摘　　要：深井钻进中,随着井深的增加,钻进条件变得更为复杂,钻井效率降低,钻井质量不易保证,井斜问题更加难以控制。俄罗斯地质钻探工程中正在积极使用回转导向系统Роторные управляемые системы--РУС(Rotary Steerable System--RSS),主要是利用井底钻头的造斜作用,进行增斜、减斜和稳斜钻进,可以控制井斜的方向和强度,精度很高(±0.1°),井深可达13 km,回次长度可以达到1000 m,对于我国深井,特别是地质超深井钻进具有一定参考价值。In deep drilling,with the increasing of borehole depth,drilling conditions become more complicated,drilling rate decreases,borehole quality can not be guaranteed,and controlling the borehole direction is difficult.In Russia,the Rotary Steerable System-RSS is used actively with the deflection function of the downhole bit to achieve build‑up,drop and hold of inclination.The accuracy of the system is very high(±0.1°),the depth of the borehole can reach 13 km with the the drilling length per run up to 1000m.The system can provide reference for deep drilling,particularly for ultra deep geological drilling in China.
