聚合物冻胶类堵剂在油田堵水中的应用

在油田堵水作业中聚合物类堵剂得到了广泛的应用，美国FOR方案设计中有35％采用聚合物，而其中的60％采用的是冻胶处理；在国内，聚合物冻胶类堵剂在油田八大类堵水体系中也占有较大的比例。文章描述了聚合物冻胶类堵剂在国内外的发展现状，根据聚合物类型的不同对该类冻胶进行分类，并介绍了其作用机理、应用情况、施工工艺以及理论研究情况，其中PI决策技术已经被广泛地用于指导油田调剖作业，最后指出针对深层、高温油藏聚合物冻胶类堵剂仍有广阔的发展前景。

Application of Ploymer Gel Plugging Agent for Water in Water Shutoff in Oil Field

Ploymer gel plugging agent for water is used in water shutoff widely in oil field, 35% of FOR projects are adopted ploymer and 60% of them is gel ia American. In our country it occupies quite a few proportion in eight kinds of plugging agent. The article writes the actuality of plymer gel plugging agent at home and abroad. The classifying ,the mechanism of various agents for water plugging and profile control, their present application in oil field and the theories research are introduced. It is helpful that the PI decision-making technology is used to guide profile control. At last, it presents the development of it in the deep well and high-temperature condition.
