摘要: The invention relates to a method for completing a borehole (1, 2) prior to the start of production, wherein after making the borehole (1, 2) the borehole wall (3) is anchored in a sealed manner with a conveying tube (4) and/or casing tube, and the borehole wall (3) is perforated with perforation units (5) at desired points. To complete a borehole without the use of cemented conveying tubes and/or casing tubes, it is proposed that the conveying tube (3) and/or casing tube be provided on its outer surface with a swellable sealing jacket (6), wherein the sealing jacket (6) swells after activation and anchors the annular gap between the conveying tube (4) and/or casing tube and the borehole wall (3) in a sealed manner and simultaneously centres the conveying tube (4) and/or casing tube in the borehole (1, 2).
