Shear & Lock Fracturing Sleeve

The shear & lock fracturing sleeve is used as the first stage fracturing sleeve that could be sheared open at an accurate pressure value. The tool is run above the flow collar with sleeves closed, the string could be circulated. After the setting ball is dropped and the packers are all set, further pressuring up on the tubing would snap the shear pins to open the sleeve, then fracturing pumping could be initiated.

The sleeve has an internal lock design that once it is open by differential pressure, it could not be pushed back, which eliminates the risk of sleeve closing during fracturing.

The activating force could be adjusted by replacing shear pins. Alloy steel is used by default and anti-corrosion materials could be selected as an option.
