Title (EN) ENHANCED SMEAR EFFECT FRACTURE PLUGGING PROCESS FOR DRILLING SYSTEMS
(FR) PROCESSUS AMÉLIORÉ D'OBTURATION DE FRACTURE À EFFET DE MACULAGE POUR SYSTÈMES DE FORAGE
Abstract: front page image
(EN)This invention relates to drilling a well, particularly an oil or gas well, to permit longer periods of drilling and longer lengths of casing or liner to be installed at one time. The present invention includes a combination of a smear tool and specially sized granular lost circulation material solids in the drilling fluid which work together to close and seal leaking formations and fractures whether pre-existing or induced by drilling.
(FR)L'invention concerne le forage d'un puits, en particulier un puits de pétrole ou de gaz, pour permettre de plus longues périodes de forage et de plus grandes longueurs de tubages ou des chemises à installer en une fois. L'invention concerne notamment une combinaison d'un outil de maculage et des solides de matériau de perte de circulation particulièrement granulaire dans le fluide de forage qui collaborent de façon à fermer et étanchéifier des formations et fractures non étanches, qu'elles soient préexistantes ou induites par forage.
