The causes affecting the accuracy of fluid modeling are provided in the article by the example of gas condensate mixturessaturating the Achim deposits of Urengoyskoe oil and gas condensate field. The algorithmis recommended for selecting a sequence of adjusting and calculating procedures allowing obtain adequate models of gas condensate mixtures. The model of formation gas isused for compositional reservoir simulation modeling of the license site of Urengoyskoe oil and gas condensate field.
The algorithm of gas condensate mixture preparation is given. The process of PVT model of formation mixture saturating the Achim deposits is described. Thecompositional modeling results are provided.
The proposed algorithm allowed obtaining a gas condensate mixture model fully characterizing the original formation fluid and its phase performance at various PT conditions.
