Abstract

Foreliggende oppfinnelse vedrører anvendelsen av polymerer, som består av en eller forskjellige anioniske monomerer og av en eller forskjellige kationiske monomerer samt eventuelt også av ikke-ioniske monomerer, som additiv til hindring av dannelsen, veksten og/eller agglomereringen av gasshydratkrystaller i en blanding av vann og jordolje-/naturgassbestanddeler ved utvinningen eller transporten av jordolje og/eller naturgass.The present invention relates to the use of polymers consisting of one or different anionic monomers and of one or different cationic monomers, and optionally also of nonionic monomers, as additives to inhibit the formation, growth and / or agglomeration of gas hydrate crystals in a mixture of water and petroleum / natural gas constituents in the extraction or transportation of petroleum and / or natural gas.
