Abstract
Oppfinnelsen angår en fremgangsmåte og anordning for å redusere dagåpningen til en brønn, spesielt for å modifisere en markplassert nedstigningsbrønn (10) med sirkulær dagåpning til en tilsynsbrønn eller spylebrønn. Ved fremgangsmåten dekkes brønnens dagåpning med en dekkplate (12) med en sirkulær åpning (14), som har vesentlig mindre diameter enn brønnens dagåpning. Åpningen i dekkplaten utstyres med en elastisk tetningsring (15) og en brøhnoverdek- ning (18, 20), hvis dagåpning har vesentlig mindre diameter enn brønnens dagåpning, anordnes i den med tetningsringen (15) utstyrte åpning i dekkplaten gjennom at den med en stuss (19) skytes gjennom den for tetningen mellom stussen og åpningens kant anordnede tetningsring, som tillater aksiell forskyvning og awinkling av brønnoverdekningen i forhold til dekkplaten. Anordningen innbefatter dekkplaten (12) og brønnoverdek- ningen (18, 20) med vesentlig mindre dagåpning enn brønnen. Brønnoverdekningen er med en derpå anordnet stuss (19) innført i åpningen (14) i dekkplaten. Mellom åpningens kant og stussen er den elastiske tetningsringen (15) anordnet, som tillater aksiell forskyvning og awinkling av brønnoverdekningen.The invention relates to a method and apparatus for reducing the daytime opening of a well, in particular for modifying a grounded descent well (10) with circular daytime opening to a supervisory or flushing well. In the method, the daytime opening of the well is covered with a cover plate (12) with a circular opening (14), which is substantially smaller in diameter than the daytime opening of the well. The opening in the cover plate is provided with an elastic sealing ring (15) and a well cover (18, 20), the day opening of which is substantially smaller in diameter than the day opening of the well, in the opening provided with the sealing ring (15) by providing it with a bushing (19) is shot through the sealing ring arranged for the seal between the bush and the edge of the opening, which permits axial displacement and angling of the well cover relative to the cover plate. The device includes the cover plate (12) and the well cover (18, 20) with substantially less daytime opening than the well. The well cover is inserted with a sleeve (19) then inserted into the opening (14) in the cover plate. Between the edge of the opening and the bushing, the elastic sealing ring (15) is arranged, which permits axial displacement and angulation of the well cover.
