高温调剖剂研究进展

Research Progress of Heat-Resistant Profile Control Agent

开采稠油的主要方法为蒸汽驱和蒸汽吞吐,但在蒸汽开采过程中,存在蒸汽超覆和汽窜的问题,从而影响蒸汽开发效果。针对该问题,介绍了国内外高温调剖剂的研究进展,主要包括颗粒型堵剂、高温冻胶堵剂、高温泡沫堵剂和其他高温堵剂。综述了各种堵剂的优缺点。

Steam flooding and steam huff-puff were the mean method to recovery heavy oil. However, steam overlay and channeling during the exploitation process had serious influence on development effect. On account of these problems, recent developments of heat-resistant profile agent in heavy oil were presented, including particle blocking agent, heat-resistant gel blocking agent, heat-resistant foam blocking agent and other heat-resistant blocking agent. Their relative merits and disadvantages were summarized.
