为改善聚合物驱油效果 ,研制了XL系列有机铬交联剂XL 1和XL 2 ,研究了HPAM/XL交联体系的配方 ,对该配方体系的性能进行了评价 ,开展了矿场试验。从室内研究和矿场试验的结果发现 :加入交联剂可有效地、大幅度地提高聚合物溶液的粘度 ,改善聚合物的抗温、抗盐、抗剪切的性能 ,从而提高聚合物驱油的效果 In order to improve the polymer flooding effect, XL series of organic chromium crosslinkers XL 1 and XL 2 were developed. The formulation of HPAM / XL cross-linking system was studied. The performance of the formulation system was evaluated and a field test was carried out. From the results of laboratory research and field tests, it is found that the addition of cross-linking agent can effectively and substantially increase the viscosity of the polymer solution and improve the heat resistance, salt resistance and shear resistance of the polymer, thereby improving the polymer flooding Oil effect
