High-strength oil field well cementation cement additive as well as preparation method and application thereof
The invention discloses a high-strength oil field well cementation cement additive as well as a preparation method and application thereof, and relates to the technical field of cement additives. The high-strength oil field well cementation cement additive mainly comprises the following raw materials in parts by weight: 20-30 parts of modified fly ash floating beads, 10-20 parts of microcrystalline cellulose, 1-5 parts of sodium lignin sulfonate, 15-20 parts of silicone oil, 5-10 parts of quartz sand and 1-5 parts of rubber particles. The preparation method is simple, the prepared cement additive has long thickening time and good rheological property after being made into cement paste, longer time is reserved for underground construction, the good construction effect is ensured, the cement additive has high compressive strength, tensile strength and breaking strength after being made into set cement, and the cement additive has good application prospects. And gas channeling can be effectively prevented, the well cementation quality is improved, and high use value is achieved.
本发明公开了一种高强度油田固井水泥添加剂及其制备方法和应用,涉及水泥添加剂技术领域,本发明高强度油田固井水泥添加剂主要由如下重量份数的原料组成:改性粉煤灰漂珠20‑30份、微晶纤维素10‑20份、木质素磺酸钠1‑5份、硅油15‑20份、石英砂5‑10份和橡胶颗粒1‑5份。本发明制备方法简单,制备的水泥添加剂在制成水泥浆以后具较长的稠化时间和良好的流变性能,为井下施工预留了更长的时间,确保施工效果好,水泥添加剂在制成水泥石以后,具有较强的抗压强度、抗拉强度和抗折强度,能够有效防止气窜,提高了固井质量,具有很强的使用价值。
