Abstract

Det er tilveiebragt anordning og fremgangsmåte for å oppnå en sidebrønntilkopling i en underjordisk brønn (12). I en beskrevet utførelse blir det boret en første brønn (12) som krysser en formasjon og så blir det boret en andre brønn (18) gjennom en sidevegg av en rørformet streng (14) som er posisjonert i den første brønnen. Enten før eller etter at den andre brønnen blir boret gir et stabiliserende materiale (20) plassert i et ringformet rom (22) mellom den rørformede strengen og den første brønnen. Det stabiliserende materialet kan også tvinges inn i formasjonen for derved å øke eller bedre egenskapene til formasjonen.A device and method is provided for obtaining a side well connection in an underground well (12). In a described embodiment, a first well (12) is drilled which crosses a formation and then a second well (18) is drilled through a side wall of a tubular string (14) positioned in the first well. Either before or after the second well is drilled provides a stabilizing material (20) located in an annular space (22) between the tubular string and the first well. The stabilizing material may also be forced into the formation, thereby increasing or improving the properties of the formation.
