This device utilizes manual simulation technology and modern microcomputer program computing technology to collect, record, calculate, and process various data in real-time, avoiding heavy data recording and calculation. It is convenient and fast. With this device, the following experiments can be conducted:

1. Measurement of fluid permeability;

2. Research on improving oil recovery rates, such as water flooding and chemical flooding (using coagulants, polymers, and ternary composite flooding);

3. Geological sensitivity evaluation;

4. Research on oil extraction technology, acidification, water plugging, and profile control;

5. Evaluation of the effects of drilling fluid and completion fluid on rock cores through reverse displacement and series fluid contact tests;
