Title

Theory and Methods for Multi-Scale, Multi-Modal, and Multi-Field Coupling Numerical Simulation of Unconventional and Fracture-Vug Carbonate Oil-Gas Reservoirs

Abstract

The oil-gas flow mechanics in unconventional and fracture-vug carbonate reservoirs is characterized by multi-scale, multi-modal, and multi-field coupling features, making its flow behavior and numerical simulation exceptionally complex. From a deep mechanical theoretical perspective, this study proposes an overall research framework involving multi-scale characterization of flow mechanisms, cross-scale correlation, multi-physical-field coupling modeling, and unified description of continuous-discrete media, forming a new research paradigm for modern oil-gas flow and numerical simulation.

Key Achievements:

1. Pioneering Digital Rock Technology: Based on artificial intelligence methods, we have developed innovative techniques for constructing multi-scale, multi-mineral shale digital rock cores and pore network models, and flow simulation methods,  enabling precise acquisition of pore structure, permeability, relative permeability curves, and capillary pressure curves.

2. Advanced Numerical Simulation Methods: We created multi-modal, multi-field coupling numerical simulation methods and technologies for complex hydrocarbon reservoirs that account for micro-scale flow mechanisms. This includes the development of large-scale parallel numerical simulation software, with key performance indicators—such as simulation grids (10 billion), computation speed, and discrete fracture-vug processing capacity (100,000 fractures)—significantly surpassing current commercial software.

3. Machine Learning-Driven Optimization: We established methods for 3D development production optimization and fracture parameter inversion in complex hydrocarbon reservoirs using machine learning, enhancing the engineering application efficiency, reliability, and practicality of numerical simulation.
