英文摘要	A mutual solubility model for CO2-CH4-brine systems is constructed in this work as a fundamental research for applications of deep hydrocarbon exploration and production. The model is validated to be accurate for wide ranges of temperature (0-250 degrees C), pressure (1-1500 bar), and salinity (NaCl molality from 0 to more than 6mole/KgW). Combining this model with PHREEQC functionalities, CO2-CH4-brine-carbonate-sulfate equilibrium is calculated. From the calculations, we conclude that, for CO2 CH4-brine-carbonate systems, at deeper positions, magnesium is more likely to be dissolved in aqueous phase and calcite can be more stable than dolomite and, for CO2-CH4-brine-sulfate systems, with a presence of CH (,) sulfate ions are likely to be reduced to S-2-and H2S in gas phase could be released after S-2-saturated in the solution. The hydrocarbon "souring" process could be reproduced from geochemical calculations in this work.
