为适应钻探各种不同物理机械性质(抗压强度、岩石可钻性、研磨性、颗粒度、矿物成分、硬度等等)岩矿层的需要,金刚石钻头品种必须在以下四个方面得到应有的重视和发展:①唇部造型;②胎体具有不同硬度,尤其以孕镶钻头的胎体硬度最为重要;③镶嵌不同粒度、不同浓度、不同嵌入量的金刚石;④配有不同式样和数量的水路(水口、水槽).本文着重探讨金刚石钻头的唇部造型设计问题.金刚石钻头唇部(包括
To meet the needs of rock and mineral formations for drilling various physical and mechanical properties (compressive strength, rock drillability, grindability, particle size, mineral composition, hardness, etc.), diamond bit varieties must be found in the following four areas Emphasis and development: ① lip modeling; ② carcass with different hardness, especially pregnant impregnated bit matrix hardness is the most important; ③ inlaid with different particle size, different concentrations, different amounts of embedded diamond; ④ with different styles and quantities Of the waterway (nozzle, sink) .This article focuses on the design of the diamond bit lip modeling.Drill bit lip (including
