Geopolymer raw material composition, geopolymer precursor slurry, application and high-temperature well cementation method
The invention relates to the field of geopolymers, and discloses a geopolymer raw material composition, geopolymer precursor slurry, application and a high-temperature well cementation method. The geopolymer raw material composition comprises a silicon-aluminum raw material, a surface modifier, an activating agent, a dispersing agent, a cosolvent, a reinforcing agent and a defoaming agent, the surface modifier is a phthalic ester coupling agent. The composition can be used for preparing geopolymer precursor slurry with delayed curing performance, the curing time under the condition of 60-100 DEG C is longer than 120 min, the fluidity is larger than 18 cm, the compressive strength of the geopolymer after curing for 1 day is larger than 7 MPa, and the compressive strength of the geopolymer after curing for 3 days is larger than 14 MPa. The curing time of the geopolymer precursor slurry can be prolonged under the underground high-temperature condition of an oil-gas well, and the requirements of well cementation construction are met.
