INCREASE OF TECHNOLOGICAL EFFICIENCY OF CARBONATE RESERVOIRS DEVELOPMENT IN UDMURTIA USING CYCLIC FLOODING

 

Annotation. The reason of low efficiency of the system of stationary water flooding at the Vereya-Bashkirian site of one of the fields of the Udmurt Republic is the heterogeneity of filtration-capacitance properties of reservoirs and placement of wells in zones of increased fracturing. Non-uniformity of oil displacement front with water leads to high water cut of extracted products and non-involvement of low-permeability layers into development due to heterogeneity of formations in permeability. The method of cyclic flooding as an effective technology for increasing reservoir pressure and oil recovery is considered. Involvement of low-permeability reservoirs, previously not covered by waterflooding, is achieved by creating unsteady pressure drops by changing the mode of operation of injection wells. Calculations on the hydrodynamic model of the Vereya-Bashkirian object have shown that the technology demonstrates greater efficiency than stationary injection.

Keywords: cyclic flooding, heterogeneity of productive formations, low reservoir pressure, residual reserves.
