【 摘 要 】

The article describes innovative approach to designing new generation drilling bits with diamond hard-metal-alloy plates coring in accordance with established regularities. Based on the results of theoretical and experimental investigations the authors have stated the offers on the important aspects of drilling bits with diamond hard-metal-alloy plates coring design optimization. The authors have determined the features of influence of geometry, arrangement and dynamic of diamond hard-metal-alloy plates cutters on rock failure when drilling wells. The description of the stabilizing drilling bit is presented along with reasons for optimum angles of the diamond hard-metal-alloy plates mounting onto the casing.
