1)For single cone bits with different offset distances, the transmission ratio changed slightly with rotary speed of bit and weight on bit,. The designers need not to consider the influence of offset distance when designing the cutting structure of single-cone bit.

2) The rate of penetration of the offset single-cone bit increased with increase of WOB and offset distance, Designers could increase offset distance properly in order to increase ROP when designing the bit.

3) The torque on bit increased with increase of offset distance under the same expermental conditions, so the influence of torque on bit on the strength of drilling pipe should be considered.

4) The bottom holes drilled with single-cone bits with different offset distances had different track patterns. The probability that broken rock was crushed again by teeth decreased with increase of offset distance, thus increasing rate of penetration and drilling efficiency.
