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。

You have woods 1, 3, 5, irons from 3 to 9, pitch wedge, sand wedge and putter, totally 13 clubs.

您有1，3，5号木杆，铁杆3到9号，劈起杆，沙坑杆和推杆，总共13根。

This shaft not only with the original carbon fiber shaft flexibility and have a very strong anti-torque performance, in the swing of energy transfer than ordinary carbon rod to improve a lot, so with this body not only of the DRIVER Ultra distance and stability is far superior.

这种杆身不但具有了原有碳纤维杆身的弹性而且拥有了很强的抗扭力性能、在传递挥杆的能量时也比普通的碳杆提高了很多，所以配备这种杆身的DRIVER不但距离超远而且稳定性也超强。

The results showed that the performance of the drill pipe joints was in line with standard and the main reason was that the making up torque was inadequate.Drill pipe joints in underground unrestrained tightening-up caused the drill pipe joints to bear the excessive load more than their anti-torque yield strength.

结果表明：钻杆接头的各项性能指标均符合标准规定，失效的主要原因是上扣扭矩不足，钻杆接头在井下无节制旋紧，致使钻杆在井下的自上扣扭矩超过了钻杆接头的实际抗扭屈服强度。

On the basis of designing and constructing the anchor man pole- anchor man unites supporting, observing the transmutation of tunnel via installing the monitor and analyzing the dates, educe the conclusion that bolting support in depth high stress is a valid method, give the accordingly economic and reasonable support parameter and put forward the support countermeasure for mining tunnel with high stress at depth.
