1·The location of well and sidetracking engineering design is the key to ensure good effect.
要保证好的效果，井位的选择、侧钻工程设计是关键；
2·This paper mainly discussed the designation and operation of directional sidetracking and well track control.
重点介绍了该井定向侧钻及井眼轨迹控制的设计与施工情况。
3·Small size bent housing screw drill with high build rate must be developed to meet the requirements of sidetracking the short to medium radius horizontal well.
螺杆钻具是其中的一项关键技术，其主要目的是研制满足侧钻中短半径水平井需要的小尺寸高造斜率的弯外壳螺杆钻具。
4·Since 1995, sidetracking operations have been conducted in Zhongyuan Oilfield, and a set of perfect slim hole sidetracking technology has been formed.
中原油田自1995年以来开始进行了老井开窗侧钻小眼井技术，数年的努力形成了一套完善工艺。
5·The plugging removal rate of this system has been remarkably improved compared with the acid fluid system, and its field use in 2 sidetracking horizontal Wells are successful.
复合解堵体系的解堵率比酸液的解堵率有较大幅度地提高。经2口侧钻水平井应用表明，该体系解堵效果明显。
