摘　　要：川西须家河组二段气藏具有超深、超高压、超致密的特点,埋深超过4 500 m,岩石坚硬致密、研磨性强、可钻性差,在该地层钻井施工时普遍存在单只钻头进尺少、机械钻速低、起下钻频繁、纯钻时间利用率低、钻井周期长等问题。通过引进涡轮钻井新技术,优选适于该地层的高速涡轮钻具和与之相匹配的孕镶金刚石钻头,应用于3口井中,提速效果明显。West Sichuan Xujiahe Formation 2 has the characteristics of super deep,super high voltage,and super dense.The depth of the well is over 4 500m.The rock is very hard and dense,so it＇s difficult to drill it.When drilling we can meet many problems such as driving less,slow drilling speed,tripping frequently,low drilling time availability and long drilling cycle.Through using turbine drilling technology,selecting suitable drilling tools and bits,the drilling speed can be improved.
