摘要
用薄片和扫描电镜观察分析储层岩石酸化后矿物成分和孔隙结构变化的酸化反应。试验结果表明，砂岩的酸蚀与酸敏比我们预期的要复杂得多，该法揭示出酸化反应的某些细节，有助于深入了解酸化反应机理和设计适合的酸化方案。
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.
