The invention concerns a method for transporting a viscous product in a pipe (C) by cavity lubrication flow technique, and limiting the restart pressures required for circulating the viscous product. Cavity flow is a technique enabling a very viscous product to be transported in a pipe with reduced pressure drops. However, when there is a difference of density between the fluids, the transverse movements of the viscous product towards the walls cause stratification and the restart pressures are then very high, since the viscous portion must be deformed. In order to limit said pressures, it is proposed that the transverse movements should be limited by injecting into said pipe a threshold fluid enabling resistance to transverse movements to be generated. To obtain such a threshold fluid, additives may be added into the water layer currently used. The invention is useful in particular for transporting viscous hydrocarbons.

Méthode s' appliquant au transport de produit visqueux dans une conduite (C) par écoulement en régime de lubrification pariétale, et permettant de limiter les pressions de redémarrage nécessaire à la mise en circulation du produit visqueux. La lubrification pariétale est une technique permettant le transport en conduite de produit très visqueux avec des pertes de charge réduites. Cependant, en cas de différence de densité entre les fluides, les déplacements transverses du produit visqueux vers la paroi conduisent à une stratification et les pressions de redémarrage sont alors importantes, car il faut déformer la partie visqueuse. Pour limiter ces pressions, il est proposé de limiter les déplacements transverses en injectant dans ladite conduite un fluide a seuil permettant d'engendrer une résistance aux déplacements transverses. Pour obtenir un tel fluide à seuil on peut ajouter des additifs dans la couche d'eau classiquement utilisée. Application notamment au transport des hydrocarbures visqueux.
