There are the b igger d ifferences betw een slim ho le
dr illing techno logy and routine boreho le dr illing techno logy.
Improv ing o f slim hole drilling speed is of an im po rtan t actua l
significance. This artic le studied the lim itation of the sma llsize
dr iv ing force drilling too ,l and carr ied out se lec tion of
dr illing too l com b ination of slim hole, and considered the
w ork ing character istic o f slim ho le. The optimum drilling
param eters are ascerta ined by theoretica l ca lcu la tion to m ake
the slim ho le bit reach the best w ork ing cond ition in bo ttom
ho le in orde r to ach ieve the optimum ra te of penetration.
