Abstract
Inflow performance relationship (IPR) is one of the effective methods for describing oil feeding capacity of wells, also important basic data needed for determining and selecting lifting modes and working systems. On the basis of productivity predicted under the conditions of single phase flow and 2 phase flow of oil and gas, a new method is put forward for determining the integral IPR curve of 3 phase flow of oil, gas and water in nonflowing wells, field application demonstrates that the method is feasible.
