如果基质渗透率较低，因其吸渗排油速度低，不宜采用较高的采油速度。
But if matrix permeability is low, higher recovery rate is not allowed to use due to its low imbibition displacement velocity.
提出了一种新的流动系数取值方法，能够准确描述停注过程中毛管力作用引起的吸渗现象。
A new method is established to determine flow coefficient which can well describe the imbibition phenomenon due to the action of capillary force.
对这一过程建立方程描述并求解，结果显示了化学浆液在孔隙系统中的吸渗速度远小于在裂隙系统中的流动速度。
The equation of the process is raised and calculated. The results show that the flow rate of chemical grout in fracture system is much less than that in porous system.
