Abstract | The in-situ laboratory measurement of pH in a granite-hot water reaction system has been undertaken under flowing conditions. The calculation of fluid pH and multi-component chemical equilibria in the granite-hot water reaction system was made, using the calculation program SOLVEQ92. In this study, the chemical equilibrium relationship of granite and hot water interaction was also deduced using the some program. The measurement of in-situ pH in the granite-hot water reaction system was undertaken in the temperature and pressure range of 100-250°C and 20 MPa respectively. The in-situ pH value shows good agreement with the pH calculation value with regard to multi-component chemical equilibria. As a result of this work, it is reasonable to suggest that the pH of reservoir fluids in geothermal system can be readily estimated by use of the SOLVEQ92 calculation program, which provides a 'calculated' pH value. |
