| 摘 要： | 以聚丙烯酰胺为主剂，用无机铬和有机醛作交联剂，分别制备了低浓度交联调剖体系，确定了其最佳配方。双岩心并联模拟封堵试验结果表明，此低浓度调剖体系即能封堵高渗层，又启动低渗层，可以有效堵塞大孔道，扩大后续水驱的波及体积，提高采收率。

| Abstract: | A low concentration crosslinking agent and profile control agent system was prepared with polyaerylamide as the main agent and inorganic chrome and organic aldehyde as the crosslinking agent respectively, and the optimum formulation for the low concentration crosslinking agent and profile control agent system was identified. The results of double - core parallel plugging simulation experiment have shown that this low con- centration crosslinking agent and profile control agent system can not only plug high permeability reservoir, but start low permeability reservoir, and therefore it can plug big channels and expand the water flooding swept volume, leading to the increase of recovery factor. |
