Command Well Drilling Equipment With Strong Wall Protection Ability
Efficient And Comprehensive Drilling Technology Alternative Air Dth Hammer
Advantages of mud drilling:
(1) Strong wall protection ability to avoid accidents at the bottom of the hole to the greatest extent
(2) Not affected by depth
(3) Not affected by the formation
4. Air DTH hammer has great limitations, its disadvantages are as follows:
(1) High air compressor price, high fuel consumption, high maintenance cost
(2) Only for hard rock stratum, the harder the stratum is, the higher the efficiency is. However, once encountering soft sand or clay stratum, the hole will collapse or other drilling accidents will occur.
5. In order to combine the advantages of mud drilling and air DTH hammer, we have developed a liquid driven DTH hammer, which has the

Unsuited Stratum :The mud acts as a medium for the impactor, essentially mud drilling. Mud drilling is suitable for a variety of formations. And the wall protection ability is strong, it is not easy to collapse, and the fractured formation can also be processed by filling.
