Abstract

Method and device to increase the feed speed of a drill bit ( 2 ) and its associated drilling device ( 1 ) when drilling through tubulars ( 6, 8, 10 ) located within one another where in the annuli ( 12, 14 ) created between the tubulars ( 6, 8, 10 ) there is located a material or a fluid which in comparison to the pipe wall material is easer to drill, and where the feed speed of the drill bit ( 2 ) is controlled by a pressure fluid regulating valve ( 52 ) which preferably is located close to the drilling device ( 1 ), and where there during the progress of the drill bit ( 2 ) through the annulus ( 12, 14 ) is opened for an influx of pressure fluid in parallel with the pressure fluid regulating valve ( 52 ).
