FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil industry and aims at oil-field management. To determine hydrodynamically unbounded sites, formation pressure, formation fluid viscosity, relative permeability of oil and water are measured; pressure pattern maps and filtration and permeability rate pattern maps are plotted; the pressure pattern maps are overlaid on the filtration and permeability rate pattern maps. The desirability function of advanced recovery methods (ARM) is calculated for each site by a multidimensional equation of its dependence on a number of producing and injection wells, permeability, layer and zone nonuniformity, depletion of reserves, watering, fluid discharge of the site. For the hydrodynamically unbounded sites with equal desirability function, water emulsion (WE) stability is additionally measured in each well with calculating an average WE stability within each site and recommending applying the ARM on sites to increase the WE stability. For a specific well, the ARM application is recommended to ensure and stabilise the maximum WE stability. ^ EFFECT: method allows in equal average desirability function on the hydrodynamically unbounded sites, to choose the sites to apply the ARM taking into account effect of the recovery methods; more effective management ensured by more complete list of the parameters characterising a field being developed ^ 2 cl, 2 dwg |
