Retarding type high-strength cement additive for oil field well cementation as well as preparation method and application of retarding type high-strength cement additive
The invention discloses a retarding type high-strength cement additive for oil field well cementation and a preparation method and application thereof, and belongs to the technical field of oil field well cementation cement additives. The retarding type high-strength cement additive for oil field well cementation is mainly prepared from the following raw materials: 30 to 45 parts of fly ash floating beads, 10 to 18 parts of quartz sand, 8 to 12 parts of porous ceramic balls, 5 to 15 parts of a retarder composition and 1 to 5 parts of rubber particles, wherein the retarder composition is mainly prepared by compounding lignosulfonate, citric acid and polyethylene glycol 400 according to the weight ratio of 1 to (2 to 3) to (7 to 10). According to the retarding type high-strength cement additive for oil field well cementation and the preparation method of the retarding type high-strength cement additive, the preparation method is simple, the fluidity is good in the cement slurry preparation process, dispersion is easy, the retarding effect is good, the cement thickening time can be delayed till the cement slurry is suitable for well cementation construction, the compressive strength, tensile strength and breaking strength of cement stone are greatly improved, gas spurting is prevented, and the service life of the cement slurry is prolonged. The well cementation quality is improved.
本发明公开了一种缓凝型油田固井用高强度水泥添加剂及其制备方法和应用，属于油田固井水泥添加剂技术领域。本发明的缓凝型油田固井用高强度水泥添加剂主要由如下原料组成：粉煤灰漂珠30‑45份、石英砂10‑18份、多孔陶瓷球8‑12份、缓凝剂组合物5‑15份和橡胶颗粒1‑5份，缓凝剂组合物主要由木质磺酸盐、柠檬酸、聚乙二醇400按照重量比1：(2‑3)：(7‑10)复配而成。本发明的缓凝型油田固井用高强度水泥添加剂及其制备方法，其制备方法简单，在水泥浆液制备过程中流动性好，易于分散，缓凝效果佳，能够将水泥稠化时间延后至适于固井施工，极大提高水泥石的抗压强度、抗拉强度和抗折强度，防止气蹿，提高固井质量。
