| 主权项 | 1. A fracturing system for fracturing a formation surrounding a well tubular structure, comprising: a tubular part to be mounted as a part of the well tubular structure, the tubular part being made of metal, an axially-oriented expandable sleeve made of metal, the sleeve having a wall thickness and surrounding the tubular part, a fastening means for connecting the sleeve with the tubular part, and an aperture in the tubular part, wherein the sleeve has a fracture initiating element, the fracture initiating element comprising at least one area of the sleeve having a decreased wall thickness, the at least one area being configured to project laterally outward from the sleeve at least under pressure and burst when the at least one area reaches a predetermined pressure. | ||
