The first one is passive adsorption of drilling tools.
The second one, the front end of the drilling tool is wrapped by a large amount of mud.
The third type, collapse stuck drilling.
The main reason for the appearance of the above three situations, the construction personnel in the process of daily drilling operations in the operation of the equipment is unreasonable, so the relevant personnel need to start from the actual situation to carry out a more in-depth discussion on it in order to find the specific reasons that lead to the occurrence of jammed drilling situation, and then apply the appropriate methods to deal with it, in order to reduce the frequency of jammed drilling accidents.
