| 摘要: |
| 改性热固性树脂是通过物理共混或者化学交联的方式引入特定元素或官能团形成的具有体型网络结构的高分子材料。优异的耐热耐压性能和力学性能使得热固性树脂及其改性产品在机械、建筑以及民用生活等领域成为不可或缺的基础材料。综述环氧树脂、酚醛树脂、聚氨酯树脂及不饱和聚酯树脂等4种热固性树脂的改性机制及改性后材料特点,结合钻井液相关处理剂研究现状和不同改性热固性树脂性能特点,展望改性热固性树脂在井壁稳定、钻井液降滤失及防漏堵漏领域的应用前景。改性热固性树脂在钻井液领域的研究和应用将推动钻井液处理剂向高性能低成本的方向发展。 |

| Abstract: |
| Modified thermosetting resin is a polymer material with a bulk network structure formed by introducing specific elements or functional groups through physical blending or chemical cross-linking. Excellent heat and pressure resistance, as well as mechanical properties make thermosetting resins and their modified products indispensable basic materials in the fields of machinery, construction and civil life. The modification mechanism and material characteristics of four kinds of thermosetting resins such as epoxy resin, phenolic resin, polyurethane resin and unsaturated polyester resin are reviewed. Combined with the research status of drilling fluid related treatment agents and the performance characteristics of different modified thermosetting resins, the application prospect of modified thermosetting resins in the fields of wellbore stability, drilling fluid filtration reduction and leakage prevention and plugging is prospected. The research and application of modified thermosetting resins in the field of drilling fluids will promote the development of drilling fluid treatment agents towards high performance and low cost. |
