How to ensure the stability of the wellbore during the drilling process?

During the drilling process you can ensure the stability of the well wall ah by the following methods.

Casing can be installed in time to protect the well wall from collapsing.

According to the geological situation, choose the drilling speed and strength reasonably, not too fierce and too fast, otherwise it is easy to cause damage to the well wall.

Use the appropriate mud, mud can play the role of wall protection, so that the well wall is stronger.

In the drilling process, we should always observe the well wall, once found signs of instability, we should take timely measures, such as adjusting the drilling parameters or increasing the means of wall protection.

Also pay attention to maintain the continuity of drilling, do not stop for a long time, or it may also affect the stability of the well wall.
