摘　　要：本文介绍了一种含HPAM、PMNK和PAC-1的钻井液。室内试验及现场应用证明,该钻井液对页岩的水化膨胀有良好的抑制作用,具有良好的抗盐抗钙性能,能用于较深井段,使用时间长,能提高机械钻速,明显降低钻井成本。A polymer drilling fluid composed of HPAM, PMNK, and PAC-1 is developed for use in East Sichuan region. In Laboratory and field tests and in practical applications, this drilling fluid is shown to strongly inhibit shale hydration and dispersion, be salt-and calcium-tolerent, and work well in deep sections in well bore with long service time. As a result the penetration rate is improved and the drilling cost dramatically reduced, The usage of this drilling fluid is described.
