    本文通过分析油井水泥石在酸性气体条件下的腐蚀动力学，提出了油井水泥石的孔隙率是影响其抗酸性气体腐蚀的重要因素，并通过实验发现在油井水泥浆中添加5%偏高岭土可以改善水泥石的孔隙率和抗酸性气体腐蚀性能。

    The corrosion kinetics of acid-gas-expose d oilwellcementissimulated,demonstrating that porosity played a key role in the acid-resistant capability. Further,with the dopant of 5 wt.%of metakaolin,the microstructure and porosity of oil well cement is optimized, the acid-resistant capability of oil wellcement slurry at high temperature is promoted.
