仿生孕镶金刚石钻头非光滑度优化设计及试验

Optimization design and test of nonsmooth ratio of bionics impregnated diamond bit

将仿生非光滑高效、耐磨理论应用到地质勘探钻头设计上,针对钻遇地层特性,通过试验优化了仿生孕镶金刚石钻头底唇面的宏观非光滑度。在吉林省桦甸市进行的野外生产试验证明,按被钻岩层特性优化了非光滑度的仿生孕镶金刚石钻头有更高的穿透率和使用寿命。

Efficient and abrasion-resistant bionics nonsmooth was introduced into the design of the geologic survey bit.The macro nonsmooth ratio of the bionics impregnated diamond bit was optimized by test in accordance with different formation characteristics.The field production tests of the optimized bionics bit were performed in Huadian,Jilin province and their results showed that the bionics bit optimized in accordance with the formation to drill demonstrated higher penetration ability and longer service life th...
