摘　　要：采用RS 1 50流变仪研究了聚丙烯酰胺和黄胞胶类弱冻胶的流变性 ,并采用不同介质填砂管模型研究了弱冻胶在多孔介质中的渗流机理以及水、油等流体在冻胶充填介质中的流动规律 ,得出水、油等流体在本体冻胶中的渗流特性不满足达西定律。The rheological properties of polyarylamide and weak gel (belongs to xanthan gum) is studied by using RS-150 rheometer. The percolation flow mechanism of weak gel in porous medium and flow rule of the fluid (such as water, oil) in gel packing medium is studied by using sand packed tube model of different media. We draw a conclusion that fluid (water, oil) rheological properties in entity gel is not in conformity with Darcy Law, and the relationship between flow resistance and velocity is exponential relation.
