摘要：

The gas-mobility reduction capability of sodium dodecylbenzene sulfonate foams was studied in sandpacks as a function of temperature at different surfactant concentrations and gas/liquid ratios. Increasing the temperature decreased the gas mobility at a given surfactant concentration and gas/liquid ratio. At any given temperature, the gas-mobility reduction was not increased beyond a certain limit with increasing surfactant concentration. While increasing the gas/liquid ratio improved the gas-mobility reduction at 20 degrees C, at higher temperatures the reduction capability decreased after reaching a maximum at a gas/liquid ratio of 9. All the foams became weak at temperatures of 150 degrees C and higher.
