The article describes the stage of building a PVT-model, required for building an integrated model of a field. The process of PVT-model building is described step by step, methods of the model adaptation and parameters, by means of which convergence of the model data and results of laboratory studies of deep samples was achieved, are described. The process of creating pseudo-components in the range from C7 to C16+ is described to improve the consistency of the results of modeling and actual studies. The obtained values of viscosity, oil density, saturation pressure, volume factor and gas solubility achieved during PVT-modeling are compared with the averaged values of the deep samples indicators. Two PVT-models based on the results of deep samples study, taken during the first and fourth stages of a field development are compared. According to the results of the comparison, the conclusions are made that in future when building models of wells and surface networks it is necessary to use the PVT-model built on the basis of deep samples selected at the late stage of development.
