The fracturing technology of hydraulic sand blasting perforation is a new well stimulation technology integrating perforation, fracturing and isolation into one. It uses a jet tool with a nipple to generate high-velocity fluid, which will pass through the casing and rocks and create holes in the formation. Then, the high-velocity fluid acts directly on the bottom of the holes, generates pressure higher than the formation fracturing pressure and finally creates a single crack in the formation.

◆ Characteristics 

- It integrates perforation, fracturing and isolation into one; 

- No packer; 

- Multi-stage fracturing with one-trip string; 

- It can improve the construction efficiency and safety, and reduce damages and costs.
