Abstract: The analyses of cause, mechanism and diagnosis method arising from formation pollution were made. The principle, empirical method and fuzzy comprehensive identification method for selecting acidizing well were proposed. A mathematical model for calculating formation statics parameters and predicting acidizing effect with performance parameter was developed. Practical example proved that there is an average relative error of 5.6% between predicted and actual daily injection rate.
