Abstract

Anordning (10) og fremgangsmåte til prøving av en uforet brønn (12) og for frembringelse av en fluidumprøve fra denne. Anordningen (10) omfatter en kompresjonspakning (22) på et borerør (20). På borerøret (20) er det anordnet et hus (30) med et svingekammer (32) og en lukkeventil (28) i forbindelse med svingekammeret (32). En prøvetager (36) for fluidum står i forbindelse med svingekammeret (32). Under bruk blir pakningen (22) bragt i en tilsatt stilling ved vektbelastning. Lukkeventilen (28) er trykkstyrt slik at fluidum kan strømme fra en formasjon (18) elelr sone av interesse inn i svingekammeret (32) og deretter inn i prøvetageren (36). Ved å åpne en ventil (34) i huset ved en ende av svingekammeret (32) kan formasjonsfluidum drives tilbake i formasjonen (18) eller sonen av interesse med en bull-heading-operasjon. I en foretrukket utførelse kan pakningen (22) og borerøret (20) kobles fra det øvre av anordningen (10) og pakningen (22) kan bores ut.
