The drill pipe is fixed on the main hoisting reel by a wire rope, and the drill pipe can be raised or lowered correspondingly when the reel is wound or the wire rope is placed. The power of the reel comes from the main hoisting motor that has been decelerated several times. Its stopping is achieved by the brake directly mounted on the reducer.
Since the 1990s, the well-drilling technology has begun to develop rapidly abroad. At present, the number of well-drilling equipment equipped globally has exceeded 15,000, and will exceed 20,000 in 2011, and it is still increasing. In many developed countries, well drilling has become a routine drilling technique. For example, drilling wells in the United States and Canada account for about one-fifth of the total wells in the country.
The drilling machine uses the triangular support to make it firm and reliable. The construction personnel regularly inspect the supporting part and find hidden dangers in time.
Application and development of three drilling technologies In recent years, three drilling technologies have been developed and widely used.

The application of the three technologies has achieved remarkable results. In recent years, the application and development of the three major drilling rigs have driven the rise of a number of industries and promoted the renewal of ideas.
