An inhibitive water-based polymer mud system and method for using the system in drilling and in stabilizing wellbores is disclosed for use in water sensitive formations as an alternative to oil-based muds. The system comprises a substantially non-ionic low molecular weight polyacrylamide in combination with a substantially non-ionic high molecular weight polyacry-lamide, preferably long chain alcohol or an amine or silicate shale inhibitor, and poly anionic cellulose.
L'invention concerne un système de boue polymère inhibiteur à base d'eau et un procédé d'utilisation du système pour le forage et la stabilisation de puits de forage, ledit système étant destiné à être utilisé dans des formations sensibles à l'eau comme alternative aux boues à base d'huile. Le système comprend un polyacrylamide sensiblement non ionique de faible poids moléculaire associé à un polyacrylamide sensiblement non ionique de poids moléculaire élevé, de préférence un alcool à longue chaîne ou un inhibiteur du gonflement des argiles schisteuses à base d'amine ou de silicate, et de la cellulose polyanionique.
