Abstract

En fremgangsmåte for å installere rør (2) i et sideborrehull (4) som strekker seg fra et hovedborrehull (6), hvorved hovedborrehullet er tilveiebragt, i et punkt nedenfor skjæringen mellom hovedborrehullet og sideborrehullet, med en støtteanordning (8), og som innbefatter: Å føre en avbøyningsanordning (10) inn i borrehullet inntil avbøyningsanordningen kommer i kontakt med støtteanordningen, med avbøyningsflaten (12) til avbøyningsanordningen innrettet for å avbøye rør inn i sideborrehullet; og omgi det øvre partiet av avbøyningsanordningen med et langstrakt rørelement (14) som har et forformet vindu (16) i innretning med munningen på sideborrehullet; og tette mellom det langstrakte rørelementet og foringsrøret (18) til hovedborrehullet i en plassering ovenfor krysningen mellom hovedborrehullet og sideborrehullet; og å føre en rørlengde gjennom det langstrakte rørelementet for å bli avbøyd av deflektoranordningen gjennom det forformede vinduet og inn i sideborrehullet.A method of installing pipes (2) in a side bore (4) extending from a main bore (6), the main bore being provided, at a point below the intersection between the main bore and the side bore, with a support device (8), comprising : Inserting a deflection device (10) into the borehole until the deflection device comes into contact with the support device, with the deflection surface (12) of the deflection device arranged to deflect pipes into the side borehole; and surrounding the upper portion of the deflection device with an elongate tubular member (14) having a preformed window (16) in alignment with the mouth of the side drill hole; and sealing between the elongate tubular member and the casing (18) of the main borehole at a location above the junction between the main borehole and the side borehole; and passing a length of pipe through the elongate pipe member to be deflected by the deflector device through the preformed window and into the side drill hole.
