The new unlimited-stage full-bore sliding sleeve staged fracturing technology is based on the conventional casing isolation sliding sleeve staged fracturing completion string, and uses a full-bore sliding sleeve and soluble fracturing balls of the same size for staged fracturing.
The matching design of the sleeve and the chuck eliminates the ball injection level difference, and can achieve unlimited-level fracturing, and the fracturing scale is not limited.
The fracturing operation is continuous and efficient. After each section of fracturing, the balls and chucks are put in, and the fracturing construction of the next section can be transferred after the sleeve is opened.
The casing wellbore realizes large-diameter and low-resistance production, and the chuck can be fished out with tools with continuous tubing in the later stage to achieve full-diameter.
