Abstract
En fremgangsmåte er tilveiebrakt for å hemme dannelse, agglomerering og tilstopping med gasshydrater i et fluid inneholdende hydratdannende bestanddeler. Fremgangsmåten er spesielt nyttig i olje- og gassindustrien i boring, produksjon og brønnstrømtransport. Fremgangsmåten medfører tilsetning til hydratdannende fluider av et additiv, idet nevnte additiv A omfatter en eller flere amidforbindelser omfattende en eller flere av de følgende grupper 0 R, R2 hvor RI og R2 uavhengig er valgt fra gruppene omfattende hydrogen eller organiske grupper som har 1 - 5 karbonatomer, men det totale antall av karbonatomene i RI og Rj må ikke overstige 7, og RI og RZ kan være forbundet med hverandre under dannelse av en 5-7 leddet ring og kan inneholde O-, N-, S-, P-, Si-atomer i ringen. Additivet kan anvendes sammen med andre komponenter så som korrosjons- og kjelestensinhibitorer som innvirker på effekten av additivet som en gasshydratinhibitor. En fremgangsmåte er også tilveiebrakt for å redusere stabiliteten av emulsjoner dannet fra hydratdannende fluider og additiv A, ved tilsetning av et andre additiv B.A process is provided to inhibit formation, agglomeration and clogging with gas hydrates in a fluid containing hydrate-forming constituents. The method is particularly useful in the oil and gas industry in drilling, production and well flow transport. The process involves the addition to hydrate-forming fluids of an additive, said additive A comprising one or more amide compounds comprising one or more of the following groups 0R, R2, where R1 and R2 are independently selected from the groups comprising hydrogen or organic groups having 1 to 5 carbon atoms, but the total number of carbon atoms in R 1 and R 2 must not exceed 7, and R 1 and R 2 may be interconnected to form a 5-7 membered ring and may contain O-, N-, S-, P-, Si atoms in the ring. The additive can be used with other components such as corrosion and pebble inhibitors which affect the effect of the additive as a gas hydrate inhibitor. A process is also provided to reduce the stability of emulsions formed from hydrate-forming fluids and additive A, by the addition of a second additive B.
