Study on a New Type Self-sharpening Diamond Bit for Drilling in Hard-compact-slipping Formation
摘要
Abstract
According to the difficulties in hard-compact-slipping formation drilling, a new type self-sharpening diamond bit is introduced about its design and the effects of indoor and outdoor tests.The indoor micro-drilling experiments and the field drilling tests show that comparing with ordinary diamond bit, this new self-sharpening one can improve ROP 1-3 times with relatively high bit service life and it is an effective rock breaking tool for hard-compact-slipping formation drilling.关键词
