SYSTEM FOR DISCLOSING ASPECTS OF ASPECT BATTERY OF A PERFORMANCE EQUIPMENT.

摘要

Unstuck system (10) of stuck drill pipes (25) of a drill string (20) of a drilling apparatus (100) adapted to drilled wells to extract fluids or mud, a torsion coupling system (40) adapted to disconnecting an upper portion (21) from a bottom portion (23) comprising the stuck drill pipes (25) of the drill string (20) and to transfer a rotation to the unstuck system (10) which comprises at least an axial forced vibration generator (11, 12, 13) comprising at least one axially movable element (50, 51, 94, 95, 96) adapted to generate at least a vibration which is propagated to pipes (20) of a portion free from stuck (24), where the induced vibrations fall within a band of induced frequencies (ϑF) near or corresponding to a resonance frequency (ϑ0) of the portion free from stuck (24).
