When the drill string reaches the critical speed, the drill pipe will vibrate. This vibration often causes the bending, excessive wear, rapid damage and fatigue damage of drill pipe. In particular, the two types of vibration of the drill pipe (wave joint vibration and spring pendulum type vibration) are most unfavorable. The critical speed varies with the length of the drilling tool, the size of the drill tool, the size of the drill collar and the size of the hole.

As a business on the road of development is not only to get down and need a perfect development plan, the most important is how to perfect is the implementation of the development plan, the geological drill pipe as an important part of development of geological exploration industry, the consumers of geological drill rod continuously put forward new demand affects the development direction of the address of the drill pipe. The first step then the implementation of innovation plan is to should take the geological drill rod.

In the increasingly fierce competition in the market is changing, so the products people have more ideas and requirements, so the achievements of the development of geological drill rod to seize the market opportunities of the manufacturers, so I should double the geological drill pipe manufacturers to produce more products with consumers.

If the products produced by enterprises are relatively single, they are not recognized by consumers in the market. Therefore, in the future development, geological drill pipes should continue to shoulder the responsibility of diversified products development.

Perfect the implementation of geological drill rod development plan is one of the important tasks, so the development of geological drill rod to improve people innovative ideas into a new realm, is our life to a more affluent level, therefore the perfect development of geological drill pipe is very important, the perfect development plan is the most the heavy.
