Well cementation cement slurry composition, well cementation cement slurry system and preparation method and application of well cementation cement slurry composition and well cementation cement slurry system
The invention relates to a well cementation cement slurry composition, a well cementation cement slurry system as well as a preparation method and application of the well cementation cement slurry composition and the well cementation cement slurry system. The composition comprises the following components in parts by weight: 100 parts of a main material, 2-5 parts of a performance optimizing agent, 0.1-1 part of a coagulant, 0.1-2 parts of a fluid loss agent and 42-45 parts of water, the main material is composed of fine cement and a lightening agent, the lightening agent is nano silicon carbide micro powder, and the mass ratio of the fine cement to the nano silicon carbide micro powder is 95: 5-40: 60. The well cementation cement slurry system is prepared from the well cementation cement slurry composition. The density of the cement paste can be changed by adjusting the content of the nano silicon carbide according to field practice, the adjustable range is 1.90-1.21 g/cm < 3 >, and the performance indexes of traditional high-density cement paste can be achieved.
本发明涉及一种固井水泥浆组合物、固井水泥浆体系及其制备方法与应用，所述组合物包含：100重量份主料、2‑5重量份性能优化剂、0.1‑1重量份促凝剂、0.1‑2重量份降失水剂以及42‑45重量份水；所述主料由细水泥和减轻剂组成，所述减轻剂为纳米碳化硅微粉，所述细水泥与纳米碳化硅微粉的质量比为95:5‑40:60。该固井水泥浆体系由该固井水泥浆组合物制备得到。该水泥浆密度可根据现场实际，通过调节纳米碳化硅的含量来实现体系密度变化，可调范围为1.90‑1.21g/cm3，均可达到传统高密度水泥浆的性能指标。
