据中国石油集团工程技术研究院企业首席专家于永金介绍，超过9000米的特深地层，存在着200℃以上 的超高温环境，水泥浆犹如在"热闷罐"中被蒸煮，传统固井材料在此环境下会迅速失效，水泥浆体难以 稳定，固结后的水泥石强度也会严重衰退，这直接影响着超深特深油气井的使用寿命与安全生产。 来源：科技日报 科技日报记者 马爱平 通讯员 夏修建 翟显治 记者27日从中国石油集团工程技术研究院有限公司获悉，该院成功研发出抗240℃超高温固井水泥浆技 术。该技术在我国首口万米科探井——深地塔科1井中经受住极端考验，为万米级深地勘探提供了关键 技术支撑。 为攻克这一难题，研发团队从分子结构设计源头进行颠覆性创新，研发出四大核心材料，构建了新技术 体系。 "其中，核心材料缓凝剂可实现万米井下水泥固化时间的精准调控；降失水剂可形成高效锁水屏障；悬 浮稳定剂可在浆体内构筑三维网络，抵御水泥沉降风险；强度衰退抑制剂则从微观层面强化水泥石长期 强度，使其在240℃高温下长期强度不衰退。这四项材料协同发力，使水泥浆整体耐温能力实现了从 200℃到240℃的跨越。"于永金说。 截至目前，该技术在塔里木、四川、准噶尔等七大盆地6000米以深的超 ...
