  • Simulation experimental system and method for real-time optimization and adjustment of smart oilfield injection production
    Patent number: 12031412
    Abstract: A system for real-time optimization and adjustment of smart oilfield injection production includes a closed rectangular reservoir simulation box, a reservoir 3D-printed physical model, a simulation production horizontal wellbore system, a simulation injection horizontal wellbore system, a fluid supply system, a fluid collection system, a power fluid system and a computer data collection and control system. The reservoir 3D-printed physical model is in the closed rectangular reservoir simulation box. The simulation production horizontal wellbore system and the simulation injection horizontal wellbore system are in the reservoir 3D-printed physical model. The fluid supply system injects a displacement fluid into the simulation injection horizontal wellbore system in the reservoir 3D-printed physical model to flow to the simulation production horizontal wellbore system.

  • INJECTION-PRODUCTION RELATIONSHIP OPTIMIZATION METHOD BASED ON HETEROGENEOUS FLOW FIELD CHARACTERIZATION
    Publication number: 20220229959
    Abstract: The present invention relates to an injection-production relationship optimization method based on heterogeneous flow field characterization. The method comprises the steps of: first, calculating a density of a flow field by adopting a method of converting a linear density into a dot density; then, calculating an intensity of the flow field by adopting an analytic hierarchy process; and performing flow field characterization by utilizing mathematical methods such as PCA dimensionality reduction and clustering and calculating a product of flow line densities and intensities of flow fields in different regions of the flow field, and performing optimization for a goal of minimizing a variance of the product in combination of an genetic algorithm to solve the optimum injection-production quantity as an optimum solution (the optimum injection-production quantity) that enables the flow field to be displaced in a balanced manner.
