Abstract: Acidization is an important measure of going into production and of stimulation in carbonate oil and gas reservoirs.A successful acidization depends upon the technical level of its job and treatment design. Making the complete and accurate design of acidizing treatment depends on selecting the design parameters.The results from our experimental study on the chemical kinetics of the reaction of acid on reservoir rocks have been partly given out in this paper. By analyzing these results, we have obtained some conclusions that are useful for practical acidizing job and treatment design.
