Title (EN) RESUMING INTERRUPTED COMMUNICATION THROUGH A WELLBORE
(FR) REPRISE D'UNE COMMUNICATION INTERROMPUE À TRAVERS UN PUITS DE FORAGE
Abstract: front page image
(EN)Resuming communication along a wellbore after a drilling stand or other occurrence that reduces the flow rate of the drilling fluid into a borehole being drilled in a drilling procedure or causes perturbations in the pressure of the drilling fluid in the borehole by measuring a first flow rate of drilling fluid being pumped into the drillstring during the drilling procedure before adding a section of drill pipe to the drillstring or before the pressure perturbation and increasing the flow rate of the drilling fluid being pumped into the drillstring above the first flow rate after the section of drill pipe has been added to the drillstring or the pressure perturbation has occurred.
(FR)L'invention porte sur la reprise d'une communication le long d'un puits de forage après un arrêt de forage ou un autre événement qui réduit le débit du fluide de forage entrant dans un trou de forage en cours de forage pendant une opération de forage, ou qui entraîne des perturbations de la pression du fluide de forage dans le trou de forage. Ce processus consiste à mesurer un premier débit de fluide de forage refoulé dans le train de tiges pendant l'opération de forage, avant d'ajouter un tronçon de tube de forage au train de tiges ou avant la perturbation de pression, et à augmenter le débit du fluide de forage refoulé dans le train de tiges au-delà du premier débit, une fois que le tronçon de tube de forage a été ajouté au train de tiges ou que la perturbation de pression s'est produite.
