Title (EN) (METH)ACRYLIC COPOLYMERS AS RHEOLOGICAL ADDITIVES IN DRILLING FLUIDS AND DRILLING FLUIDS COMPRISING SUCH COPOLYMERS
(FR) COPOLYMÈRES (MÉTH)ACRYLIQUES COMME ADDITIFS RHÉOLOGIQUES DANS DES FLUIDES DE FORAGE, ET FLUIDES DE FORAGE COMPRENANT DE TELS COPOLYMÈRES
Abstract:
(EN) The invention relates to a drilling fluid in the form of a water-in-oil (W/O) emulsion comprising at least components (A) to (D), wherein component (D) is at least one (meth)acrylic copolymer, which contains at least one of structural units (D1), (D2) and (D3) to introduce at least one hydroxyl and/or amino functionality into the copolymer and which further contains at least one structural unit (D4), a use of said(meth)acrylic copolymer as rheological agent in drilling fluids, which are water-in-oil (W/O) emulsions, as well as to a method of producing oil and/or natural gas or of preparing the production thereof comprising the step of using the inventive drilling fluid for generating and/or operating a drill hole.
(FR) L'invention concerne un fluide de forage sous forme d'une émulsion de type eau-dans-l'huile (W/O) comprenant au moins les constituants (A) à (D), le constituant (D) étant au moins un copolymère (méth)acrylique qui contient au moins l'un des motifs structuraux (D1), (D2) et (D3) pour introduire au moins une fonctionnalité hydroxyle et/ou amino dans le copolymère, et qui contient en outre au moins un motif structural (D4), une utilisation dudit copolymère (méth)acrylique comme agent rhéologique dans des fluides de forage qui sont des émulsions de type huileux (W/O), ainsi qu'un procédé de production d'huile et/ou de gaz naturel ou de préparation de la production de ces derniers, comprenant les étapes consistant à utiliser le fluide de forage selon l'invention pour produire et/ou exploiter un trou de forage.
