Abstract This study proposes potential replacement for the Portland-based cement, which is a common sealant used in deep high-temperature geothermal wellbore completions. The experimental laboratory studies were focussed on alkali-activated aluminosilicates. It was proven, that the so-called, geopolymer-based sealing systems exhibit high compressive and flexural strength at elevated temperatures, good resistance towards thermal cyclic loading, high ductility, acid insensitivity, and improved water permeability. Additionally, alkali-activated aluminosilicate sealing systems are economically feasible and their CO2 emission, during the manufacturing process, is significantly lower in comparison with the conventional Portland-based cement types, making them an environmentally friendly option for deep wellbore completions in unconventional high-temperature geothermal systems.

用于深部高温井应用的碱活化铝硅酸盐密封系统

摘要 本研究提出了硅酸盐水泥的潜在替代品,波特兰水泥是深部高温地热井筒完井中常用的密封剂。实验实验室研究集中在碱活化的铝硅酸盐上。事实证明,所谓的基于地质聚合物的密封系统在高温下表现出高压缩和弯曲强度、良好的抗热循环载荷、高延展性、酸不敏感性和改善的透水性。此外,碱活化铝硅酸盐密封系统在经济上是可行的,与传统的波特兰水泥类型相比,它们在制造过程中的二氧化碳排放量显着降低,
