摘要
提出了一种确定油层内部油水系统与岩石之间润湿角的方法。对同一岩样分别用离心法和压汞法测定其毛管压力曲线,据此分别计算平均孔径,最后利用同一岩样其平均孔径相等的原则求得润湿角。
This paper has presented a new procedure to determine the wetting contact angle of oil/water/rock system According to the approach, the capillary pressure curve of the same sample is measured by the centrifugal method and the mercury-injection method, respectively The formula for calculating the average pore radii can derived through the two capillary pressure curves separately. The wetting contact angle can be obtained according to the principle that the average pore radius of the same sample is equivelent.
