Book excerpt: 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.
