&lt;p&gt;This article presents the field pilot tests results related to cyclical gel polymer flooding technology as applied under the conditions productive reservoirs rich in high-viscosity oils (viscosity in reservoir conditions above 300 mPa • s) of the Buzachi North oil field, extending the boundaries of application of these methods. The work used the methods of hydrodynamic modeling, mathematical analysis; the necessary parameters of fractures and «super reservoirs» for calculating the working volumes of the injected compositions were estimated using tracer studies.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>High-viscosity oil</kwd><kwd>non-uniform permeability</kwd><kwd>water breakthrough</kwd><kwd>fissuration</kwd><kwd>super reservoirs</kwd><kwd>gel polymer flooding</kwd><kwd>fissure isolation</kwd><kwd>profile log alignment</kwd><kwd>high-viscosity gels</kwd><kwd>displacement ratio</kwd><kwd>ASP (alkaline/surfactant/polymer)</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>тұтқырлығы жоғары мұнай</kwd><kwd>өткізгіштігі жоғары гетерогенділік</kwd><kwd>су серпілісі</kwd><kwd>жарықшақтық</kwd><kwd>суперколлектор</kwd><kwd>гель-полимерлі суландыру</kwd><kwd>жарықтарды оқшаулау</kwd><kwd>қабылдау профилін теңестіру</kwd><kwd>тұтқырлығы жоғары гельдер</kwd><kwd>ығысу коэффициенті</kwd><kwd>ASP</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>высоковязкая нефть</kwd><kwd>проницаемостная неоднородность</kwd><kwd>прорывы воды</kwd><kwd>трещиноватость</kwd><kwd>суперколлектор</kwd><kwd>гелеполимерное заводнение</kwd><kwd>изоляция трещин</kwd><kwd>выравнивание профиля приемистости</kwd><kwd>высоковязкие гели</kwd><kwd>коэффициент вытеснения</kwd><kwd>ASP</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Телин А.Г., Латыпов А.Р., Гусаков В.Н.
