Investigation of Thermodynamic Processes During Multiphase Fluid Filtration to the Horozontal Well in Heterogeneity Reservoir

In this paper, we presented the models of non-isothermal one-phase and two-phase inflow to horizontal well. It was illustrated that such models can be used for NIT of wells to estimate the properties of the near-wellbore zone which has low permeability compared with all other parts of reservoir. We analysed influences of the main effects which affect the wellbore temperature: two-directional Joule-Thomson effect, heat absorbtion caused by phase transitions. We summarize the results into the table of appropriate model choice to correct interpretation of NIT for a few types of completion and a few values of gas-oil ratio in some synthetic case.
