Title (EN) METHOD AND SYSTEM FOR PIPE CONVEYED LOGGING
(FR) PROCÉDÉ ET SYSTÈME DE DIAGRAPHIE TRANSPORTÉE PAR TUBE
Abstract:
(EN) Method and system for pipe conveyed logging (PCL) operations in which the drillpipe conveys a logging tool. The method and system coordinate operation of a wireline winch and drilling rig control systems to synchronize their operation, and/or the method and system attenuate the pull force applied to an upper end of the cable and transmit the attenuated force toward a lower end of the cable to reduce the risks of premature cable release and cable damage.
(FR) L'invention concerne un procédé et un système pour des opérations de diagraphie transportée par tube (PCL) dans lesquelles le tube de forage transporte un outil de diagraphie. Le procédé et le système coordonnent le fonctionnement d'un treuil à câble et de systèmes de commande d'appareil de forage pour synchroniser leur fonctionnement, et/ou le procédé et le système atténuent la force de traction appliquée à une extrémité supérieure du câble et transmettent la force atténuée vers une extrémité inférieure du câble pour réduire les risques de relâchement prématuré du câble et d'endommagement du câble.
