Abstract

En fremgangsmåte for sentralisering av rør før. sementering og etterfølgende ekspansjon involverer bruk av en flerhet av teleskoperende sylindere hvis fremre eller bakre ende er lukket, og som føres frem av påført innvendig trykk i røret eller mekaniske midler. Røret ekspanderes fra sitt indre med de sylindriske teleskoperende elementer fremdeles ført frem. Sementen skyves på grunn av sentraliseirngsenhetene helt rundt røret. Etter at sementen er levert skyver ekspansjonen av røret de teleskoperende elementer inn i borehullets vegg.A procedure for centralizing pipes before. cementing and subsequent expansion involves the use of a plurality of telescoping cylinders whose front or rear ends are closed, and which are advanced by applied internal pressure in the pipe or mechanical means. The tube is expanded from its interior with the cylindrical telescoping elements still advanced. Due to the centralizing units, the cement is pushed all the way around the pipe. After the cement is delivered, the expansion of the pipe pushes the telescoping elements into the borehole wall.
