| 摘 要： | 钻井液的性质及性能参数对于南极科学钻探有着重要的影响。钻井液除了必须要具备合适的粘度和密度，以满足冷却钻头、平衡孔壁压力、携带冰屑、清洁孔底的要求外，钻井液的性质如导电性、导热性及其腐蚀性对于保证钻具的正常工作、输送孔内信息也有着重要的影响。根据目前已经在南极使用的钻井液类型，分别对6种介质（国产硅油-3cst、KF96硅油-2cst、丁酸乙酯、丁酸丁酯、丁酸戊酯、丙酸丙酯）在不同温度下的电导率、导热系数和对密封件的腐蚀性进行了试验测试，选出了适合南极应用的钻井液类型及在钻具中使用的密封件材质，可供极地钻探选择钻井液类型及钻具设计提供重要的参考。

| Abstract: | Drilling fluid properties and performance parameters have significant influence on Antarctic scientific drilling. Drilling fluids should have appropriate viscosity and density to cool drill bit, balance hole wall pressure, carry ice chips and clean hole bottom; in addition, its properties, such as electrical conductivity, thermal conductivity and corrosion, also have important influence on drilling tools for normal operation and downhole information transmission. According to the types of drilling fluid used in Antarctic, experimental tests were made on the conductivity, thermal conductivity and corrosion on sealing components of 6 kinds of medium DSO-3.0cst, KF96 silicone oil-2.0cst, ethyl butyrate, n-butyl butyrate, n-amyl butyrate and n-propyl propionate respectively under different temperatures, the drilling fluids and sealing materials suitable for Antarctic are selected, which can be important reference for drilling fluid selection and drilling tools design. |
