Abstract

Det er beskrevet en elektrisk oppvarmingsanordning (10) for formasjonsvarmebehandling i brønnhull innen området for olje- og gassproduksjon. Vanneanordningen (10) inne- holder et separat koblingskammer (12), vamiekammer (16) og kjølekammer (14), Idet sistnevnte befinner seg mellom koblingskammeret (12) og varmekammeret (16). Varmebehandlingen utføres ved å føre varmeapparatet (10) inn i et borehull som skal behandles. En gass, fortrinnsvis nitrogen eller lutt, bringes til varmeapparatet ved hjelp av en slange eller et rør (24). Gassen passerer gjennom koblingskammeret (12) og kjølekammeret (14), og blir varmet opp ved å følge en buktet bane i varmekammeret (16) før den støtes ut fra varmeapparatet (10).
