冲击钻井
,no edit summary
- Can drill hundreds of feet (one well hand-drilled in China in 1923 was over 4000 feet deep).能够钻井几百英尺（中国一座1923年手工挖掘的井深达4000余英尺）。 <br>
- Can drill further into the water table than dug wells, even drilling past one water table to reach another.与挖井相比，冲击钻井能深入地下水位更深，甚至可以超过一个地下水位而达到另一个。 <br>
| valign="top" | - The equipment can be very heavy and relatively expensive. 钻井设备可能很重， 相对而言也较昂贵。<br>- Especially in harder rock the method is slow (weeks, rather than days). 尤其当岩石更为坚硬时，这一钻井方法较慢（需要几周，而不仅是几天） <br>
- When temporary casing has to be used, the time taken driving and removing it can significantly increase drilling time.<br>
- Equipment costs are high and the method is slow (resulting in high cost / drilled meter). <br>
