Abstract
A differentiated real-time injection-production optimization adjustment method of an intelligent injection-production linkage device belongs to the field of oil reservoir injection-production technologies. The method includes: initializing networks; building an injection-production environment model; by an agent, reading an initial state of an injection-production environment; writing a file by an injection-production policy network; obtaining state data of the moment t+1; reading a next state and an economic net present value within the time step; assigning the next state to the current state until a to-be-optimized production period is completed; by batch training on the model, updating a parameter of the environment agent model; updating a parameter of the action evaluation network and a parameter of the injection-production policy network; repeating the above steps until an optimal model is obtained; based on the stored optimal model, linking the intelligent injection-production device to obtain state information of the oil reservoir.
