摘要
In this paper, a large diameter reinforced diamond bit was developed, which has advantages over traditional diamond bit in wearing-resistance, anti-impact toughness and bit diameter retention. The bit service life in gravel and broken formations and drilling rate were improved with no changes of traditional drilling parameters.
