The invention relates to the technical field of oil field well repair, in particular to a plugging cement paste system suitable for petroleum well repair of strata in Yayaozu. The cement paste systemconsists of dry powder and water. The dry powder comprises the following components in parts by mass: 100 parts of silicate superfine cement dry powder, 30 parts of G-grade silicate cement dry powder,10 parts of silicon powder, 0.6 part of flexibilizer dry powder, 0.6 part of expanding agent dry powder and 0.5 part of carbon fiber dry powder; the dry powder and water are blended into a slurry product with the density of 1.89 g/cm <3>. The plugging cement paste system is high in binding power, good in impact resistance, high in strength, good in performance, beneficial to on-site constructionand good in plugging effect; and the pressure test of a plugged well section can meet design requirements after plug drilling.
本发明涉及油田修井技术领域，特别涉及一种适用于姚家组地层石油修井用封堵水泥浆体系。该水泥浆体系由干粉剂和水组成，干粉剂的各组成成分及其质量份数为：硅酸盐超细水泥干粉100份，G级硅酸盐水泥干粉30份，硅粉10份，增韧剂干粉0.6份，膨胀剂干粉0.6份，碳纤维干粉0.5份；上述干粉剂与水调配成密度为1.89克/立方厘米的浆体形成本产品。本发明实现了粘结力强，抗冲击性好，强度高，性能良好利于现场施工，封堵效果好，钻塞后对封堵井段试压能够达到设计要求。
