摘要
为了探索高温高盐油藏提高采收率的方法,拓展聚合物驱的应用领域,对三种生物聚合物黄胞胶进行了增粘性能、耐温性能和抗盐性能的初步筛选。建立了生物聚合物的评价方法,确认了生物聚合物黄胞胶的应用条件,提出了改进建议。结果表明:生物聚合物黄胞胶适合于地层温度小于80℃,地层水矿化度大于20000mg/L的油藏。
In order to study on enhancing oil recovery in the high temperature and high brine reservoir, and in order to widen application range of polymerflooding, the viscosi-fying, heat-resisting and salt-resisting behaviors of three biopolymer xanthan gums have been screened primarily. The evaluation method of biopolymer is established. The applying conditions of biopolymer xanthan gum are determined. The improving suggestion is put forward. The result showed that biopolymer xanthan gum is suitable to the reservoirs with formation temperature less than 80℃ and formation water salinity higher than 20,000mg/L.
