Modelling of an effluence of drilling fluid from hydraulic holes of PDC bits

Abstract

In this article some results of mathematic modelling of an effluence of drilling fluid from hydraulic holes of PDC bit are presented. Distribution of velocity and pressure in borehole bottom are received, and erosion of interior surface of hydraulic channel of PDC bit is researched.
