Abstract: FIELD: oil producing industry, particular, methods for development of oil deposits with high-viscosity oils. SUBSTANCE: method for development of oil deposits includes drilling of wells of complicated profile. Vertical part of well is introduced into the upper part of producing formation. Then, well is drilled parallel to producing formation. The next stage of well is drilled below the previous one but also parallel to producing formation. Upper and lower stages of each well are located in same vertical plane. In this case, each stage of any well is used alternately as injection and producing. Injection of heat carrier and oil withdrawal from each well is performed simultaneously. The lower stage of well when heat carrier is injected heats the formation and oil is withdrawn from the upper stage of this or other well. In case of injection of heat carrier into the upper stages of the well, formation is heated in the given vertical plane and oil is withdrawn from the lower stages of the well, both, of this and other one.
