Title (EN) INTERCHANGEABLE WELLBORE CLEANING MODULES
(FR) MODULES INTERCHANGEABLES DE NETTOYAGE DE PUITS DE FORAGE
Abstract:
(EN) A system for cleaning a wellbore can include a bottom hole assembly that is designed to be run downhole into a wellbore after the wellbore has been drilled and before the wellbore has been cleaned. A control sub-assembly is mounted on and carried by the bottom hole assembly. The control sub-assembly is designed to be positioned within the wellbore. Multiple cleaning sub-assemblies are interchangeably mounted on and carried by the bottom hole assembly. Each cleaning sub-assembly is designed to be positioned within the wellbore. The multiple cleaning sub-assemblies include at least two of the following sub-assemblies: a scraping sub-assembly that scrapes an interior of the wellbore, a brushing sub-assembly that brushes the interior of the wellbore, or a magnetic sub-assembly that magnetically captures debris within the wellbore.
(FR) L'invention concerne un système de nettoyage de puits de forage pouvant comprendre un ensemble fond de trou qui est conçu pour être descendu dans le fond du trou d'un puits de forage après forage du puits de forage et avant nettoyage dudit puits de forage. Un sous-ensemble de commande est monté sur l'ensemble fond de trou et transporté par celui-ci. Le sous-ensemble de commande est conçu pour être positionné à l'intérieur du puits de forage. De multiples sous-ensembles de nettoyage sont montés interchangeables sur l'ensemble de fond de trou et transportés par celui-ci. Chaque sous-ensemble de nettoyage est conçu pour être positionné à l'intérieur du puits de forage. Les multiples sous-ensembles de nettoyage comprennent au moins deux des sous-ensembles suivants : un sous-ensemble de raclage qui racle l'intérieur du puits de forage, un sous-ensemble de brossage qui brosse l'intérieur du puits de forage, ou un sous-ensemble magnétique qui capture magnétiquement des débris à l'intérieur du puits de forage.
