Spontaneous imbibition refers to the process of absorption with no pressure driving the phase into the rock. 自發(fā)吸滲指不用壓力將潤(rùn)濕相驅(qū)進(jìn)巖石的過程。 www.infopetro.com.cn
The capillary pressure curve is important for understanding saturation distribution in the reservoir and affects imbibition and multiphase fluid flow through the rock. 毛細(xì)管壓力影響多相流體流經(jīng)巖石和毛細(xì)運(yùn)移。 www.infopetro.com.cn
The wettability index of rock surfaces under a given condition, WR, was determined quantitatively from the pseudo capillary pressure curve measured in the process of imbibition. 由自嘆過程中所測(cè)得的擬毛管壓力曲線，可定量確定巖石表面在某一特定條件下的潤(rùn)濕指數(shù)（WR）。
