引言交联聚合物凝胶是一种由疏水聚合物和交联剂形成的以分子间交联为主、分子内交联为辅的三维网络结构的凝胶体系。在实际堵水应用中,低浓度疏水聚合物与交联剂在地面混合配制好后,从油井注入地层。在配制体系和注入地层时,由于受到地面管线、注入泵以及油藏孔隙介质的剪切速率较大,可能会影响注入的交联聚合物凝胶的反应过程。同时,疏水 Introduction Crosslinked polymer gel is a kind of gel system formed by hydrophobic polymer and cross-linking agent, which is mainly composed of intermolecular cross-links and complemented by intramolecular cross-links. In practical plugging applications, low concentrations of hydrophobic polymer and cross-linking agent in the ground after mixing prepared, injected into the formation from the well. During formulation and injection into the formation, the reaction of the injected crosslinked polymer gel may be affected by the relatively high shear rate of the surface pipeline, injection pump, and reservoir pore media. At the same time, hydrophobic
