Numerical modeling on drilling fluid and cutter design effect on drilling bit cutter thermal wear and breakdown

Türkiye 15.Madencilik Kongresi/15* Mining Congress of Turkey, GäyagüIcr,Ersayin,BiIgen(cds)© 1997, ISBN 975-395-216-3 A CRITICAL REVIEW OF FACTORS INFLUENCING THE WEAR OF THERMALLY STABLE DIAMOND (TSD) ROCK DRILLING BITS

In rock drilling, bit wear is a major factor in determining bit life, the cost of drilling and may significantly influence the drilling method selected for given rock type. Effective control of bit wear can yield significant cost savings. Prediction of cuttability or drillability requires an understanding of the cutting action and the mode of wear and their interaction with the rock propertiesW...

An Experimental Study of the Effect of Amines on Polymer Efficiency and Thermal Stability of Water-based Drilling Fluid

Amine compounds are believed to have acceptable results regarding their use as clay swelling inhibitor and corrosion inhibitor additives in drilling fluids. It is crucial to know the capability of amine compounds to enhance the thermal stability of drilling fluid; herein, a water-based fluid composed of biopolymer and other additives as the proper representatives of muds used in the pay zone se...
