- 摘要：
- FIELD: oil-and-gas industry.SUBSTANCE: group of inventions relates to methods of preparation and treatment for well stimulation. The method of preparation of branch holes includes drilling of multiple branch holes from a vertical well. A selective injection deflector with pass-through for tubing between each respective pair of branch holes is installed. Hydraulic fracturing of multiple branch holes within one completion run by means of consecutive isolation of branch holes from multiple branch holes and supply of hydraulic fracturing fluid medium to each consistently isolated branch hole during lowering are performed.EFFECT: improvement of efficiency of hydraulic fracturing of branch holes without lifting of equipment.9 cl, 37 dwg
