The rate of penetration of PDC bits relates closely to its self-sharpening property.

复合片钻头的钻速与其切削齿的自锐性密切相关,钻头台架试验反映了这种内在联系,并用平均钻速((?))和平均钻速变化率((?))等指标对复合片自锐性能进行描述与评价。

The analyses of the relationship between drilling parameter and rate of penetration was done,and the principle of coupled driven drilling by improving rotary speed of bit was revealed to increase bit rock-breaking energy to improve penetration rate.

分析了钻井参数与钻速的关系,揭示了复合钻井通过提高钻头转速,从而增加钻头破岩能量来提高机械钻速的机理;在分析井斜原因和钟摆钻具防斜打直原理的基础上,分析了直螺杆钻具和弯外壳螺杆钻具组合的防斜机理以及两者的联系与区别,指出在地层倾角较小时采用直螺杆钻具组合,地层倾角较大时采用弯外壳螺杆钻具组合,以达到防斜打快的目的。
