The invention belongs to
polymer flooding of a
tertiary oil
recovery technology, in particular to a
polymer flooding
production optimization method and
system based on inter-well
connectivity. According to the
polymer flooding
production optimization method and
system based on the inter-well
connectivity, the primary option is that an oil deposit is simplified into a series of inter-well
connectivity unit bodies, the shunt volume of all well points are obtained through calculation, and an initial
polymer flooding connectivity model is established; then characteristic parameters of the initialpolymer flooding connectivity model are adjusted, and the optimized
polymer flooding connectivity model is generated; and finally constraint conditions are combined, a
polymer flooding optimal controlmodel is set up, and the polymer flooding index when the economic net present value is maximum is solved, and scene injection-production plan design is instructed. According to the polymer flooding
production optimization method and
system based on inter-well connectivity, the connectivity model of polymer flooding production-polymer concentration can be quickly predicted, the actual production data are combined so that historic matching is conducted, the polymer flooding
optimal control model is solved through an optimization
algorithm, adjustment and control of liquid production capacity and polymer injection concentration in each stage can be automatically realized, the
oil production volume is increased, the
economic benefits are improved, and scene injection-production plan design isinstructed.
