摘 要:将仿生非光滑理论应用于螺旋钻头设计上,以解决粘性土钻进中螺旋钻头阻力大、粘附严重的难题。加工的仿生非光滑螺旋钻头,经实钻试验表明,与常规螺旋钻头相比,前者脱土率提高了70%,钻机耗油量降低了53.3%,钻进效率提高70%,具有明显的脱附和减阻效果。从而,为大口径螺旋钻施工提供了一种新型钻具。The bionics theory was applied on the spiral bits, and then a non-smooth spiral bit was designed and processed for carried out the problem of serious sticking. Experiments finally proved that the bionic non-smooth spiral bit has a significant effect in the area of desorption and reducing resistance, compared with the conventional spiral bit, the desorption rate and drilling efficiency have been enhanced 70% and the fuel consumption has been decreased 53.3%. So it is novel tool for drilling of large diameter spiral.
