| 中文摘要:随着能源消费持续升高，常规资源无法满足日常需求，进行深井钻探显得尤为重要。然而，井底深部高温带来的钻井液粘度增加、流变性变差等问题，致使降粘剂成为不可缺少的钻井液处理剂之一。降粘剂主要通过拆散或阻拦粘土颗粒间形成网架结构，从而达到降低钻井液粘度、改善流变性的目的。结合相关研究文献，综述近十年来国内钻井液降粘剂的研究现状，介绍了3大类降粘剂：合成聚合物类、改性天然材料类、利用工业废料制备降粘剂。针对目前存在的问题，指出未来应从分子结构设计层面研发低成本、环保、适用于高温高盐高密度钻井液的降粘剂，同时注重工业废料的利用，积极与现场应用相结合加快成果转化。近年来，合成聚合物类降粘剂研究量居多、发展最迅速，本文着重介绍了此类降粘剂的发展现状及应用前景。 |

| Abstract:As energy consumption continues to rise， and conventional resources cannot meet daily needs， deep well drilling is particularly important. However， problems such as increased viscosity of drilling fluid， deterioration of rheology caused by high temperature at the bottom of the well have made the high temperature resistant viscosity reducer one of the indispensable drilling fluid treatment agents. To reduce the viscosity of the drilling fluid and improve the rheology， viscosity reducers mainly disassemble or block the formation of the grid structure between clay particles. In reference to the relevant research literature， this paper summarizes the research status of domestic drilling fluid viscosity reducers in the past ten years with emphasis on three types of viscosity reducers： synthetic polymers， modified natural materials， and industrial waste-made viscosity reducers. In view of the current problems， it is pointed out that in the future， low-cost and environment-friendly viscosity reducers suitable for high-temperature， high-salt and high-density drilling fluids should be developed at the molecular structure design level. At the same time， it pays attention to the utilization of industrial waste and the speeding up of the technology transformation through field applications. In recent years， synthetic polymer viscosity reducers have been studied mostly and developed the fastest. This article focuses on the development status and prospects of this type of viscosity reducer. |
