FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil and gas industry, to development of oil pools, related to surface-doming, and can be used at a final stage of oil fields operations. The essence of the invention is as follows: the method includes boring of pressure and producing wells, pumping of a working agent through pressure wells, oil extraction through producing wells, and selection of surface doming sections exceeding absolute marks of the bed. At that in wells, located at the tops of surface doming, the watered part of the stricken payout bed is cut off with a packer and isolated by means of a chemical reagent and/or a backfill solution, which is allowed to harden. Then the additional striking of the payout bed is performed above the packer but below the upper boundary of the payout bed. After that the said wells are used as producing, the rest wells, hydrodynamic connected with the said wells within the boundaries of the said payout bed, are transferred into pressure wells, and a working agent is pumped into them. ^ EFFECT: reduction of material and financial costs at the implementation of the method with increased efficiency of oil-pool development. ^ 2 dwg |
