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
