孤东油田六区东南部、西北部注聚区分别有12口、11口注入井先后于2005年12月12日、2006年3月30日开始添加交联剂,方案设计添加交联剂分别为193t、81.8t。根据以往经验由于现场所用聚合物性能的不稳定、交联剂的不配伍以及现场添加设备的因素,交联效果有时不理想,为此连续开展了聚合物与交联剂的室内交联实验并用于指导现场添加,有效的提高了现场交联效果,本文详细介绍了室内实验的过程和现场添加的效果,对今后类似的交联聚合物驱具有一定指导意义。
There are 12 injection wells in the southeastern and northwestern parts of Gudong 6 oilfield, 11 injection wells respectively on December 12, 2005 and March 30, 2006 to add cross-linking agent. For 193t, 81.8t. According to past experience due to the instability of the polymer used in the field, the incompatibility of cross-linking agent and the factors of adding equipment in the field, the cross-linking effect is sometimes unsatisfactory. Therefore, the cross-linking experiment of polymer and cross-linking agent Add in the guidance site, effectively improve the effect of cross-linking site, this article describes in detail the indoor experiment process and the effect of added field, the future of similar cross-linked polymer flooding has some guidance.
