People who are often engaged in geological exploration of solid minerals should have a good understanding of core drilling. As a special method of geological core drilling, follow-up drilling should not be unfamiliar to related workers.

What is follow-up? The follower pipe is a kind of metal pipe made by Guojin Metal, which is used for the follower drilling construction. Although the tube-following drilling technology can easily solve the problems encountered during survey or construction, it has very high requirements for tube-following, and the equipment used needs to be equipped with a variety of drilling tools. And the configuration of the drilling tool should be as good as possible, because the drilling efficiency is largely affected by it.

When performing follow-up drilling, press in the casing while drilling, or press in the casing in advance, and then follow the drilling tool. This drilling method can avoid hole wall collapse and quicksand stuffing in the drilling process, so this method is suitable for drilling in loose formations and quicksand layers. In large-diameter engineering drilling, because casing running requires large torque and power, a machine called a tube rubbing machine is often equipped to perform casing running while drilling. In addition, it is also one of the effective methods to deal with overburden drilling.

Follow-pipe drilling is divided into eccentric follow-pipe drilling and concentric follow-pipe drilling. Eccentric follow-pipe drilling is suitable for stratums where the hole depth is less than 40 meters and there are no large stones. Concentric drilling is the opposite. In formations with a depth of more than 40 meters, there are more larger stones used.

When construction encounters soft geology with broken layers, or formations that are difficult to make holes, in this case, ordinary drilling methods are difficult to carry out construction. At this time, follow-pipe drilling can be used, which not only solves the problem , Also greatly improved work efficiency.

So what is follow-up management? The follower pipe is a kind of metal pipe made by Guojin Metal, which is used for the follower drilling construction. Although the tube-following drilling technology can easily solve the problems encountered during survey or construction, it has very high requirements for tube-following, and the equipment used needs to be equipped with a variety of drilling tools. And the configuration of the drilling tool should be as good as possible, because the drilling efficiency is largely affected by it.

People who are often engaged in geological exploration of solid minerals should have a good understanding of core drilling. As a special method of geological core drilling, follow-up drilling should not be unfamiliar to related workers.
