| Abstract: | The method of using mixture of HF and HCL to treat sandstone formations of remove formation damage near the wellbore is a widely used stimulation treatment. However, how to predict the results of sandstone acidization and select optimal job parameters is still an open question. Using lumped parameter model to calculate the distribution of acid concentration along the formation, this paper presents a set of simple methods available for predicting sandstone acidization by using numerical solution to calculate the acidizing stimulation ratio.This paper also gives out the solution and calculations of some examples. |
