摘　　要：大位移井和复杂井眼轨迹的控制须实现连续旋转井下闭环导向钻井 ,这一需求推动了井眼轨迹控制手段的提高 ,为此 ,探讨了适用于旋转导向闭环钻井的井下工具的发展概况 ,提出了比较可行的井下钻井工具发展和研究方向。研究结果表明 ,应重视旋转导向闭环钻井技术的发展 ,静态式可调偏量机构是井下闭环控制的主要方式 ,应采用直接侧向力法控制钻头轨迹。The drilling theory and the requirements of practice give an impulse to improve the well trajectory control technology. It is important to realize the rotary steering closed loop drilling in bottom hole since R.L.Monti has put forth this theory again. In recent years, extended reach well and complex designed well have appeared more and more, which stimulates the research in this field. This paper retrospects the development of bottom hole drilling tools and contrasts several kinds of steering tools available to realize the downhole closed loop drilling technology. The analysis results give the following conclusions: ① The downhole closed\|loop drilling technology is available for well trajectory prediction and control; ② Static adjusting biasing organization is the main type of rotary steering close\|loop tools; ③ The direct lateral force method can be used in drilling control.
