Development of High-Viscosity Oil Deposits by Heat Methods

摘要

A mathematical model has been developed for the two-dimensional problem on the initial stage of development of a high-viscosity oil pool under the action of heat by the technology of pair horizontal wells, and numerical solutions of this problem have been constructed. The heat expended for warming an oil pool, the evolution of the discharge of a well in it, and the change in the mass of the oil withdrawn from the well in the initial period of its operation, where the pool boundaries insignificantly influence the temperature and hydrodynamic fields around the well, were analyzed. The extrapolation of the numerical solutions obtained to longer times made it possible to estimate the efficiency of the method proposed for the recovery of a high-viscosity oil and to determine optimum regimes of heat action on it.
