Parameter determination of the method of directional unloading of the reservoir based on physical modelling on a true triaxial loading setup

The article presents a theoretical and experimental substantiation of the method directional unloading reservoir in fields with low-permeability reservoirs. relevance is due to reduction hydrocarbon resources modern conditions need create new efficient environmentally friendly technologies develop deposits hard-to-recover reserves, primarily results study stress-strain state vicinity well, both cased open, are presented. They necessary programs for laboratory testing core specimens from studied fields. A technique physical modelling deformation processes bottomhole zone decrease pressure at well bottom true triaxial loading unit described order determine parameters process impact on formation reservoir, leading an increase productivity. was applied Verkhneviluchanskoye oil gas condensate field southwest Republic Sakha (Yakutia). Expe-rimental studies were carried out unique scientific loading, created IPMech RAS, Triaxial Independent Loading Test System. adapted field, successful application determined: design, drawdown values permeability zone.
