Methods of protecting drilling pipes: There are three main methods of protecting drilling pipes: preventing drilling pipes from colliding, preventing drilling pipes from overturning and preventing drilling pipes from being stressed. 

The first method is to use oil casing to prevent drilling pipe collision. Oil casing can well protect drilling pipes from collisions.

The second method is to use oil casing to prevent the drilling pipe from capsizing. Oil casing can well protect drilling pipes from overturning. The third method is to use oil casing to prevent the drilling pipe from being stressed. Oil casing can well protect drilling pipes from stress.

Other Protection Methods: Besides using oil casing, there are other methods that can help protect drilling tubing. These methods include the use of shields and/or jackets to cover the drill pipe, and the installation of barrier ribs to prevent groundwater from flowing into the borehole. Using these extra protections can help ensure the integrity of the drill pipe, making drilling safer.

Oil casing can effectively protect the drilling pipe from damage, so that it can work normally. In addition to using oil casing, other methods can be used to protect drilling pipes, such as the use of preservatives or overlays. The covering layer can effectively prevent the drilling pipe from being damaged, and at the same time reduce the loss of the drilling pipe. Oil casing is one of the effective methods to protect the drilling pipe, it can effectively prevent the drilling pipe from being damaged. Therefore, when conducting drilling activities, oil casing should be used.
