Abstract

Foreliggende oppfinnelse angår en fremgangsmåte og en anordning for å bestemme at en borestreng (17) l en brønnboring (29) er utsatt for fastkjøring mot en flate i brønnboringen. Når den er kjennetegnet som en fremgangsmåte, innbefatter fremgangsmåtetrinnene (1) overvåkning av en vibrasjonskarakterlstikk for borestrengen (17) under boreoperasjoner, og (2) sammenligning av vibrasjonskarakteristikken med minst en tidligere vibrasjonskarakteristlkk for å påvise forestående fastkjøring. I den foretrukne utførelse blir vlbrasjonsamplltuden overvåket for å påvise fall l amplitude, noe som angir forestående fastkjøring av rør. Vibrasjonsdata blir fortrinnsvis underkastet en stabiliserende slgnalbehandlingsoperasjon som reduserer uheldig innvirkning fra støy og normaliserer data for å lette sammenligning med tidligere tidsperioder. Dataene blir fortrinnsvis gjengitt og vist i et tidsområdeformat for å muliggjøre visuell sammenligning over et valgt tidsintervall.
