A variable gauge drill tool stabilizer and method of use

Abstract

The present application relates to drilling equipment technical field, especially to a variable diameter drilling stabilizer and its use method, its technical scheme includes: a variable diameter drilling stabilizer and its use method, including external protection assembly, setting in the flow guide assembly of external protection assembly inside and the built-in component installed in external protection assembly inside, also includes the positioning assembly for positioning flow guide assembly inside external protection assembly sliding distance, the present application relies on the two-way anti-locking mechanism formed by the upper flow guide block and the lower flow guide block can be separated and adapt positioning, avoid giving the same pressure to the inner wall due to the different diameters of the inner wall in the scene, cause the scene inner wall area damage occurs, reduce the operation error of the staff in the case of less understanding of the scene implementation, thereby improve the practicability of the equipment and the safety of the scene.
