Abstract

The application provides a full-bore infinite-level staged fracturing sliding sleeve based on a smart label, which includes a fracturing sliding sleeve and a smart label for opening the fracturing sliding sleeve. The fracturing sliding sleeve is placed into a wellbore with a casing and cementing is performed. Each fracturing sliding sleeve corresponds to a target fracturing stage in the well. The smart label is placed into the casing through a wellhead, and is pumped forwards in the wellbore; the smart label automatically identifies the target fracturing stage, and is clamped and seated in the fracturing sliding sleeve of the target fracturing stage, thus realizes the opening of the fracturing sliding sleeve with the pressure from a pump truck. The opening of the fracturing sliding sleeve of each stage corresponds to a smart label. After all the stages are fractured, the smart labels are completely dissolved in the fracturing fluid.
