摘要
为了减少模拟参数,提高运算速度和精度,推导了烃源岩中油、气、水三相流体共同渗流时的分流方程,建立了石油初次运移史的两相渗流模型。应用泥岩压汞资料作出了含水饱和度与油、水相对渗透率之间的关系曲线,并确定出石油开始从泥岩中排出的临界含水饱和度为1.03%。最后以海参1井为例加以说明,得出了其石油初次运移史和运移效率。
In order to decrease the modcrease the modelling parameters and to increase the
computing velocity and precision, a filtration equation of gas, oil and water in source
rock was deduced, and a two-phase filtration of petroleum primary migration model
was established. The curve of the relative permeabilities of oil and water vs. water satu-
ration was gotten using forcing mercury information of shale. The determined critical oil
saturation of primary migration is 1. 03%. Finally, the petroleum primary migration
history and migration efficiency of Well Haican-1 were modelled.
