FIELD: oil producing industry. SUBSTANCE: method includes dilution of high- viscosity oil with low-viscosity oil by lifting high-viscosity oil with the help of bottom-hole oil pump. Simultaneously, low-viscosity oil is supplied to well. First, well with low-viscosity oil is operated. Low- viscosity oil is supplied to drill-string-borehole annular space of nonoperative well with high-viscosity oil to obtain output from this well of mixture of high-viscosity and low-viscosity oil. Then, well with high- viscosity oil is operated. EFFECT: reduced expenditures and higher efficiency of recovery of high-viscosity oil under complicated conditions. 1 dwg
