, the...
