EFFECT OF POROUS MEDIUM ADSORPTION ON CONDENSATE-GAS PHASE EQUILIBRIUM

Du Jianfen,Li Shilun and Sunlei(Southwest Petroleum Institute).  
The condensate gas phase equilibrium process takes place in the porous media of deep strata.Owing to their giant specific area,the porous media are of a relatively strong adsorption capacity and the fluid exists as two states,i.e.adsorption state and free state.Based on the conventional phase equilibrium analysis and by use of the theory of gas adsorption,a mathematical model of the effect of the mixed gas,adsorbed on the surface of porous media under formation conditions,on the phase equilibrium is set up,a phase equilibrium calculation method of considering porous medium adsorption is proposed and through an example calculation the effect of the porous medium adsorption on the phase equilibrium is analyzed.It is concluded that the adsorption of porous media should be considered in the percolation of the condensate and gas;heavy hydrocarbon component is prior adsorbed and the desorption heavy hydrocarbon component is more than the desorption light one along with pressure decrease;the adsorbance decreases along with temperature increase;and the lower the reservoir porosity,the more the adsorbed gas.
