摘要

In this paper, new models of numerical simulation of non-isothermal multiphase inflow to the well are introduced. These models take into account a damaged near-wellbore zone with low permeability, perforation channels. With the models, it is investigated an opportunity of near-wellbore zone characterization and estimation its parameters (radius, permeability) based on the study of non-stationary downhole temperature and pressure data. Main factors of uncertainty are determined, their influence on the estimated parameters is analyzed.
