This study aimed to design multifunctional high-temperature foamed and
non-foamed geothermal well cement composites encompassing the following five
advanced properties, by comparison with two geothermal well cement systems,
Class G/silica flour and/or calcium aluminate phosphate:
1) TS
resistance based on 500℃ or 600℃ heating-25℃ water quenching cycle tests;
2)
compressive toughness;
3)
protection of the CS against brine corrosion;
4)
adherence of the cement to the CS and post-TS bond durability;
5)
reduced acid-scale corrosion and erosion. Furthermore, we experimentally
investigated set-controlling additives and their corresponding set-retarding
chemistry.
