FIELD: oil industry. SUBSTANCE: first independent networks of holes positioned one under another are drilled in two pools different by kinds of oil: upper pool saturated with high viscosity oil and lower pool saturated with low-viscosity oil. Both pools are drilled with opening of lower pool. In production wells using upper pool with high-viscosity oil part of lower pool saturated with low-viscosity oil is perforated. Then samples of mixtures of oils in these wells are taken. Perforated thickness of lower pool h is found by formula, where Qis discharge of oil well of upper pool saturated with high-viscosity oil, cu.m/s; μ is viscosity of oil in pool conditions of lower pool, Pa.s; Ris radius of supply contour, m; ris filtration resistance taking into account imperfection of well by character of opening of lower pool, d.e; K is penetrability of lower pool, sq, m; ΔP is depression on lower pool, Pa. EFFECT: increased efficiency of process thanks to intensification of working of pool saturated with high-viscosity oil. |
