The paper presents the results of researches on the specification of clay components, as well as the zones of intra- and interstratal fluid flows in the formation processes of oil-gas fields.

The investigations have been carried out in the context of Sangachal-Duvanny-Khara-Zira (SDKhZ) field, located in Baku archipelago of South Caspian basin (SCB).

It was defined that the presence of clayey chlidolite in the reservoirs are observed more effective in the values of permeability rates.

The zones of intra- and interstrata of fluid flows in the reservoirs were specified based on the lithological model of productive horizons. Therefore, the presence of closed migration-flow (drainage) system both within productive horizons and in the scale of reviewed field was supposed.

In support of these assumptions, 2D and 3D variation models of flow zones indicator values for intrastrata levels of productive horizons and for the section fragment of SDKhZ field have been developed.
