To control deviation, the actual WOB is usually adopted in the lower range, which results in ROP increasing is unconspicuous and predominance of gas drilling can't be showed.
在实际气体钻井过程中，为了控制井斜，通常都将钻压控制在较低的范围内，这就导致气体钻井提高机械钻速不明显，不能充分发挥气体钻井的优势。
-
The new bit ′ s cone and bearing are much larger than those of the three cone bit with the same size,therefore the new bit can bear a greater WOB,thus,the life of the bearing and cone can be prolonged and then the penetration rate can be raised and the length of bit run prolonged.
与相同钻头尺寸的三牙轮钻头相比，该新型钻头的牙轮尺寸和轴承尺寸要大得多，因此，它可以承受较大的钻压，从而可以提高轴承和牙轮的使用寿命，进而提高机械钻速和钻头的使用寿命。
-
Pneumatic hammer drilling technology with low wob,low rate of revolution and high capacity to break rock is one of the best effective methods to solve the problems of hard rock drilling.It includes air drilling and rotary drilling technology,so its penetration rate is usually two or three times higher than rotary drilling.
空气锤钻井是一种低钻压、低转速、高冲击破岩回转钻进技术，它兼容了气体钻井和冲击回转钻井的优势，其机械钻速一般比回转钻井高，是当今解决硬岩钻井难题的一种有效方法。
-
As for the air percussive rotary drilling, because of its advantages of high ROP, long bit life, light WOB, reduced wear of drill collar, large cuttings, low drilling cost, low formation damage and no lost circulation, it has gained acceptance.
空气冲击回转钻井在一些特定的地层和井眼条件下具有高机械钻速、长钻头寿命、小钻压、较轻钻具磨损、大岩屑、低钻井成本、较轻油层污染和避免井漏等优点，因此很早就被钻井界接受。
