Annotation:
The creation of an integrated model of the Shah Deniz offshore gas condensate field with combined wells, being a priority for LUKOIL PJSC, is of great interest. The creation of this model is associated with a number of complex features such as the fluid type (gas condensate) complexity, presence of wells with joint operation of several development objects where there is uncertainty with the PVT-properties of the fluid produced. Due to these facts, the standard approaches to modeling the field are not applicable. The article considers the development and testing the method to be applied for increasing the quality of the created integrated model by means of developing the fluid compositional model and the method application of PVT-models mixing, using the equations of the state, equilibrium, material balance and components distribution in phases with conserving the energy and mass of wells operating several development objects. The mixing is performed on the basis of the data, obtained in the course of fields geophysical survey and describes the multiphase flow behavior of the under- and above-ground production systems, as well as fixes the actual behavior of a gas condensate field.
