Abstract

Fremgangsmåte og anordning for å lette tilbakevending til sidegrenen med kveilrør som unngår søk- og finn-metoder. En føring som henger fra kveilrøret er utstyrt med en orienteringsmekanisme slik at føringen orienteres riktig i forhold til den opprinnelige ledekilepakning, og derved frembringer en awiks- flate for kveilrøret i ønsket retning for sidegrenen. Det skraverte område kan dreie uavhengig. ML-ankeret vil virke til å orientere den kabelførte kveilrør- innføringsanordningen med vinduet. Når kveil- rør-bunnhullstrengen er orientert, kan den inn- føres i sidegrenen. Der- som innføringsanordningen skulle bli fastkjørt, kan kveilrør-bunnhullstrengen gjenvinnes ved å avskjære pinnene i topp-rørstykket, topp-rørstykket vil komme ut med CT-verktøyene. Den nedre del av innførings- anordningen kan fiskes opp ved hjelp av et fiskeverk- tøy. Innføringsanordningen kan være 30' lang for å ta hensyn til kveilrør- bunnhullstrengen. Ut- sperring med vindu kan oppnås ved å tilføye avstands-rørstykker under innføringsanordningen.Method and apparatus for facilitating return to the side branch with coiled tubes avoiding search and find methods. A guide hanging from the coiled tubing is provided with an orientation mechanism such that the guide is oriented properly with respect to the original guide wedge gasket, thereby providing a winding surface for the coiled tubing in the desired direction for the side branch. The shaded area can rotate independently. The ML anchor will act to orient the wired coiled tube insertion device with the window. When the coiled tubing bottom hole string is oriented, it can be inserted into the side branch. Where the insertion device is jammed, the coiled tubing bottom hole string can be recovered by cutting off the pins in the top tube piece, the top tube piece will come out with the CT tools. The lower part of the insertion device can be fished up using a fishing tool. The insertion device may be 30 'long to account for the coiled tubing bottom hole string. Window locking can be achieved by adding spacer pieces under the insertion device.
