FIELD: oil and gas industry.
SUBSTANCE: well production rate is changed and temperature is measured during certain time period for fluid flowing to the well from each layer; temperature variation value ΔTP is measured for initial stage and steady-state value A of temperature-time logarithmic derivative is calculated for each layer. Specific yield value q for each layer is determined against the specified mathematical expression. Yield Q for each layer of the well is determined and influx profile is defined as totality of yields Q for all layers.
EFFECT: improving accuracy of well parameters determination.
