A New Approach to IPR Curves of Horizontal Wells in Two-Phase Reservoirs

摘要

The inflow performance of 31 theoretical solution-gas-drive reservoirs was simulated. The reservoirs contained a wide range of rock and fluid properties, relative permeability characteristics, and the wells were assigned with various skin effects. Two types of inflow performance relationships (IPRs) were developed from about 13,500 data points. The first type, using traditional IPR nomenclature, represents normalized pressure versus the normalized oil flow rate from a horizontal well to its maximum flow rate which is allowed to be damaged. The second relates normalized pressure with the ratio of the flow rate to the maximum theoretical, undamaged flow rate.
