Abstract

Physico-chemical control of filtration flows in the formation is considered to be a promising method to enhance oil recovery in oil fields developed by flooding. The methods increasing conformance by the injected fluid (water and gas) have been found to be the most effective in West Siberia. At a later stage of flooding physico-chemical control of filtration flows in heterogeneous reservoirs is carried out by selective isolation, i.e. blocking of well drainaged and highly permeable zones, causing the drowing of producing wells. It is convenient to employ gels with controled generation time [1, 2].
