FIELD: oil and gas production.
SUBSTANCE: methods for hydraulic fracturing. The method for hydraulic fracturing according to the first option comprises collecting data on the properties of the formation and the underground wellbore, collecting data on the results of stimulation treatments carried out on the underground wellbore, entering data into the hydraulic fracturing simulator and determining the parameters of the hydraulic fracturing model, selecting a formation treatment process using hydraulic fracturing based on calculations performed in the hydraulic fracturing model taking into account certain parameters, performing formation processing using the hydraulic fracturing method in accordance with the selected process. The method additionally includes adjusting the formation treatment by hydraulic fracturing according to the parameters of injection speed, concentrations of hydraulic fracturing materials, and injection volumes. The method for hydraulic fracturing according to the second option includes collecting data on the properties of the formation and the wellbore, defining a design for processing the formation using hydraulic fracturing, performing processing of the formation using hydraulic fracturing in accordance with the design and monitoring measurement data for each time step, entering data into the hydraulic fracturing simulator and determining parameters fracturing model, automatically adjusting the fracturing design based on measurement data, and continuing the automatic adjustment until fracturing is completed.
EFFECT: increasing the efficiency of formation processing by hydraulic fracturing.
