1. Overview
Core oil washing is an essential process before core analysis, different core oil content and oil properties are different, the general oil washing method takes 14-30 days, the oil washing efficiency is low, the effect is not ideal. The use of supercritical CO2 strong penetration and efficient separation technology, the use of supercritical CO2 and washing oil solvent together to wash the core oil, can greatly improve the oil washing rate, and the oil washing effect is outstanding. After years of experiments, the oil washing law of different core oil content is finally obtained, which provides convenient conditions for core analysis.
Supercritical CO2 oil washing instrument has the following characteristics:
1. Small size, beautiful appearance
2. Low oil washing cost, short cycle and high efficiency
3. Reasonable structure, simple operation, easy maintenance and repair
4. The core chamber can be customized according to the size of the core to avoid excessive blank volume and waste of energy;
Main technical parameters of 2.
1. Wash oil pressure: ≤ 15MPa
2. Washing oil temperature: RT ~ 85 ℃
3. Core chamber specification: Φ25~120 × 100~250mm
4. Washing oil medium: CO2, alcohol benzene
