:1998年在孤岛油田中二南、中二中注聚合物区的一些低压注入井开展了聚合物加交联剂注入试验。由试验过程中资料分析发现 ,注入交联聚合物驱油段塞能显著提高油压 ,在增加地下的渗流阻力 ,扩大驱油的波及体积 ,提高采收率方面 ,较单纯的聚合物驱油有独特的优势
: In 1998, a series of injection experiments of polymer and cross-linking agent were carried out in some low-pressure injection wells in Zhongnan and Zhong 2 Middle Polymers in Gudao Oilfield. According to the analysis of the data during the test, it is found that the injection of cross-linked polymer flooding plugs can significantly increase the hydraulic pressure. Compared with the simple polymer flooding, in terms of increasing the seepage resistance of the underground, expanding the flooding volume and enhancing oil recovery, Has a unique advantage
