摘要(Abstract)：

为进一步扩大聚合物驱工业化应用规模 ,在聚合物驱一次潜力评价的区块中优选出双河油田北块Ⅳ 1— 4层系。利用理想井组模型进行水驱历史拟合及聚合物驱潜力预测的结果表明 ,采用能反映区块纵向非均质性的井组地质模型拟合全区综合含水率、采出程度来预测区块聚合物驱提高采收率潜力的方法是可行且可靠的 ,基本能反映聚合物驱潜力。与利用常规筛选标准进行潜力预测相比 ,利用理想井组模型进行聚合物驱潜力预测方法可以定量预测聚合物驱油效果。经计算 ,双河北块Ⅳ 1— 4层系聚合物驱可提高采收率 10 90 % ,增加可采储量 12 0× 10 4 t。
Shuanghe oilfield has been selected as the first potential evaluation of polymer flooding. In this paper, a ideal well pattern model has been used to match water flooding and predict the potentiality of polymer flooding. The result shows that it is feasible and reliable to use the geological model, which can reflect vertical heterogeneity of the block,fitting overall water cut and recovery percent of reserves to predict the potentiality of enhanced oil recovery by polymer flooding. It is able to quantitatively predict potentiality of polymer flooding, which is consistency with used standard. It is possible that enhanced oil recovery is more than 10 9% and recoverable reserves is more than 120×10 4t after polymer flooding.
