摘要: This invention relates to an elongated wireline entry device (10) which allows a wirelein tool or coiled tubing with attached be inserted in well bore without disconneciton form the drill string appended thereto introducing bending moments into threaded connectiosn (101, 106, 202) because pin and box of are axial, longitudinal alignment. absence these is required suspend long pendular, therefore heavy, strings forr htthis failure. The angle between ayes passage at most 4.0°.
