Abstract: This article introduces a physical model of microscopic network and the technique of model reproduction. Single-layered and transparent, the model can be used to observe directly the movement of fluid in the tiny pores through the microscope. The wettability of the surface of pores in this model is quite stable and can be controlled in 3 states as highly hydrophilic, highly hydrophobic or neutral,with their tri-phase interracial angle controlled at less than 30°, above 160° and around 90° respectively. The proposed technique of model reproduction can guarantee the repeated use of a single model without changing the parameters, and the change of wettability without changing the other parameters, so as to raise the precision of repetitive and comparative experiments. Many problems that can not be solved for lack of reproduction provisions may thus be solved. By applying the above-mentioned technology with equipments developed by the Research Division for measuring the percentage value of every phase of multiphase fluids flowing in the capillaries, many experiments on water-oil flow and multiphase flow have been conducted,
