Well flushing operation is an indispensable and important step in the production process of water well drilling rig. Well flushing operation is very important for the production process of water well drilling rig. It can not only improve the production efficiency of water well drilling rig, but also improve the drilling quality of water well drilling rig.

The importance of well flushing operation needs to be carefully understood by the construction personnel, but many construction personnel do not know how to clean the well. Well flushing fluid needs to be injected during well flushing, so how does the well flushing fluid enter the drilling underground? The secret lies in the drill string of the water well drill. The drill string is a hollow pipe string. This design method can allow the well flushing fluid to enter the well through the drill string, and then flow into the well through the water hole of the drill bit. Such repeated use can achieve a good well flushing effect. When the well flushing fluid volatilizes into gas, the well flushing operation is probably completed.

In the water well drilling rig, the drilling operation and well flushing operation need to be carried out at the same time. The drill bit constantly breaks the underlying rock, and the well flushing fluid is continuously injected for well flushing operation. Therefore, in order to maintain the uninterrupted flow of the well flushing fluid, the pump needs to be used for continuous irrigation injection, so as to meet the well flushing requirements of the water well drilling rig.
