发明名称 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 #CMT# #/CMT# 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. #CMT# : #/CMT# An independent claim is included for a device for implementing a drilling. #CMT#USE : #/CMT# Method for implementing a drilling. #CMT#ADVANTAGE : #/CMT# The 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, and hence ensures to implement a drilling between different areas and different pressures in a significant manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a drilling channel without drilling device. 1,2 : Areas 3 : Drilling channel 4 : Partition wall 15 : Tubing case X : Axial direction.
