Abstract: In this Paper,thin section and scaning electron microscopic analyses have been used tostudying the change of the mineral composition and the pore structure of the rock samples af-ter acid treatment.The test results show that acid ssolution and acid sensitivity is morecomplex than expected.This method reveals details of mechanisms of the acid reaction whichis used to optimize acidizing stimulation treatments.
