본문

Petroleum & Porous Medium NMR well-logging technology is used to reservoir evaluation and formation evaluation. NMR technology can acquire abundant formation information, such as flowing liquid content in a formation, porosity, permeability, oil saturation, aperture size and distribution in rock and so on. The advantages of NMR technology is high precision, simple calibration, avoiding influence of slopping, acquiring many parameters in one well-logging.

Geotechnical & Coal mine.

1.LTHP condition for freezing and thawing mechanism analysis

Freezing and thawing mechanism analysis of soil or rock
Rock damage degradation under freezing and thawing condition
Mechanism of natural gas hydrate formation and decomposition

2.HTHP condition for Percolation mechanism analysis

Percolation mechanism analysis
Dynamic and real-time analysis the oil/water saturation and distribution changes in displacement process
Displacement experiment imaging visualization analysis

Visual observation of permafrost melting process

The bright signal is on behalf of the water. With melting process, signal gradually from the outside to the inside, and finally completely melted

High pressure displacement

MnCl2 Solution flooding oil (Water flooding oil) process

1.Red-Yellow-Blue，Signals weaken sequentially

2.Oil signal strength,MnCl2 solution signal weaken

The left is the water flooding process from left to right. Firstly, the oil in left pores is displaced by water. Then displacing water spread to the entire core from the left core with the displacement time longer，until all the oil inside the core is displaced.

Drilling Fluid Analysis

1.Oil content test for drilling fluid
