Abstract
In this paper presents the results of calculating pressure using such models of multiphase flow in a gas-condensate wellbore as Gray, No Slip and Beggs-Brill. Algorithms for calculating the properties of condensate and reservoir gas without / taking into account phase transitions are described. Comparison of the results of numerical pressure calculations based on models performed in the RN-VEGA software package with their analogues in the Saphir software module of the Ecrin from Kappa Eng., showed best convergence (the relative difference is not more than 0,5 %). A matrix of applicability of models that best predict pressure depending on the values of water-gas and condensate-gas factors according to field data has been obtained.
Materials and methods
In this work, the boundari es of the values of the water-gas and condensate-gas factors will be determined, at which the pressure along the gas-condensate wellbore is calculated using multiphase flow models with a permissible deviation based on field data.
Keywords
