description Et apparat for å tilveiebringe soneisolasjon i et borehull, omfattende flere sammenlåsende tetningselementer med ankerelementer i motsatte ender. Hvert ankerelement griper tett et borehullsrør, mens de sammenlåsende tetningselementer ikke griper noen del av borehullet derimellom. I et eksempel på anvendelse brukes et brønnhode og en smøreanordning anbrakt over borehullet under trykk og en transportørinnretning for å føre utstyr inn brønnhodet. Det første anker, det andre anker og de flere sammenlåsende tetningselementer blir transportert separat inn i borehullet med transportørinnretningen og sammenstilt i rekkefølge i borehullet for å tilveiebringe soneisolasjon. An apparatus for providing zonal isolation in a wellbore includes a plurality of interlocking sealing elements having anchor elements at the opposing ends. Each anchor element sealingly engages a wellbore tubular whereas the interlocking sealing elements do not engage any portion of wellbore therebetween. In one exemplary application utilizes a wellhead and lubricator positioned over a wellbore under pressure and a conveyance device for conveying equipment into the wellhead. The first anchor, the second anchor and the plurality of interlocking sealing elements are separately conveyed into the wellbore with the conveyance device and sequentially assembled in the wellbore to provide zonal isolation.
