Well cleaning operation steps explained by DTH drilling rig manufacturer
The well cleaning operation is an indispensable and important step in the working process of the water well drilling rig. The well cleaning operation is very important to the production process of the water well drilling rig. It can not only improve the production efficiency of the water well drilling rig, but also improve the drilling quality of the water well drilling rig.

The well cleaning operation of DTH drilling rig requires the constructor to carefully understand, but many construction workers do not know how to clean the well. Well cleaning fluid needs to be injected during well cleaning operations, so how does the well cleaning fluid enter the drilling underground? The secret lies in the drill string of the water well drilling rig. The drill string is a hollow pipe string. This design method can allow the well cleaning fluid to enter the well through the inside of the drill string and flow into the well through the water hole of the drill bit. Repeatedly A good well cleaning effect can be achieved by using it. When the well cleaning fluid volatilizes into gas, the well cleaning operation is almost completed.
During the working process of the DTH drilling rig, the drilling operation and the well cleaning operation need to be carried out at the same time. The drill bit continuously breaks the underlying rock, and the well cleaning fluid is continuously injected to perform the well cleaning operation. Therefore, in order to maintain the uninterrupted flow of the well cleaning fluid Flow requires the use of a pump for continuous irrigation injection, so as to meet the well cleaning needs of the water well drilling rig.
