FIELD: oil industry, particularly non-uniform reservoir development.
SUBSTANCE: method involves injecting isolation composition namely Portland cement dispersion and water-soluble polymer in well, wherein the components are taken in proportion of 1:(0.01-0.5) in oil-bitumen product, 5-56 parts by weight of Portland cement and water-soluble polymer are taken for 100 parts by volume of said dispersion; injecting aqueous Portland cement solution along with said dispersion, wherein the solution is taken in proportion of (0.1-0.5) per 1 part of said dispersion.
EFFECT: increased efficiency of stacked oil pool development and highly-permeable watered reservoir zones isolation.
