Abstract

In the paper on example of Guneshli field the South-Caspian basin the character of spatial changes of lithofacial parameters of the main oil-gas reservoir in Azerbaijan — productive series (Early Pliocene) has been considered. These studies were based on analysis of thin sections of different stratigraphic complexes of the productive series, the data of geophysical studies of the wells and as well as 3D geological modeling. Significant lithofacial changeability of productive series has been revealed both in section and in area that is explained by features of paleo-geographic conditions of sedimentation in early Pliocene and participation of various sources of feed of the basin with sediments. Dependence of initial yields of wells on spatial heterogeneity of permeability of reservoir rocks has also been established. It is established that spatial heterogeneity of lithofacial and reservoir properties of rocks controls their oil saturation and well productivity.
