| Abstract: | Reservoir reconstruction technology is the core technology to realize the efficient exploitation of low permeability, unconventional oil and gas reservoirs as well as medium and deep geothermal resources. In order to better meet the teaching and scientific research needs of reservoir reconstruction technology, a multi-functional and large-scale true triaxial reservoir transformation experimental device is designed independently. The device innovatively realizes the solid-liquid two-phase pumping in for different sizes of man-made or outcrop cores, different temperatures, confining pressures and pore pressures, and different flow rates of solid-liquid two-phase pumping, as well as reservoir reconstruction and seepage simulation experiments under different wellbore completion conditions. It provides a wealth of evaluation tools such as acoustic emission detection, temperature pressure field and stress-strain field detection and laser scanning measurement after fracturing paragraph. The device has the outstanding characteristics of rich functions, simple operation, safety and high cost performance, which is helpful to build a practical platform for reservoir reconstruction technology innovation, improve the level of teaching and scientific research and promote teachers and students’ innovative development. |
