【摘要】 仿生学是一门可与很多学科交叉的边缘性学科,其与钻头设计制备技术的融合将产生创新性成果。为提高孕镶金刚石钻头钻进速度和工作寿命,基于仿生耦合理论,遵循仿生学相似原理,以土壤动物的爪趾为仿生原型,结合孕镶金刚石钻头的总体结构,采用无压浸渍烧结法,设计制备了爪趾型仿生金刚石钻头。通过现场钻井试验,试验数据表明:相比于普通金刚石钻头,爪趾型仿生金刚石钻头平均钻进速度提高了20%~37.9%,平均工作寿命提高了1.23~2.83倍,综合效果显著提高,可为缩短钻孔周期、节约钻孔成本做出较大的贡献,具有深远的经济效益。更多还原

【Abstract】 Bionics is a borderline subject,also can be integrated with the bit design preparation technology will produce innovative results.To improve the impregnated diamond bit drilling speed and the working life,based on the bionic coupling theory,follow the principle of bionics is similar,with soil animal claw toe for bionic prototype,combining with the general structure of the impregnated diamond bit,sintering process of non-pressure immersion type design preparation of the claw toe bionic diamond bit.Through the drilling test,a data indicate that compared with the common diamond bit,claw toe shape bionic diamond bit drilling speed is increased by 20%-37.9%on average,1.23 to 2.83- fold increased average working life,the comprehensive effect is significantly increased,to shorten drilling cycle,saving the cost of drilling to make greater contribution,has profound economic efficiency.更多还原
