A process for using high molecular weight, anionic, hydrophilic polymers without formation of deleterious emulsions to facilitate flow in multiphase pipelines containing both oil and water (e.g., oil/water, oil/water/gas, oil/water/solids, and oil/water/gas/solids) such as are used for oil or gas production, gathering, and transmission; hydrotransport of oilsand or heavy oil slurries is described. Specific examples of suitable drag reducing polymers include anionic, hydrophilic polyacrylamides having a molecular weight of greater than 1 megadalton.
La présente invention a trait à un procédé pour l'utilisation de polymères hydrophiles anioniques de poids moléculaire élevé sans formation d'émulsions délétères pour faciliter l'écoulement dans des canalisations multiphasiques contenant à la fois du pétrole et de l'eau (par exemple, pétrole/eau, pétrole/eau/gaz, pétrole/eau/solides, et pétrole/eau/gaz/solides) telles que celles utilisées pour la production, la récupération, et la transmission de pétrole et de gaz, l'hydrotransport de pétroles et de suspensions d'huiles lourdes. Des exemples spécifiques de polymères aptes à la réduction de résistance de frottement comprennent des polyacrylamides hydrophiles anioniques ayant un poids moléculaire supérieur à 1 mégadalton.
