Abstract
Foam drainage is the flow of liquid through the interstitial spaces between bubbles driven by capillarity and gravity and resisted by viscous damping. The so-called foam drainage gas recovery technology is a technique traditionally used to mitigate the serious bottom-hole liquid loading in the middle and late stages of gas well
production. In this context, determining the optimal concentration of the bubble drainage agent is generally crucial for the proper application of this method. In this study, a combination of indoor experiments and theoretical
analysis have been used to determine the pressure drop related to the foam-carrying capacity in a representative
gas field. Dynamic and static experiments were designed with a bubble drainage agent concentration varying in
the range 0.3%–0.6%. Using the field formation water data, the optimal soaking agent concentration was obtained
and pressure drop test experiments on the foam carrying capacity were conducted accordingly. These tests have
revealed that the optimal foam displacement agent concentration is 0.5%, and the foam quality at the optimum
concentration is between 0.78–0.98. A theoretical method for calculating the pressure drop at the optimum soakaway concentration based on experimental data has also been introduced. The error of the proposed method is
within 15% compared to the experimental measured value, demonstrating that it is highly accurate and simple.
