摘要
室内研制出了两种新型的解堵剂DA-Ⅰ和DA-Ⅱ,其中DA-Ⅰ为A、B两组分的复配,DA-Ⅱ为C、D、E三组分的复配。通过对聚合物溶液堵塞和聚合物凝胶堵塞中的解堵试验的评价可以看出,它们能很有效地清除聚合物驱地层堵塞和凝胶堵塞物,在一定的地层温度下能完全溶解凝胶,对提高原油采收率有很大的作用。
Two new blocking removers DA-I,DA-II were developed in laboratory,DA-I was made up of compositions A and B,DA-II was made up of compositions C,D and E,blocking removal tests on polymer solution blocking and gel blocking were evaluated.It can be seen from the tests that they can be used for effectively avoiding the blocking in polymer flooding reservoirs and gel blocking materials,and gel can be completely dissolved under formation temperature,it can be effectively used for enhancing oil recovery.
