Productivity Prediction Method for Fractured Wells in Extra-Low Permeability Oil Reservoirs

摘要：

Inflow performance relationship (IPR) is the foundation of optimal designing for operation parameters of oil wells.A prediction method is proposed for evaluating the inflow performance relationship of fractured wells in extra-low permeability-deformed media oil reservoirs.Specifically, an elliptic flow mathematical model is constructed in the situation that the well inflow performance of fractured well are divided into two parts in which the seepage flow from oil layer goes to the fracture and seepage flow from fracture heads to bottom-hole.Additionally, the changes of the permeability and fluid viscosity with pressure are taken into account.The feasibility of the above method is shown by an application example.
