Tight Oil Fracture-Pore Dual-Porosity Media Static-Dynamic Integrated 3D Geological Modeling Method

Tight oil has become a core alternative to conventional global oil and gas resources, and its development effectiveness highly depends on high-precision 3D geological modeling of fracture-pore dual-porosity media. However, static modeling is often limited to geostatistical inversion of well logging and seismic data, frequently neglecting dynamic reservoir flow responses; while production data and bottomhole pressure data are only used for post-modeling validation and fail to deeply participate in the optimization of static parameters. To address this long-standing common issue in tight oil development, this paper proposes a static-dynamic integrated 3D geological modeling method. Compared with traditional methods, the core breakthrough of this approach lies in transforming the relationship between static parameters and dynamic flow patterns from “posterior matching” to “forward verification,” significantly reducing model uncertainty. This research can provide technical support for high-precision modeling in the efficient development of tight oil reservoirs.
