摘要
该文依据数值模拟计算结果,对于非均质变异系数小于0.72的正韵律油层,概括出了采收率提高值与非均质变异系数及用量关系的简化预测模型。讨论了在相同用量下采收率提高值与注入浓度的关系,并对聚合物的合理注入浓度及用量作出了预测。
<ABSTRACT> Based on the calculation results of numerical simulation, the
simplified predication model between the incremental value of recovery
factor and the variation factor of heterogeneity and injection rate for
positive rhythm reservoirs with variation factor of heterogeneity less than 0.72
is summarized in this paper. The relationship between incremntal value of
recovery factor with injection concentration under the same injection rate
is discussed and the reasonable injection concentration and injection rate is
predicated.
