THE REASEARCH AND APPLICATION OF ANTI-WHIRL PDC BIT IN ABROAD
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.
