Title (EN) A METHOD FOR DRILLING AND CEMENTING A WELL
(FR) PROCEDE DE FORAGE ET DE CIMENTATION D'UN PUITS
Abstract:
(EN) A method for drilling and cementing a borehole to access at least a portion of a formation of interest, comprising: drilling a borehole using a drill string including an external packer and a drilling assembly to access at least a portion of a formation of interest; using a drilling fluid selected to minimize adverse effects on the at least a portion of the formation of interest when drilling into the at least a portion of the formation of interest; setting the packer to create a seal in the borehole so that (i) an upper drill string/borehole annulus above the packer is isolated from (ii) a lower drill string/borehole annulus below the packer, with the at least a portion of the formation of interest being open to the lower drill string/borehole annulus; and introducing cement above the external packer into the upper drill string/borehole annulus.
(FR) L'invention concerne un procédé de forage et de cimentation d'un trou de forage permettant d'accéder à au moins une partie d'une formation d'intérêt. Ce procédé consiste : à forer un trou de forage au moyen d'un train de tiges de forage qui comprend une garniture extérieure et d'un ensemble de forage afin d'accéder à au moins une partie d'une formation d'intérêt ; à utiliser un fluide de forage sélectionné pour réduire au minimum les effets indésirables sur la ou les parties de formation d'intérêt pendant le forage exercé sur celle(s)-ci ; à installer la garniture afin que soit créé un joint dans le trou de forage de façon (i) qu'un espace annulaire de forage/de train de tiges supérieur situé au-dessus de la garniture soit isolé (ii) d'un espace annulaire de forage/de train de tiges inférieur situé au-dessous de la garniture, la ou les parties de la formation d'intérêt étant ouvertes sur l'espace annulaire de forage/de train de tiges inférieur ; et à introduire du ciment au-dessus de la garniture extérieure dans l'espace annulaire de forage/de train de tiges supérieur.
