Abstract

Det er tilveiebrakt en fremgangsmåte for å ta prøver av en flerfasefluidstrøm, som omfatter følgende trinn: å ta prøver med en prøvetakingssonde, av en del av fluidstrømmen; å måle gjennomstrømningsmengden til prøvetakingsdelen; og å måle, uavhengig av prøvetakingstrinnet, den totale gjennomstrømningsmengden av fluidstrømmen, hvor gjennomstrømningsmengden av prøvetakingsandelen blir regulert i henhold til forholdet mellom gjennomstrømningsmengden til prøvetakingsandelen og gjennomstrømningsmengden til fluidstrømmen, for å oppnå hovedsakelig isokinetisk prøvetaking av fluidstrømmen. Fremgangsmåten kan tilveiebringe isokinetisk prøvetaking innenfor en nøyaktighet på 5 % eller mindre, og fortrinnvis bare prøver ved en liten andel av fluidstrømmen. Fremgangsmåten er spesielt egnet for gasskondensatbrønner med høy gjennom strømningsmengde. Et tilsvarende prøvetakingssystem er tilveiebrakt, som spesielt er egnet for prøvetaking av en strømning fra brønnhoder. En strømningsforbehandlingsanordning for bruk med prøvetakingsfremgangs-måtene og systemene er også tilveiebrakt, idet strømningsforbehandlingsanordningen er en rørseksjon som innbefatter en virvelinduserende seksjon, en strømningsutjevner og en strupeskive.
