METHOD OF CONTROL OF OIL DEPOSITS DEVELOPMENT BY WATER- FLOODING

摘要

FIELD: oil-producing industry. SUBSTANCE: method includes periodic injection of polymer solution and suspension of dispersed particles in polymer aqueous solution. In so doing, suspension of other dispersed particles in polymer aqueous solution is additionally injected. Polymer aqueous solution is used in the form of solution with viscosity comparable with viscosity of formation oil. Proposed method is used for control of oil deposits by water-flooding ensuring equalization of injectivity profile of injection wells, restriction of inflow of formation water and increase in coverage of formation by water-flooding. EFFECT: provision of possibility of control of oil deposit development. 2 cl
