Modified well cementation cement slurry as well as preparation method and application thereof
The invention relates to modified well cementation cement slurry as well as a preparation method and application thereof. The modified well cementation cement slurry comprises cement and modified resin emulsion capable of being cured in a single-component mode. Wherein the modified resin emulsion is emulsion obtained by demulsifying and modifying organic silicon high-temperature-resistant resin; the mass of the modified resin emulsion accounts for 2-10% of the mass of the cement. The technical problem to be solved by the invention is how to provide the modified well cementation cement slurry, so that the modified well cementation cement slurry does not need to use a batch mixing pry for double-component blending of resin and a curing agent during site construction, and the construction operation is simple; moreover, by using the modified well cementation cement paste for well cementation, the cementation strength of set cement and two interfaces can be improved, and meanwhile, the modified well cementation cement paste is more beneficial to market popularization due to small addition amount and low material cost.
本发明是关于一种改性固井水泥浆及其制备方法和应用。所述改性固井水泥浆包括水泥和可单组份固化的改性树脂乳液；其中，所述改性树脂乳液为有机硅类抗高温树脂反乳化改性的乳液；所述改性树脂乳液的质量占水泥质量的2～10％。本发明所要解决的技术问题是如何提供一种改性固井水泥浆，使其在现场施工时无需使用批混撬进行树脂和固化剂的双组份调配，施工操作简单；且，使用所述改性固井水泥浆固井既可提高水泥石与两界面的胶结强度，同时因其添加量较小，材料成本低，从而更加有利于市场推广。
