顶部驱动钻井系统及其新发展

进入９０年代，顶部驱动钻井在大多数海洋钻井和水平钻井作业中已成为主要的钻并方法。木文在概述顶部驱动装置发展史的基础上，着重介绍了顶部驱动钻井系统安装于现有常规钻机上所必须进行的改造及顶部驱动系统的新发展—侧部驱动系统。此外，文章对顶部驱动与转盘驱动系统及侧部驱动与常规顶部驱动系统进行了对比，指出了各系统的相对优缺点。最后提出了几点建议。

Top-Drive Drilling System and Its Recent Developments

Top-drive drilling system have become the predominant method for drilling most offshore wells and horizen tal wells in the 1990's. Based on the developmental history of top-drive system, the paper mainly discusses the rig modifi cation requirement for a top drive to be installed on the existing rigs and introduces the recent development of the top drive -side drive system. In addition,the paper will provide a detailed comparison of the rotary table system with the top-drive and the conventional top drive with the side drive system, and analyse the relative advantages and disadvantages of each system I the several proposals are made by the authors. The results presented will give the potential users with the necessary information to evaluate their applications and select their systems.
