AI Technical Summary
Existing chip models fail to simultaneously consider the strong heterogeneous structure, heterogeneous wettability, and matrix fracture depth differences of marl-laminated layered shale, resulting in inaccurate and incomplete simulation results.
A chip for simulating shale fracturing, seepage, and extraction is designed, including an overlapping substrate and cover plate, with etched main channels, secondary fractures, and pore throat structures. The chip combines limestone and mudstone layers to simulate the region, taking into account heterogeneous wettability and fracture depth differences, and is equipped with image acquisition, temperature regulation, pressure regulation, and vacuum generation devices for accurate simulation.
It achieves accurate and comprehensive simulation of the shale fracturing, seepage, and injection processes, providing high-precision data support and enabling observation of fluid flow behavior and changes in oil occurrence state.
