●优化扩眼翼角设计实现了平稳、安全、有效的井底扩眼， 最大的井径扩大率达到了25%;

●采用IDS设计软件使钻头设计更加合理，优化了领眼和 扩眼的布齿结构，最大限度地减少钻头在井底的偏心运 动，实现平稳切削，提高钻头寿命。

·The optimized wing angle design achieves smooth,safe,and effective bottom-hole enlargement,with a maximum borehole enlargement ratio of 25%.

·The use of IDS design software enables a more rational  drill  bit  design,optimizing  the  tooth structure  of  the  leading  and  expanding  bits, minimizing the eccentric motion of the drill bit at the bottom   hole,achieving   smooth   cutting,and improving the drill bit life.
