Abstract:

The flexible drill string is one of the key tools to materialize the high accuracy directional drilling technique. The brief description is made of the foreign and national technical advances, main technical key points, main technical specifications, structure and composition. Its performance has been tested to the extent that the flexible sub can provide enough resistance to tension, compression and torsion.
