摘要

System for opening a window in a column casing positioned in a well bore and method for opening a window in a column casing positioned in a well bore. A system to open a window in a column of coating (42) positioned in a bore hole casing (32). It is provided.The system includes a hydraulic pressure intensifier (116) having a housing and a set of pistons with a differential area piston. The set of pistons is longitudinally displaceable relative to the housing and is initially fixed in relation to the same to prevent longitudinal movement between the same.A set of anchors (114) is operable to arrest lengthwise the hydraulic pressure intensifier (116) in the column of coating (42).A tool for opening window (118) operavelmente associated with the hydraulic pressure intensifier (116) is operavelmente plug-in in the column of coating (42) such that when the set of anchors (114) is longitudinally fixed in the column of coating (42) and the set of IP Stu00f5es is not fixed with relation to the accommodation of the hydrostatic pressure.The longitudinal movement of the set of pistons transmits a force to the tool opening window (118) thus opening the window in the column of coating (42).
