RESEARCH OF CHANGING THE FLUID FILTRATION DIRECTION IMPACT ON RECOVERY EFFICIENCY FROM HIGH-VISCOSITY OIL DEPOSITS

 

Annotation. For many oil-bearing fields in the Ural-Volga region, which are confined to terrigenous deposits of the Lower Carboniferous sediments of the Visean stage of the Lower Carboniferous there is a problem of outrunning watering of production wells over the recovery of oil reserves. It is explained by layer and zonal heterogeneity of reservoirs, as well as high oil viscosity. In case of fields with high-viscosity oil, the exploitation system often does not provide sufficient reservoir pressure maintaining due to circulation of injected water through the watered zones. Undrained oil reserves can be involved into filtration process by creating flooding centers which provide change in the direction of fluid filtration flows and increasing of pressure gradients at the displacement front. As a result, the coverage efficiency and, consequently, the final oil recovery factor are increased, and the field lifetime is shortened.

Keywords: change in the direction of filtration flows, maintaining reservoir pressure, oil field of Urals-Volga region, high-viscosity oil, water cut, coverage efficiency, oil recovery.
