Wear resistance of teeth ofconventional steel tooth cone bit is not good, tooth shape structure is lack ofoptimization, which leads to decrease of average ROP. Deris newly designed steel tooth bit with high efficiency can solve these problems, with strong wearresistant teeth and fast ROP, bit can work more stably, which is more suitablefor drilling in soft or middle soft formations with high rotaryspeed.Application of our steel tooth bit with high efficiency is the best way tosolve the problem of increasing drilling speed in higher part ofwell.
