MODELING OF WATER REGULATION IN WELLS WITH WATERED PRODUCTION IN HETEROGENEOUS OIL FORMATIONS

Summary: At a certain stage of oil and gas production, by increasing the efficiency of regulating water volumes in wells with water-cut production, it is possible to reduce water cut and increase current oil recovery. When developing oil fields, in order to maintain reservoir pressure and increase the oil recovery factor, water or various additives are pumped into the objects. During some stages of oil field development, various types of water (including water injected into the reservoir and external water filtered from the top) enter highly permeable areas and reach the production wells, and the amount of water in their products increases. In this regard, the main problem is the isolation of water entering the well by maintaining oil production. The presented work describes the development of nanostructured gels that easily penetrate into the water-saturated depth of the formation in flooded wells, effectively blocking culverts, without changing the phase permeability of oil, mathematical modeling of the process, and analysis of the results.
