FIELD: oil and gas production industry, particularly to develop oil field where several reservoirs having different permeability are jointly developed.
SUBSTANCE: method involves determining perforation orifice density; injecting working agent into reservoirs or interlayers through injection wells and producing oil from reservoirs or interlayers through production wells. Basic reservoir or interlayer characterized by lesser oil flowability is selected and perforation orifice density is determined for above reservoir or interlayer from mathematical formula taking into consideration oil flowability. Perforation orifice density for remainder reservoirs or interlayers is determined from mathematical formula, which does not take into consideration oil flowability. Basic reservoir or interlayer, as well as remainder reservoirs or interlayers are perforated with the use of single-type perforator.
EFFECT: increased oil recovery.
