| contents | The fracturing-flooding technology is a new process for the development of low-permeability oil reservoirs, achieving a series of successful applications in oilfield production. However, existing numerical simulation methods for pressure drive struggle to efficiently and accurately simulate the dynamic changes in reservoir properties during the fracturing-flooding process, particularly the expansion and closure of fractures within the reservoir. This paper introduces a Darcy flow model with dual-porous and dual-permeable characteristics based on seepage mechanics theory, utilizing two sets of rock stress-sensitive parameter tables to describe the physical property changes of the matrix and fractures during the fracturing-flooding process. Different parameters are set for the X and Y directions to characterize the anisotropic features of the reservoir. A numerical simulation method aimed at dynamic analysis of fracturing-flooding is established, along with an automatic history fitting method based on the CMA-ES algorithm to derive rock mechanics parameters that align with actual block conditions. |
