FIELD: oil and gas extractive industry.
SUBSTANCE: method includes lowering and mounting tubing string with packer in a well. Fracturing liquid is pumped into tubing string with certain speed and pressure, and hydro-impacts are formed. Before fracturing liquid a deep secondary opening of high-productive bed portion is performed. Column of tubing pipes with tail piece and cone in lower part is performed. Resilient-viscous compound is pumped into well and pushed to position of formed cracks. Fracturing liquid is forced into tubing pipe, while at starting period - at increased speed. Hydraulic impacts are formed by stopping fracturing liquid flow from the surface, and through same well bed products are extracted.
EFFECT: higher oil yield.
