Title
(EN) WELL CLEANUP TOOL WITH REAL TIME CONDITION FEEDBACK TO THE SURFACE
(FR) OUTIL DE NETTOYAGE DE PUITS À RETOUR D'ÉTAT EN TEMPS RÉEL VERS LA SURFACE
Abstract
(EN)
A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.

Incorporation de capteur de flux dans un panier de repêchage pour la détection d'arrêt de flux dû à un filtre bouché ou à des sorties de rognures bouchées dans un broyeur. Le capteur déclenche un signal vers la surface pour avertir le personnel de la survenue d'un problème avant l'endommagement d'équipement. Ledit signal peut prendre diverses formes, y compris des impulsions d'ébouage, une accumulation de pression détectable à la surface, de l'énergie électromagnétique, un signal électrique par câble ou des signaux radio dans un système Wifi, pour prendre quelques exemples. Le personnel de surface peut interrompre le signal pour prendre des mesures correctives qui consistent généralement en un retrait du trou ou en une circulation inverse pour tenter de nettoyer le filtre ou les sorties de rognures de broyeur. On peut mesurer d'autres variables comme le volume ou le poids ou le taux de variation de l'un ou de l'autre, et un signal peut être envoyé à la surface, correspondant à l'une de ces variables, pour en permettre la détection à la surface presqu'en temps réel.
