随着海上复杂井和丛式井的广泛应用，对其井身结构的要求越来越高，目前常规动力钻具和导向工具在浅层软地层造斜、浅层防碰和大斜度井电测等方面应用的局限性日益体现，需研制新工具克服其缺点。介绍了一种新型旋转导向工具Power Drive Xceed，是斯伦贝谢公司Power Drive旋转导向系统系列的最新产品，代表了旋转导向最新发展方向。阐述了该工具结构、工作原理、特点及发展现状，并结合在乐东22-1气田成功的现场应用，描述其使用效果，为该工具的推广应用和研究提供了有益参考。

With the development of complex and cluster wells in offshore oil field, well profiles became more and more complicated. The conventional power drilling tool and rotary steering tool generally used now gradually showed their limitation in surface, soft formation angle buildup, surface anti-collision and electric logging in high deviated wells. So, a new drilling tool is needed to overcome these problems. This paper introduced the new-style drilling tool, Power Drive Xceed, which belongs to the latest product of Schlumber rotary steering tool series. Its structure, operating principle, characteristics and development status were summarized here. Combined with its successful application at Ledong 22-1 Gasfield, its effects were described detailed. The drilling practice provides valuable reference to popularizing and applying this tool.
