摘　　要：分析了塔河油田上部砂泥岩易缩径地层、下部易扩径的三叠系石炭系硬脆性地层的地质特征及钻井技术难点,针对长裸眼井钻遇不同地层所出现的不同问题,采用了不同的钻井液体系并采取了不同的维护处理措施,成功解决了塔河油田优快钻井中长裸眼地层的井眼稳定、钻井液性能维护等一系列技术问题,现场应用效果良好。The geological characteristics and drilling challenges involved while drilling particular formations in the Tahe Oilfield arc analyzed, these formations are upper shale prone to he tight hole, lower crisp formations in the Tertiary system and the Carboniferous system. Different downhole potential hazards likely happen while drilling long open hole in above mentioned formations. Therefore, different drilling fluid systems and maintenances are taken, which successfully settle down a series of technical problems including wellbore stability and drilling fluid maintenances while drilling long open hole in the Tahe Oilfield.
