摘　　要：从材料学角度出发,结合现场实际问题,通过对油井水泥固有缺陷和常用油井水泥外加剂特性的分析,阐述了影响井下水泥环长期封隔质量的3个主要因素,即水泥浆的漏失低返、水泥石的体积收缩和高脆性。在讨论新材料作用机理的基础上,提出了初步的解决方案,并介绍了新材料的现场应用情况。同时文中还就国内油田未来对固井新材料的技术需求进行了预测,并就今后的研究方向提出了建议。From viewpoint of material science, and based on the applying experience, three main factors such as the lower-flow-back of cement slurry, the bulk shrinkage and the high fragility of cement stone, which affect zonal bonding quality of cement sheath, are expatiated through analyzing congenital defect of oil well cement and the properties of additive. On the basis of discussing novel material function mechanism, settled project is put forward primarily and novel material field applications are introduced. The technique requirement of cementing material for domestic oilfield and the future ways of research are proposed.
