ESTIMATION OF NON-STATIONARY FLOODING APPLICATION
Background Enhanced Oil Rtcovery methods are usually based on wider stimulation of productive strata by various modifications of flooding. In recent years, the well stream watering intensifies, which results in lower power efficiency of oil production and lower efficiency of deposit development, in total. In this regard, there is an urgent need to increase the rate of oil recovery from reservoirs, with reduction of the volume of produced water and intensification of operation of producing well stock. Aims and Objectives Develop approaches to planning effective stimulation of oil deposits using the technology of non-stationary flooding, and enhanced oil recovery with decreased well stream watering and intensification of oil production. Results To estimate the efficiency of non-stationary flooding in combination with the flow regulating and flow diverting technologies, simplified models of the reservoirs under study have been developed. In order to enhance oil recovery and intensify oil inflow from the reservoir it is recommended to use a complex of technologies. Conclusion Complex technologies of oil and gas deposit stimulation using non-stationary flooding that are aimed both at higher oil recovery ratio and at limited water movement within the producing reservoir, and simultaneous stimulating treatment of the bottom-hole zone will allow significantly higher efficiency of the field development.
