Apparatus for preventing hole erosion effects during fracturing and use thereof

Abstract

The application provides a device for preventing the hole erosion effect in a fracturing process and application thereof, and belongs to the field of oil and gas exploitation.The device comprises an upper sheath and a lower sheath connected in sequence, a nozzle is installed on the wall of the lower sheath, the inner cavities of the upper sheath and the lower sheath are communicated, a rotating mechanism is installed in the inner cavity, the rotating mechanism can drive the lower sheath to rotate around the central axis, a pumping mechanism is also installed in the inner cavity, and the pumping mechanism can deliver a spraying agent to the nozzle.The application has the advantages of reasonable design, simplicity, high efficiency, improved hole anti-erosion effect, and improved efficiency and reliability of the fracturing construction.The application effectively avoids the mortar erosion to the hole in the fracturing construction process, greatly relieves the adverse effects caused by the hole expansion on the balanced extension of the cracks, and improves the volume fracturing reconstruction effect.
