PATENTKRAV
1. Friktionsreducerende arrangement for et i et borehul placeret rør (14), hvilket friktionsreducerende arrangement omfatter:
en elektrisk aktiveret friktionsreducerende underenhed omfattende:
en strømningsboring (104), som er fluidmæssigt forbundet med en strømningsboring (42) i røret (14), og som forbliver åben for fluidstrømning der igennem under såvel aktiverede som ikke-aktiverede tilstande for den friktionsreducerende underenhed; kendetegnet ved, at det friktionsreducerende arrangement omfatter en friktionsreduktionsenhed (202, 222), som reagerer på en indikation af en blokering af røret (14); hvor friktion imellem røret (14) og omgivende foring (12) eller borehul (10) reduceres i en elektrisk aktiveret tilstand for friktionsreduktionsunderenheden, hvor friktionsreduktionsenheden omfatter en strømningsafbryder (50) til gentagende at blokere og tillade strømning således, at impulsbølger tilvejebringes, hvor strømningsafbryderen (50) er placeret i et ringformet rum (78, 106), som omgiver strømningsboringen (104) i den friktionsreducerende underenhed, eller i en sidelomme (204) i den friktionsreducerende underenhed, eller strækker sig radialt ind i og ud af strømningsboringen (42) i den friktionsreducerende underenhed.
2. I I Claims Nos.:
because they relate to parts of the patent application that do not comply with the prescribed requirements to such an extent that no meaningful search can be carried out, specifically:
2. Friktionsreducerende arrangement ifølge krav 1, hvor den friktionsreducerende enhed yderligere omfatter en elektrisk aktiveret ventil, som tillader adgang til den friktionsreducerende enhed i aktiveret tilstand og blokerer adgang til den friktionsreducerende enhed i den ikke-aktiverede tilstand.
3. Friktionsreducerende arrangement ifølge krav 1, som yderligere omfatter en effektforsyning (46), som elektrisk aktiverer den friktionsreducerende underenhed som reaktion på en indikation af en blokering, hvor effektforsyningen (46) er en effektgenererende underenhed og impulser fra den friktionsreducerende enhed anvendes til at generere effekt i den effektgenererende underenhed.
4. Friktionsreducerende arrangement ifølge krav 1, hvor den friktionsreducerende enhed omfatter en ventil, som blokerer adgang til en del af den friktionsreducerende underenhed i den ikke-aktiverede tilstand og tillader adgang til denne del af den friktionsreducerende underenhed i den aktiverede tilstand.
5. Friktionsreducerende arrangement ifølge krav 1, som yderligere omfatter en føler (28), som detekterer blokeringen af det i hullet placerede rør, hvilken føler tilvejebringer et signal til elektrisk at aktivere den friktionsreducerende enhed.
6. Friktionsreducerende arrangement ifølge krav 5, som yderligere omfatter et registrerende bundhulsarrangement omfattende føleren (28).
7. Fremgangsmåde til reduktion af friktion i et i et borehul placeret rør (14), hvilken fremgangsmåde omfatter:
indsætning af et rør med en strømningsboring i et borehul (10);
detektion af en blokering af røret (14) i borehullet (10);
effektforsyning af en elektrisk aktiveret friktionsreducerende underenhed som reaktion på en detekteret blokering af røret, hvilken friktionsreducerende underenhed har en strømningsboring, som er fluidmæssigt forbundet med strømningsboringen (42) i røret (14) og som forbliver åben for fluidstrømning der igennem under såvel aktiverede som ikke-aktiverede tilstande for den friktionsreducerende underenhed;
kendetegnet ved, at den friktionsreducerende underenhed omfatter en strømningsafbryder (50) til gentagende at blokere og tillade strømning således at impulsbølger tilvejebringes, hvor strømningsafbryderen (50) er placeret i et ringformet rum (78, 106), som omgiver strømningsboringen (42) i den friktionsreducerende underenhed, eller i en sidelomme (204) i den friktionsreducerende underenhed, eller strækker sig radialt ind i og ud af strømningsboringen (42) i den friktionsreducerende underenhed;
og reducerer friktion imellem røret og omgivende borehul i den aktiverede tilstand for den friktionsreducerende underenhed.
8. Fremgangsmåde ifølge krav 7, som yderligere omfatter høstning af energi i en effektgenererende underenhed som et resultat af aktivering af den friktionsreducerende underenhed.
9. Fremgangsmåde ifølge krav 7, hvor tilvejebringelse af impulser inkluderer bevægelse af en ventil til at initiere pulsning.
