Abstract
Aiming at the selection of lip shape of diamond bits, and starling with the rock breaking mechanism, the authors discussed the rock crushing process under pressure heads with different lip shapes. Based on the field test and the comparison uf bit lips of flat type, staggered type and concentric teeth type,it was found that the concentric teeth type had the best comprehensive effect. In the actual drilling production, the drilling efficiency could be improved by selecting the relevant bottom lip shape of diamond bit.关键词
