Abstract:

Big error may occur in using the productivity analysis of single phase gas well for condensate well. According to the steady state theory of the condensate gas reservoir, the productivity equation of gas-liquid multiphase flow was run. On the basis of comparing various productivity calculation formulas,the authors put forward the productivity calculation method for the horizontal well of condensate gas reservoir, which proves a high accurate rate in the cases.

Key words: Songliao Basin, Putaohua Formation, fine exploration, lithologic reservoirs, reservoir inversion
