油田及天然气钻井中，刮刀钻头已经获得广泛的使用，今后随着地质工作的进展，物理探矿工作的配合，不采取岩心的钻进方法，在地质钻探上亦将逐步得到推广。因此对刮刀钻头的几何形状、翼片形式及补强翼片的工艺进行一些研究讨论是十分必要的。本文重点拟对后者作以下简单介绍，以便野外修配间迅速掌握这一技术。 Drilling bit has been widely used in oilfield and natural gas drilling. With the progress of geological work and physical prospecting work in the future, the core drilling method will not be adopted and geological drilling will be gradually popularized. Therefore, it is necessary to do some research and discussion on the geometry of the drag bit, the form of the flaps and the process of reinforcing the flaps. This article focuses on the latter to make the following brief introduction, in order to quickly grasp the field between the repair shop.
