Abstract

Production of high-viscosity oil and design of field development systems for such oil is one of the most promising directions in the development of world oil industry. As a rule, oil of this class has pronounced structural–mechanical properties. Nonlinear relationship between the pressure gradient and the rate of oil flow is due to the interaction of high-molecular substances, in particular, asphaltenes and tars that form a plastic structure in it. We have used the analytical model of stationary influx of nonlinear viscoplastic oil to the well bottom in order to provide rationale for the intensifying impact on a reservoir. We have also analyzed the method of periodic heating of a productive reservoir by means of dual-wells. The suggested method of systemic treatment of reservoirs with dual wells can be useful for fields of high-viscosity oil.
