Abstract: To the characterized carrying liquid and liquid holdup of foaming agent in condensate gas field, we have analyzed foam static performance of foaming agent LH1 and several daily domestic foaming agents based on resisting hightemperature performance, resisting high total salinity, resisting high condensed oil. We also have carried foam dynamic performance of foaming agent LH1 and foaming agent UT11C based on liquid holdup and carry liquid. Optimize selecting foaming agent LH1 according to bubble performance, steady bubble performance, liquid holdup and carrying liquid. Design construction scheme of condensate gas well about foaming agent LH1 and carry out field test. Field application indicates that foaming agent LH1 has a good application in condensate gas well.

Key words: condensate gas well, foaming agent LH1, field test, foam static performance
