The Biot-flow and Squirt-flow mechanisms are two important mechanisms of fluid flow in porous media with fluid. Dvorkin and Nur presented an unified BISQ(Biot-Squirt)model,but it is complex in fluid-pressure equation. Maradou S.D and Erwin A.

• Biot流动和喷射流动是含流体多孔隙介质中流体流动的二种重要力学机制,Dvorkin和Nur提出了同时包含Biot流动和喷射流动力学机制的统一的BISQ(Biot-Squirt)模型。
