摘要： 吉木萨尔凹陷二叠系致密油藏钻井面临地层可钻性差、机械钻速慢、井眼稳定性差、阻卡多等诸多难题。针对不同的地质情况，2012年通过应用高效PDC钻头、自激振荡旋冲钻井工具、扭力冲击器等先进的提速工具，使二叠系机械钻速稳步提高，事故复杂时率下降，取得了良好的效果。

Abstract: The tight oil reservoir drilling in Jimsar sag of Permian in Junggar basin is faced with several problems such as poor and slow rate of penetration, poor wellbore stability, serious blockage during tripping, etc. According to different geological conditions, a series of new drilling technologies were used to improve drilling speed in this area in 2012, including high?efficiency PDC bit, self?oscillating rotary percussion drilling tools, Torkbuster, etc, which allowed the drilling penetration rate to be improved and the complex damage rate to be decreased significantly or obviously
