Method for implementing drilling, involves carrying out drilling in axial direction through drilling channel provided in partition wall, where over-pressure area for drilling is adjoined

摘要

The method involves carrying out drilling in an axial direction (X) through a drilling channel (3). The drilling channel is provided in a partition wall (4), where an over-pressure area is adjoined for drilling. A drilling head is introduced with subsequent linkage in the drilling channel, where an annular space is designed between the drilling head and the linkage or wall of the drilling channel. An independent claim is included for a device for implementing a drilling.
