偏高岭土及其对油井水泥性能的影响

Metakaolin and Its Influence on Oil Well Cement Performance

综述了偏高岭土特性及其在水泥混凝土领域中的应用情况,初步研究了偏高岭土对油井水泥性能的影响。结果表明,偏高岭土能显著提高油井水泥的抗压强度,表现出很强的火山灰活性,完全可以作为新一代的油井水泥掺合料。

This paper gives an overview of the properties of the metakaolin and its application in cement and concrete industry. The influences of metakaolin on performance of oil well cement were preliminarily investigated. The study showed that metakaolin remarkably improved the compressive strength of oil well cement and it showed a volcanic ash activity. The metakaolin can therefore be used as a new-generation additive in cement slurry.
