摘要
本文详细介绍了新型凝胶驱油技术及其在油田的应用。通过与常规聚合物驱油技术和堵水技术的对比，论述了该方法优于现有驱油方法的特点；针对胶态分散凝胶的特殊结构，逐一讨论了现有的各种交联剂体系制备胶态分散凝胶的方法。该项技术已有２９例先导试验，成功率为６６％。
In this review article, a novel kind of chemical flooding systems, colloidal dispersion gels (CDGs), is introduced. The advantages and differences of CDG treatments from polymer flood and polymer gel profile modification are pointed out. The composition (various kinds of crosslinkers for polyacrylamides), structure and methods of evaluation of CDGs are discribed in comparison with that of common, bulk polymer gels. The results of 29 pilot tests published in literature are presented briefly.
