交联聚合物冻胶是目前国内外应用最广泛的调剖堵水剂，在现场应用过程中，其效果受到多种因素的综合影响。本文综述了机械剪切、多孔介质剪切和吸附、pH值、岩性等多种因素对动态成胶过程的影响，同时为多孔介质交联聚合物动态成胶的进一步研究方向提出了建议。

Cross-linked polymer gel was the most widely used profile control and water shutoff agent. The gelling condition was conclusively influenced by a series of factors. In this paper, a plenty of research achievements were integrated. Influencing factors on dynamic gelling process such as mechanical shear, porous media shear action, absorption, pH value, lithology character were discussed. And further research direction of dynamic gelling of cross-linked polymer in porous media was proposed.
