High-temperature-resistant tough oil well cement admixture and preparation method thereof
The invention discloses a high-temperature-resistant tough oil well cement admixture and a preparation method thereof, and relates to the technical field of oil-gas field development well cementation materials. The high-temperature-resistant tough oil well cement admixture is prepared from the following raw materials in percentage by weight: 60-70% of a high-temperature strength stabilizing material; 20% of a high-temperature strength reinforcing material; 10%-20% of a high-temperature toughening material; the high-temperature strength reinforcing material is a mixture formed by mixing silicon nitride and organic silicon resin micro powder according to a ratio of 1: 1 or 1.5: 1; the high-temperature toughening material is polyether-ether-ketone resin. The high-temperature-resistant tough oil well cement admixture provided by the invention has the characteristics of high-temperature strength decline resistance and toughening, and the admixture is green, environment-friendly and low in cost.
本发明公开了一种耐高温韧性油井水泥外掺料及其制备方法，涉及油气田开发固井材料技术领域。本发明的耐高温韧性油井水泥外掺料按重量百分比计由以下原料组成：高温强度稳定材料60%～70%；高温强度增强材料20%；高温增韧材料10%～20%；所述高温强度增强材料为氮化硅和有机硅树脂微粉按照1:1或1.5:1的比例混合而成的混合物；所述高温增韧材料为聚醚醚酮树脂。本发明的抗高温韧性油井水泥外掺料，具有抗高温强度衰退及增韧的特点，且外掺料本身绿色环保，成本低。
