摘要: Expandable reamer assemblies include an expandable module and activation module. An outer tubular body of the is rigidly coupled to a module, member sleeve at least one blade configured move into extended position. The moves axially responsive axial movement member. Bottom-hole provide motive force opposite direction flow drilling fluid. Methods using modules pairing two substantially identical respective different modules.
