Abstract

Fremgangsmåte til å redusere uønskede trykkeffekter nede i en brønn, hvor det nede i borehullet anordnes i det minste ett trykkdempningsapparat (10) som omfatter en iukket trykkavlaster (12)- og et avlastnings-kammer (2, 22, 24), og hvor trykkavlasteren (12) åpnes for å eksponere avlastningskammeret (20, 22, 24) for omgivende fluider som de nevnte uønskede trykkeffekter opptrer i. Trykkavlasteren (12) som inngår i trykk-dempningsapparatet (10) har i det minste én til å begynne med lukket port (16) mens avlastningskammeret (20, 22, 24) danner et fritt volum for dempning av trykk nede i borehullet når den nevnte port (16) på trykkavlasteren (12) blir åpnet.
