Abstract

processo de injeção com água para recuperação secundária de hidrocarbonetos. a presente invenção refere-se a uma composição de injeção de água em um proceso de recuperação secundária de hidrocarbonetos. a composição de injeção de água e um polímero espessante. o polímero espessante inclui um esqueleto polimérico de hidroxietilcelulose, tendo um peso molecular entre cerca de 1.000.000 e cerca de 2.000.000, e um modificador hidrofóbico. o modificador hidrofóbico tem um nível de substituição no polímero espessante entre cerca de 0,1 porcento e cerca de 2 porcento em peso do polímero espessante. o modificador hidrofóbico é um material à base de hidrocarboneto de aquila, contendo entre cerca de 10 e cerca de 24 átomos de carbono não substituídos por grupo. o polímero espessante tem uma concentração na composição de injeção de água entre cerca de 0,01 porcento e cerca de 1 porcento em peso da composição de injeção de água. a composição de injeção de água é formulada dentro dessas faixas de modo que a composição de injeção de água tenha viscosidade / mobilidade adequadas, e de modo que a composição de injeção de água seja injetável.water injection process for secondary hydrocarbon recovery. The present invention relates to a water injection composition in a secondary hydrocarbon recovery process. the water injection composition and a thickening polymer. the thickening polymer includes a hydroxyethylcellulose polymer backbone having a molecular weight of from about 1,000,000 to about 2,000,000, and a hydrophobic modifier. The hydrophobic modifier has a thickening polymer substitution level between about 0.1 percent and about 2 percent by weight of the thickening polymer. The hydrophobic modifier is an aquyl hydrocarbon-based material, containing from about 10 to about 24 unsubstituted carbon atoms per group. the thickener polymer has a concentration in the water injection composition between about 0.01 percent and about 1 percent by weight of the water injection composition. The water injection composition is formulated within these ranges so that the water injection composition has adequate viscosity / mobility, and so that the water injection composition is injectable.
