Basic Parameters:
- Magnet: permanent magnet 0.3±0.05T
- Probe: Ø150mm
Applications:
1. Exploration and development of low permeability oil field
- Movable fluid saturation determination
- Pore size distribution of rock
- Mechanism of oil displacement
- Cracks and micro-cracks evaluation
- Mechanism of fracturing process
2. Exploration and development of Gas field
- The influence of overburden pressure on porosity and permeability
- Pore size distribution of rock
- Mechanism of water flooding
- Gas field caverns, cracks and micro-cracks evaluation
- Studies on modification mechanism
- Free/irreducible fluid saturation
3. Exploration and development of CBM(Coal Bed Methane)
- Porosity
- Pore size distribution
- Fracture development
- Water saturation determination
These MR images show that water go into the rock core from left side and water displace the oil process.
