Detailed Product Description

High Light:

air lift reverse circulation drilling technology

air DTH drilling technology

EFFICIENT AND COMPREHENSIVE DRILLING TECHNOLOGY ALTERNATIVE AIR DTH HAMMER

1. Our products can use various drilling technologies, such as mud drilling, air DTH drilling, air lift reverse circulation drilling, etc

2. Mud drilling is applicable to all kinds of formation conditions and is a universal drilling technology. With the progress of the times, air DTH hammer drilling has gradually emerged

3. 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 following advantages:

(1) Use mud as the medium to drive the impactor to avoid damage to the impactor due to high temperature and have enough lubrication

(2) Because mud is used as medium, it has strong wall protection capacity and provides safety

(3) It has the same impact principle as air DTH hammer, and has excellent crushing capacity for rock

Conclusion: liquid driven DTH hammer is the trend of drilling industry

Comparison of liquid-driven hammer drilling process and air DTH hammer drilling process
DTH-HAMMER				COMMAND liquid-driven hammer
Applicable strata
Complete bedrock formation, or hard rock				Like the DTH-hammer, the crushing efficiency is extremely high for hard formations. 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.
Unsuited Stratum
Sandy soil layers, fractured strata and other loose formations, when loose formations will blow up the walls of the holes, or blow into small "big bells", if the air compressor model is not well matched, it will cause drill cuttings at the bottom of the hole. Suspended in the wellhead, can not blow out, resulting in buried bottom and other hole bottom accidents.
Matching equipment
Drilling rig				Drilling rig
Generally hydraulic power head drill The rig is a combined I-beam or channel steel structure that is lightweight but does not have torsion resistance. Therefore, it is only applicable to the air DTH hammer drilling process which does not require a large torque, and the general aperture can only reach within 200MM.				The rig can be in various forms, and the COMMAND uses a truss structure, which is a high-strength square tube welding, has a high load and good torsion resistance, and is suitable for various aperture construction. The drilling diameter is 505MM.
Air compressor				Mud pump
Selection basis: Air flow: annular gap between drill pipe and hole wall (aperture) Wind pressure: depth Commonly used air compressors can only reach a depth of about 280 meters, the deeper the cost is, the higher the cost is.				Selection basis: Flow: Ring gap between drill pipe and hole wall (aperture) Pressure: Depth Mud pump is the basic component of drilling rig. Because of the ever-changing strata, mud drilling must be used to solve complex strata. The selection of mud pump only needs to be based on the depth and aperture of normal mud drilling.

Other
Daily use cost: Fuel consumption: Because of its working principle, screw air compressor is basically driven by diesel engine, and must be a high-powered diesel engine, which consumes a lot of fuel in daily use. Maintenance: Because of the high precision of screw air compressor, air filter and screw oil must be selected with better specifications, and must be replaced regularly, with higher cost. Accessories: Accessories are expensive. Operation: There are many electronic components, such as electronic control, and many fault points..				Daily use cost: Fuel consumption: no different from normal drilling Maintenance: Normally replace the fragile parts of the mud pump. Accessories: Low Price of Parts and Components Operation: Simple mechanical operation, low failure rate
