Large-temperature-difference well cementation cement paste as well as preparation method and application thereof
The invention belongs to the technical field of oil and gas wells, and discloses large-temperature-difference well cementation cement paste as well as a preparation method and application thereof. The cement paste comprises oil well cement, gypsum, red mud, sulphoaluminate cement, silicon powder, water and an auxiliary agent. The large temperature difference adaptive capacity of the cement paste is improved by generating ettringite in the hydration reaction process.
本发明属于油气井技术领域，公开了一种大温差固井水泥浆及制备方法和应用。该水泥浆包括油井水泥、石膏、赤泥、硫铝酸盐水泥、硅粉、水和助剂。本发明通过在水化反应过程中产生钙矾石来改善水泥浆的大温差适应能力。
