套管钻井介绍 CASING DRILLING INTRODUCTION
套管钻井有两种方式 •驱动套管钻井 •马达带动下部套管钻井 1999年底以前，绝大多数都是采用马达带 动钻井的方法。The majority of Casing Drilling Jobs to end-1999 used the Latched Motor Method 威德福认为，如果可钻钻头研发成功，套 管钻井会大有市场。Weatherford believed that if a ‘Drillable Drill Bit’ could be developed, Drilling by Rotating the Casing might be attractive in many applications.
