摘要: 普通水泥存在固化后体积收缩、脆性大且生产耗能高等问题,而氯氧镁水泥能较好地改善普通油井水泥的弱点,并具有力学强度高、CO2吸附性强、耐温、抗盐卤腐蚀等工程优势,研究氯氧镁水泥在油气井工程中的应用具有重要意义。为此,介绍了氯氧镁水泥基本组成、水化产物及水化反应机理,总结了氯氧镁水泥在油气井固井、储层堵漏、钻井废弃物处理等方面的研究现状,指出了目前研究存在问题及研究方向,并指明了氯氧镁水泥在CCUS、盐膏层固井、深水浅层固井等方面的潜在应用前景。研究成果可为氯氧镁水泥在石油领域的应用与发展提供参考。

Abstract: Conventional cement exhibits issues such as volume shrinkage after curing,high brittleness,and high energy consumption during production.In contrast,magnesium oxychloride cement can effectively mitigate the above weaknesses,and possesses engineering advantages such as high mechanical strength,strong CO2 adsorption,temperature resistance,and resistance to salt-brine corrosion.Investigating the application of magnesium oxychloride cement in oil and gas well engineering is of significant importance.Therefore,this paper introduces the basic composition,hydration products,and hydration reaction mechanism of magnesium oxychloride cement.It summarizes the current research status of magnesium oxychloride cement in oil and gas well cementing,reservoir sealing,and drilling waste disposal.It identifies existing research issues and research directions,and highlights the potential application prospects of magnesium oxychloride cement in CCUS,salt-gypsum layer cementing,and deepwater shallow formation cementing.The research findings can provide a reference for the application and development of magnesium oxychloride cement in the petroleum industry.

Key words: magnesium oxychloride cement, well cementation, sealing, water resistance, compressive strength, CCUS, review
