Abstract

The invention relates to the technical field of oil reservoir numerical simulation application and oil reservoir recovery efficiency improvement, in particular to an oil reservoir injection and production optimization method and device, a storage medium and electronic equipment, and solves the problem that in the prior art, the oil reservoir production efficiency cannot be accurately evaluated under the influence of the characteristics of a temperature-sensitive composite profile control and displacement system. According to the method, the change rule of the viscosity after the temperature-sensitive plugging agent component exists in each grid block is represented through a relation model of the water phase viscosity, the concentration of the temperature-sensitive plugging agent component and the temperature change, and the chemical relation model of the water-soluble viscosity reducer component in the water phase and the original component in the oil phase represents the chemical viscosity reduction process. The change rule of the permeability curve is corrected by the relation model of the change of the oil phase relative permeability curve along with the improvement of the capillary number, the dynamic change of reservoir physical property and fluid rheological property parameters of each grid in each iterative calculation is updated, and oil reservoir injection and production are optimized according to the obtained second water phase relative permeability and second oil phase relative permeability.

Description

technical field [0001] The application relates to the application of reservoir numerical simulation and the technical field of optimizing reservoir injection and production, in particular to a method, device, storage medium and electronic equipment for optimizing reservoir injection and production. Background technique [0002] At present, reservoir numerical simulation technology is the most important means to evaluate the effect of a certain oilfield development mode. However, in the reservoir numerical simulation software developed at home and abroad, there are generally only mature chemical flooding numerical simulation methods for polymer flooding, surfactant flooding, ASP flooding, etc. These methods generally assume that the reservoir is at a constant temperature during the chemical flooding process. The influence of the state (reservoir temperature) or temperature change on the chemical flooding within a certain range is negligible, but laboratory experiments show th...
