Abstract
Saturation index(SI) is an important parameter to describe the water-rock interaction state,while complex has a significant influence on the state.It is possible to improve the accuracy of SI model by correctly evaluating the content of complex.According to the basic theory of chemical thermodynamics,a FORTRAN code was designed to calculate SI value for modifying solution method of saturation index model.It is proved that this model has better stabilization and precision.
