Heat insulation cement paste and preparation method thereof
The invention relates to the technical field of cement paste for well cementation in the field of drilling engineering, in particular to a heat insulation cement paste and a preparation method thereof. The heat insulation cement paste is prepared from cement, a heat insulation material, quartz sand, silica fume, an early strength agent, an expanding agent, an additive and water. The heat insulation cement paste obtained by the invention is stable in performance, low in heat conductivity and small in heat loss, and has stronger heat insulation effect; the difficult problems that when a heavy oil thermal recovery well carries out injecting steam production, heat dissipation of a cement sheath is serious, energy source waste is huge and the production cost is high are solved; meanwhile, by adding the heat insulation material, the heat insulation cement paste has good compressive strength, good heat insulation and corrosion resistance as well as fire and alkali resistance, and can be popularized and applied in the heavy oil thermal recovery well on a large scale.
