Key words: formation water, sea water, filtration, reservoir, waterflooding, scaling.
Geochemical interaction process between reservoir, formation and marine waters with reference to oil-gas-condensate deposits on the Yu. Korchagin oilfield is considered relying on the results of the interfaced experimental and mathematical modeling. It is shown the relationship between chemical composition of production water and properties of the reservoir. Possibility of the account of revealed geochemical effects influences on the permeability change of reservoir. The comparative study of production and marine water injection has been presented to prevent scaling process and reservoir damage.
