On hydrogeological calculations of flowing wells at abrupt decrease of their flow rates

The article considers the method of hydro geological calculation of wells at abrupt decrease of their flow rates as a result of injecting in them additional hydraulic resistance. Based on the previously carried out individual investigations, the authors present the analytic relation for determining the value of the resistance that ensures the target value of the well flow rate.The suggested relation enables staged automatic control of the flowing well operation.The article ascertains the applicability of Theis equation for determining the value of partial recovery of the head after abrupt decrease of the well flow rate. At that it is accepted that at the given point there is concurrently operating virtual injection well with constant rate, at the value equal to the diminished one.
