采用ＸＣＴ图象分析技术以研究双重介质的砂岩裂缝和孔隙度，对于稳产开采石油是很有价值的。ＸＣＴ法测量双重介质孔隙度的优越性在于利用图象分析技术可以分别给出裂缝和砂岩的孔隙度，它同称重方法和核孔隙计测量的数据对比，是一种精度高，直观，无损伤的实验技术。ＸＣＴ测量双重介质孔隙度可给出孔隙度的分布，这有利于了解和预测残余油的分布 The use of X-CT image analysis technology to study the dual medium sandstone cracks and porosity, for the steady production of oil is of great value. The superiority of X-CT in measuring porosity of dual media lies in the fact that the porosity of fractures and sandstones can be given separately using image analysis techniques. Comparing with the data of the weighing method and the nuclear porosity meter, it is an accurate and intuitive , No damage to the experimental technology. X-CT measurement of porosity in dual media gives the distribution of porosity, which is useful for understanding and predicting the distribution of residual oil
