Following presenting the hypothesis of the gas , liquid and
adsorption three phases equilibrium in the porous media , the
phase equilibrium calculation thermodynamic model of gas ,liquid
and adsorption three phases is set up in this paper by using the
Flory Hugging vacancy solution model of gas adsorption. In
simulating the constant volume depletion experiment ,the variety
and difference of high pressure physical parameters are
investigated and the research conclusion is educed respectively
for existing or non-existing the porous media ,considering or non-
considering the capillary pressure , and being or non-being the
adsorption phenomena action. After interpreting the rationality of
the research conclusion , an important technology point for
instructing the exploitation mode of the gas condensate reservoir is
presented in the end of this paper.
