FIELD: oil and gas production. ^ SUBSTANCE: procedure for development of non-uniform oil reservoir consists in pumping into reservoir the first fringe - dispersion of components, and in pumping the second fringe - water solution of polymer and salt of polyvalent metal. Also as a dispersion of components there is used the dispersion of high dispersed water-repellent material - HDWRM at amount of 0.1-3.0 wt % in medium and at least one silicon containing substance. The said water solution of polymer is acidated to pH 1-3 and additionally contains at least one surface active substance SAS at the following ratio of components, wt %: polymer 0.01-5.0, at least one SAS 0.1-3.0, salt of polyvalent metal 0.01-0.3, water - the rest. ^ EFFECT: increased efficiency of method of reservoir treatment due to improved rheological and water-repellent properties of compositions pumped into reservoir and due to enhancing their oil displacing properties. ^ 4 cl, 6 tbl, 5 ex |
