Abstract
Mud is fed to a distal end of the string (2) in a bore hole in the earth. Each time the string (2) has been displaced into the litosphere over a predetermined distance, a connecting cycle is started. This cycle includes the steps of: connecting one mud head (15, 16) of a mud circulation structure to a pipe section (1) to be connected; disconnecting another mud head (15, 16) from the pipe string (2); and subsequently connecting the pipe section (1) connected to the mud head (15, 16) to the pipe string (2). During a next connection cycle, the other mud head (15, 16) is connected to a next pipe section (1) to be connected. The time during which the mud structure is disconnected from the pipe string (2) is substantially reduced. A device for carrying out that method and a drilling rig including such a device are also described.
