摘　　要：大位移钻井尤其是高水垂大位移钻井项目施工,始终是我国钻井领域中不断探索的技术内容之一。科学合理地应用大位移钻井技术,能显著提升水域内油气资源的开发率。文章结合LS01-UG井工程,较为详细地探究了大位移钻井的几项关键技术,分别是钻井裸眼延伸极限预测与控制、降阻与降扭矩、计算机为导向实现实时钻进监测及LS01-UG井的钻进措施等,希望能和同行分享经验与方法,进而为大位移井稳定开采提供更可靠的理论依据。Large displacement drilling,especially the construction of high water vertical large displacement drilling project,has always been one of the technical contents of continuous exploration in the field of drilling in China.Scientific and reasonable application of large displacement drilling technology can significantly improve the development rate of oil and gas resources in water areas.With the LS01-UG well engineering,this paper explores several key techniques of large displacement drilling in detail,namely,prediction and control of the extension limit of drilling bare hole,resistance and torque reduction,computer-oriented real-time drilling monitoring and drilling measures for LS01-UG,etc.,hoping to share experiences and methods with peers,and then provide more reliable theoretical basis for stable mining of large displacement wells.
