Impact-resistant well cementation cement slurry system as well as preparation method and application thereof
The invention discloses an impact-resistant well cementation cement slurry system as well as a preparation method and application thereof. The impact-resistant well cementation cement slurry system comprises cement, aggregate, a nano active material, a toughening material I, a toughening material II, an early strength agent, a coagulation accelerator, a water reducing agent and water, the toughening material I is selected from at least one of polypropylene fiber, polyvinyl alcohol fiber and polyacrylonitrile fiber; the toughening material II is selected from at least one of calcium carbonate whiskers, magnesium sulfate whiskers and calcium sulfate whiskers. The well cementation cement slurry system is good in compatibility with various additives and stable in performance, set cement obtained after setting and hardening has high impact toughness and strength, can bear shaft internal pressure, external extrusion, drilling impact load and the like after well cementation of shallow surface strata in oil and gas wells, and can be used for well cementation of oil and gas wells. Functional requirements of oil and gas well shallow surface layer non-metal casing pipe well cementation are met, well cementation cost is effectively reduced, and cost reduction and efficiency improvement of oil and gas development are achieved.
本发明公开了一种抗冲击固井水泥浆体系及其制备方法和应用。本发明的抗冲击固井水泥浆体系,包含有水泥、骨料、纳米活性材料、增韧材料I、增韧材料II、早强剂、促凝剂、减水剂和水；所述增韧材料I选自聚丙烯纤维、聚乙烯醇纤维、聚丙烯腈纤维中的至少一种；所述增韧材料II选自碳酸钙晶须、硫酸镁晶须、硫酸钙晶须中的至少一种。所述固井水泥浆体系与各种外加剂之间的配伍性较好，且性能稳定，经凝结硬化后所得到的水泥石，具有高冲击韧性和强度，可承受油气井中浅表层地层固井后井筒内压、外挤和钻进冲击荷载等，满足油气井浅表层非金属套管固井的功能要求，有效降低固井成本，实现油气开发的降本增效。
