摘　　要：交联聚合物调驱技术是在聚合物驱技术上发展起来的一种集调剖和驱替于一体的化学驱技术。交联聚合物是采用部分水解聚丙烯酰胺与交联剂按一定浓度比形成的凝胶,在油藏中适应性强。与聚合物对比的实验研究表明,交联聚合物调驱技术在黏度、耐温性、耐盐性、热稳定性、剪切恢复性、残余阻力系数等方面具有明显优势。矿场试验结果表明,交联聚合物调驱技术是一种非常有效的提高采收率技术,具有明显的降水增油效果,应推广使用。Crosslinked polymer profile - control flooding technology is a new chemical flooding technology, which develops from polymer flooding technology. The crosslinked polymer is the gel which forms from partially hydrolyzed polyacrylamide （HPAM） and crosslinker in a certain ratio and is adaptable in multi - reservoirs. The experimental results showed that crosslinked polymer profile -control flooding technology has obviously advantages compared with polymer in viscosity, heat resistance, salt tolerance, heat stability, shear restoration, residual resistance coefficient, etc. Field tests showed that crosslinked polymer profile - control flooding technology is a very efficient E0R technology, which can decrease water content and increase the yield of oil. It is necessary to promote the application in oilfield.
