Abstract

Et styresystem omfattende to styrerør (13, 15) blir senket i en brønn med et lederør (11). Styrerørene (13, 15) er sammenbundet med skiller (17) som deler lederøret i to halvdeler. Hvert skille (17) omfatter to symmetriske halvdeler som vender i motsatte retninger. Operatøren senker en borerørstreng (25) i lederøret for å bore en først brenn med liten diameter ved bunnen av lederøret. Etter boring til den ønskede dybden senker operatøren en første fdringsrørstreng (29) ned i lederøret og gjennom det nye brønnhullet. Foringsrøret (29, 31) blir plassert på en side av hvert skille (17) og sementert på plass. Deretter senker operatøren borerøret ned gjennom den andre siden av skillene (17) og gjentar boringen og bekledningen med f6ringsrør (31) av en andre brønn.
