新型聚合物溶液粘度稳定剂研究

Study of A Novel Polymer Solution as Viscosity Stabilizer

随着注水开发的深入 ,孤东油田有些区块综合含水急剧上升 ,为了提高油田最终采收率 ,达到控水稳油的效果 ,对综合含水高的区块开展了三次采油试验 ,对油层注入聚合物开发 ,但聚合物溶液在配制及注入过程中粘度会降低。为了增加聚合物注入粘度 ,提高聚合物驱油效果 ,研制了一种不含重金属的粘度稳定剂Ⅰ型和含有机铬的粘度稳定剂Ⅱ型 ,并对其增粘和稳粘效果进行了考察。

With a deepening of water flooding technology, water content in some reservoirs of Gudong Field increases dramatically. A novel polymer solution was injected in tertiary oil recovery test to improve final oil recovery. This novel polymer is viscosity stabilizer without heavy metal but containing organic chromium. The result shows that it can increase and maintain the viscosity in flooding system, thus improve the effect of polymer flooding.
