Abstract

Fremgangsmåte og anordning ved reversert sirkulerende sementering av et foringsrør i en uforet brønn. Fremgangsmåten omfatter trinnene å (a) installere foringsrøret i den uforede brønn, (b) installere en overflatetetningsinnretning ved en overflateåpning av den uforede brønnen, idet tetningsinnretningen omfatter - et hus, - en foringsrørhenger opphengt i huset, - en seksjon av foringsrørstreng opphengt i foringsrørhengeren og - en bæreplate festet til huset, et ringrom er dannet mellom seksjonen av foringsrørstrengen og huset og en nedre del a huset og bæreplaten samvirker til å hindre kollaps av brønnen ved overflaten, (c) forbinde en seksjon av foringsrørstreng til foringsrøret samt å (d) pumpe sement ned i ringrommet.
