This paper introduces the model of a fluid influx to the hydraulic fractures that are perpendicular to the wellbore and suggests the formula to calculate the flow rate of a horizontal well with a multi-stage fracturing depending on the fractures number. The authors have been starting out from the well-known method for calculating the flow rate of a vertical well with a hydraulic fracture length much less than the drainage radius. At the same time the calculations ignored the effect of configuration of injection wells towards the producing horizontal well with multi-stage fracturing, assuming that the formation pressure remains constant at the external reservoir boundary.
