Reinforcing material for oil and gas well cementing cement as well as preparation method and application of reinforcing material
The invention discloses a reinforcing material for well cementation cement for oil and gas wells and a preparation method and application of the reinforcing material, and relates to the technical field of well cementation materials for oil and gas development in deep high-temperature stratums. 16-20% of rare earth tailings; 8-12% of magnesium slag; 5-10% of purple clay; 4-6% of apatite; 3-5% of graphite; meanwhile, the invention discloses a preparation method of the reinforcing material, the high-temperature mechanical property, durability and stability of set cement can be obviously improved by adopting the reinforcing material, and the reinforcing material can be applied to preparation of oil and gas well cementing cement slurry for a deep high-temperature stratum environment with the temperature of 230 DEG C. Meanwhile, the raw materials of the reinforcing material are easy to obtain, part of industrial waste can be consumed, and the material cost is low.
本发明公开了一种油气井固井水泥用增强材料及其制备方法、应用，涉及深部高温地层中油气开发固井材料技术领域，增强材料按重量百分比计包括下述组分：石英粉50‑60%；稀土尾矿16‑20%；镁渣8‑12%；紫砂土5‑10%；磷灰石4‑6%；石墨3‑5%；短切碳纤维1%，同时公开了增强材料的制备方法，采用该增强材料能明显改善水泥石的高温力学性能、耐久性、稳定性，可应用于制备深部230℃的高温地层环境用油气井固井水泥浆中。同时，该增强材料的原料易得，还可消耗部分工业废料，材料成本较低。
