DIRECTIONAL DRILLING TECHNOLOGY FOR SMALL TARGET ZONE WITH MULTIPLE POINTS IN HUZHUANG AREA

    Graphical Abstract
    • Abstract
  • Features small target radius,high deviation,long horizontal displacement and multiple target points,drilling of directional wells of multiple points in small target zone is relatively difficult.Well location selection,hole profile design,well trajectory control and safety operation technology were presented.10 such directional wells were planed in Huzhuang area in Zhongyuan oilfield in recent years,and a set of fast drilling technologies were developed which involves using of combined drilling technology and high efficient PDC bits.
