摘要
本文介绍利用淀粉和丙烯酰胺单体的接枝共聚体系以及膨润土堵剂,开发出了一种具有很好的封堵能力,价格低廉的有机——无机复合1凝胶调剖堵剂。研究了该调剖剂各组分的浓度对成胶时间及凝胶强度的影响,并采用填砂管模拟试验方法对该调剖剂的注入性能以及成胶后的封堵效果进行了尝试性的评价。实验结果表明,该调堵剂具有较好的注入性能和较高的封堵强度,且成胶时间可调,耐盐,成本较低。
Organic-inorganic composite gel profile control agent with strong plugging capacity and the lower price is developed,through the use of starch and acrylamide-grafting copolymerization and bentonite clay.The effect of every compositional concentration on gelation time and gel intensity is studied.Injection efficiency of profile control agent and plugging effect of gelation are evaluated,using simulation method of sand filling tube.The experimental results show that this kind of profile control agent has bett...
