Title
THE REASEARCH AND APPLICATION OF ANTI-WHIRL PDC BIT IN ABROAD
摘要
本文指出了回旋运动对PDC钻头的危害,简要介绍了低摩阻保径和圆环轨道布齿钻头设计,通过大量的现场应用实例详述了这两种PDC钻头的抗回旋效果。
Abstract
This article presented the whirling movement is a main cause of destruction of cutters of PDC bit and introduce the PDC bit’s design with low friction gauge and the ring arrangement of cutters.Through a lot of case of history in applications,the effect of anti-whirling about two type PDC bits mentioned above are described in detail.
