For liquid-loading gas wells，applications of high-performance foaming complexes are key to successful foam-assisted removal of water accumulating in gas wells. Therefore，in this paper，we developed a gemini cationic surfactant （CAGB） and combined it with sodium cocoyl glycinate （SCG） and a short-chain fluorocarbon surfactant FS-50 to form an excellent ternary foam drainage formulation tolerant of salts and gas condensate. Experimental results showed that with the CAGB/SCG/FS-50 molar ratio of 4∶16∶5 and a total concentration of 25 mmol/L，the foam volume and half-life time were optimized up to 455 mL and 20.45 min，respectively. After adding rhamnose，the foam volume and half-life were 405 mL and 74.09 min，respectively. The liquid carrying tests showed that a certain amount of condensate and methanol can enhance the liquid carrying performance of the foaming formulation. The liquid-carrying rate reached 45.94% in the case of the condensate content of 50%，and the foam formulation could withstand up to 60% condensate. Methanol also promoted the liquid-carrying performance. When the methanol content was 20%，the liquid-carrying rate could be increased to 44.69% and it remained high even at the methanol content of 60%. The addition of rhamnose allowed the ternary foaming formulation to maintain stable liquid-carrying capability at a salinity of 410 g/L，with a liquid-carrying rate of 32.35%. Elevated temperature is in favor of improving the liquid-carrying capability of the ternary foaming formulation，and the liquid-carry rate was high up to 69.11% at 90 ºC. Finally，surface tension tests and foam morphological observations also confirmed the synergistic effect of the components of the foaming formulation.
