同理，对于双螺杆泵，粘度大的流体比粘度小的液体的泄漏要小，泄漏量与介质粘度有一定的比例关系。
Similarly, for the twin-screw pump, the fluid viscosity smaller than the viscosity of the liquid leakage is smaller, leakage volume and viscosity of a certain percentage of media relations.
MD 1膜驱剂的加入不增加驱替流体的粘度，不改变油水流度比，膜驱油机理与聚合物驱不同。
Moreover, the viscosity of water didn't increase due to the addition of MD-1, and no changes of its oil-water current ratio was observed.
