| [摘 要]在分析高温盐水钻井液面临主要问题的基础上，对国内外抗高温、抗污染钻井液处理剂及钻井液体系的研究与应用情况进行了介绍。深井、超深井钻探中会面临各种复杂情况，因此对钻井液抗温、抗污染能力的要求也越来越高，主要技术难点是高温高压及高污染条件下钻井液流变性、滤失量、腐蚀性的控制。耐260℃以上抗高温、抗盐处理剂及体系，耐高温钻井液测试仪器是未来抗高温钻井液发展的方向。 |

| Abstract: This paper introduces the worldwide application and research status of the drilling fluid additives with high-temperature and pollution resistance and drilling fluid systems based on the analysis on their crucial issues. It require increasingly high capacity of temperature resistance and antipollution to address the various down-hole problems encountered in the deep well and ultra-deep well drilling. The main technical difficulties include keeping their rheology, filtration loss and corrosion at a proper level. Drilling fluid systems possessing better temperature- and salt resistance against temperature 260 ℃ and relevant apparatus are the very direction of high temperature drilling fluid. |
