Raw material composition of geopolymer slurry, geopolymer slurry as well as preparation method and application of geopolymer slurry
The invention relates to the field of oil and gas well cementation, and discloses a raw material composition of geopolymer slurry, the geopolymer slurry and a preparation method and application of the geopolymer slurry, and the composition comprises a modified SiO2-Al2O3 nano composite material, metakaolin and an activating agent; wherein the modified SiO2-Al2O3 nano composite material is prepared from SiO2-Al2O3 nano composite particles and hydrophobic functional groups attached to the surfaces of the particles. According to the invention, the modified SiO2-Al2O3 nano composite material is introduced into the geopolymer slurry for the first time, on one hand, the nano Si-Al2O3 can play a role in blocking gaps, and on the other hand, the nano Si-Al2O3 can react with the geopolymer to generate additional aluminosilicate hydrate (CASH) and sodium aluminosilicate hydrate (NASH); the compressive strength, bending strength and elastic modulus of the geopolymer slurry are increased, and pores or cracks are filled to form a dense and robust geopolymer.
本发明涉及油气井固井领域，公开了一种地质聚合物浆料的原料组合物、地质聚合物浆料及其制备方法与应用，所述组合物包含改性SiO2‑Al2O3纳米复合材料、偏高岭土、激活剂；其中，所述改性SiO2‑Al2O3纳米复合材料包括：SiO2‑Al2O3纳米复合颗粒和在颗粒的表面附着的疏水性官能团。在本发明中，所述地质聚合物浆料中首次引入改性SiO2‑Al2O3纳米复合材料，一方面纳米Si‑Al2O3可以起到堵塞空隙的作用，另一方面纳米Si‑Al2O3可以与地质聚合物反应，生成额外的铝硅酸盐水合物(CASH)和铝硅酸钠水合物(NASH)，使得地质聚合物浆料的抗压强度、抗弯强度和弹性模量增加，并填充孔隙或裂缝以形成致密而坚固的地质聚合物。
