Claims (11)
1. Fremgangsmåde til boring og udførelse af en brønd, hvilken fremgangsmåde omfatter: udførelse af følgende trin a) - e) i én enkelt gang for en borestreng ind i en brøndboring (12): a) boring af en sektion af boringen (12); b) placering af en perforeret kappe (48) i sektionen af brøndboringen (12); c) fastgørelse af den perforerede kappe (48) ved indstilling af en holder (50), og kendetegnet ved, at fremgangsmåden omfatter følgende trin: d) tilbagetrækning af borestrengen fra kappen og e) derefter isolering af sektionen af brøndboringen (12) fra resten af brøndboringen (12) vertikalt over sektionen af brøndboringen (12).
2. Fremgangsmåde ifølge krav 1, hvor trin a) - e) udføres, mens sektionen af brøndboringen (12) er eksponeret for et tryk, der er mindre end en fuld væskesøjle, der strækker sig til et overfladested (30).
3. Fremgangsmåde ifølge krav 1, hvor trin a) - e) udføres, mens sektionen af brøndboringen (12) er eksponeret for en tofasevæskesøjle (56).
4. Fremgangsmåde ifølge krav 1, hvor indstilling af holderen (50) endvidere omfatter ekspansion af holderen (50).
5. Fremgangsmåde ifølge krav 1, hvor isolering af sektionen af brøndboringen (12) endvidere omfatter montering af en stopanordning (52) i en foringsstreng (42), der indbefatter holderen (50) og den perforerede kappe (48).
6. Fremgangsmåde ifølge krav 5, hvilken fremgangsmåde endvidere omfatter gruspakning af sektionen af brøndboringen (12), hvilket trin med gruspakning omfatter: fjernelse af stopanordningen (52), placering af en sandstyringsenhed (64) i foringsstrengen (42), og strømning af en grus- (78) opslæmning ind i en ring (22) mellem sandstyringsenheden (84) og sektionen af brøndboringen (12).
7. Fremgangsmåde ifølge krav 6, hvor gruspakning af sektionen af boringen udføres i et enkelt trin af en arbejdsstreng (76) ind i brøndboringen.
8. Fremgangsmåde ifølge krav 6, hvilken fremgangsmåde endvidere omfatter montering med grus af en injektionsforing (58) i en brøndindkapsling (46), og strømning af en gas (60) ind i brøndindkapslingen (46) gennem et ringformet rum (62) mellem injektionsforingen og brøndindkapslingen (46).
9. Fremgangsmåde ifølge krav 8, hvor montering af injektionsforingen (58) udføres efter isolering af sektionen af brøndboringen (12) og før gruspakning af sektionen af brøndboringen (12).
10. Fremgangsmåde ifølge krav 8, hvor montering af injektionsforingen (58) udføres før boring af sektionen af brøndboringen (12).
11. Fremgangsmåde ifølge krav 1, hvor boring af sektionen af brøndboringen (12) endvidere omfatter rotation af et borehoved (16) forbundet med den perforerede kappe (48).
