Theoretical Studies Of Inflow Relationship And Forecasting Method For Low Permeability Reservoir

Studies of inflow relationship aimed at characteristic of low permeability reservoir have great significance for its development and management. Based on flow principle and the characteristic of low permeability, this paper made a deep study of IPR forecasting method. Based on the flow equation concerned on threshold pressure gradient and deforming media, this paper productivity equation and IPR forecasting method for low permeability reservoir. Error analysis when Vogel equation was applied to low permeability was presented in this paper, we also derived productivity equation and IPR curve for double phase flow.Aimed at the vertical fractured well in low permeability, based on the pressure response forecasting method presented by Cinco-ley, this paper shows a method of IPR and productivity forecasting, we also analyzed the sensitive factors for IPR curve of a vertical fractured well.
