| 摘 要： | 阿北1井四开井段地层倾角大、构造角度和倾向变化较大,采用大钟摆钻具组合和轻压吊打等措施,纠斜控斜效果不明显。为严格控制井身质量,在四开井段采用171.5 mm VTK垂直钻井系统控制井斜钻进,共计入井11次,总进尺504.92 m,平均机械钻速1.23 m/h,最大井斜2.09°,最小井斜0.11°,不仅达到了纠斜和控斜钻进的目的,同时还提高了机械钻速。

| Abstract: | The fourth spud section formation in Well 1 of Abei has a large inclination with a great variation of tectonic angle and inclination.Adoption of the measures including large pendulum assembly,light compression and bit-easing cannot achieve a remarkable effect of hole straightening and control.To control the quality of well bore strictly,the 171.5 mm VTK vertical drilling system was adopted in the fourth thud section to achieve well deviation control drilling.The 11 hole entries were conducted.The total foot... |
