Abstract:

Stabilizer is an important component in BHA of hole deviation control. Up to now, the conventional and nonadjustable stabilizers have been still used widely in the many drilling operations .The information of this type stabilizer is too little to reflex design of all the stabilizers. However, the American stabilizer has the varied style and the plentiful information, especially, there is much reference worth in their integration construction and thee style of stabilized section .Through the information of drilling string stabilizer from USA has been sorted and synthesized, their design types and configurations of stabilized section were described in the paper in details. It provided references for the stabilizer design, manufacturing and application.

Key words: stabilizer, design types, stabilized section, configuration.
