DTH drill pipe currently has a low application range in some excavation and drilling fields, but in terms of performance, its future development trend is very good, and its use-value is very high, especially for some deep wells and rocks with high hardness For complex geological conditions, this drill is undoubtedly excellent. Therefore, the future of DTH drill pipes is very broad. Of course, it still needs certain development in technology before it can become mature.

　　So what is the reason that limits the development of DTH drill pipes? First of all, it is indeed defective in some aspects. For example, the drilling speed is low, and it cannot meet certain requirements, resulting in a very low use value at present. This is the most common phenomenon in current equipment, which is caused by insufficient power in water and insufficient mechanical braking power.

　　Of course, some domestic DTH drill pipe companies have not given up research on their performance. Many drills have been developed and great breakthroughs have been made in technology. After years of development, a variety of serialized and large-size drill bits and machines have been developed, which are fully suitable for large-size drilling and can achieve higher speeds.

　　DTH drill pipe has good advantages and characteristics in many aspects, and has a high development space in mechanical crushing power, which can meet the rock excavation ability of higher hardness; and also has sufficient anti-fatigue and wear resistance. In terms of cutting teeth, the number of cutting teeth is increased, and the size is reduced, which is more conducive to the cutting teeth eating into the formation.

　　DTH drill pipe mainly includes several parts: bypass valve, hydraulic motor, universal shaft, and transmission shaft. The motor mainly provides power, which directly affects its speed and load, which is the main factor restricting the development of domestic DTH drill pipes. However, with the continuous maturity of drill bit technology, its application prospects are becoming more and more extensive.
