Abstract

Foreliggende oppfinnelse, vedrører en anordning som kan benyttes i forbindelse med olje- og/eller gassbrønner i den hensikt å øke brønnens produksjon. Anordningen omfatter ytre struktur, i hvilken ytre struktur en første og en andre trykkpåvirket belganordning er anordnet i, der den første og andre trykkpåvirkede anordningen gjennom en opplagringsinnretning står i fluidforbindelse med hverandre. Opplagringsinnretningen er fast forbundet innvendig i den ytre struktur, slik at opplagringsinnretningen avgrenser et lukket og et åpent rom for den første og andre trykkpåvirkede anordningen, idet det lukkede rom er fylt med et fluid ander trykk, mens det åpne rom er i fluidforbindelse med et omgivende fluid.The present invention relates to a device which can be used in connection with oil and / or gas wells for the purpose of increasing well production. The device comprises outer structure, in which outer structure a first and a second pressurized bellows device are arranged, in which the first and second pressurized devices through a storage device are in fluid communication with each other. The storage device is firmly connected internally to the outer structure, so that the storage device defines a closed and open space for the first and second pressurized devices, the closed space being filled with a fluid different pressure while the open space being in fluid communication with an ambient fluid.
