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。
关键词: 螺旋钻头, 仿生非光滑, 减粘, 降阻, 凸包
Abstract: 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.
Key words: spiral bit, bionic non-smooth, reduce the adhesion, reduce resistance, convex hull
