| 摘 要： | 为使室内实验结果更好地为油田现场提供指导,应用相似理论中的相似定数法导出聚合物驱相似准则,按照因变关系将相似准则分为因变相似和自变相似。利用数值模拟方法对各自变相似准则进行敏感性分析,同时利用相似第二定理研究聚合物驱采出程度数学模型,计算结果表明聚合物驱阶段采出程度同自变相似准则之间满足乘积关系,由此建立聚驱阶段采出程度数学模型,同时引入相渗校正系数修正室内实验模型与现场模型之间的相渗差异,实践表明,该方法准确可靠,能够满足现场预测要求。

| Abstract: | In order to apply physical simulation results to oil fields properly and provide theoretic direction for the oilfield development,similar equation analysis method is used to get the similarity criterion of polymer flooding reservoir,similarity criterion is divided into dependent criterion and independent criterion according to variable relation,taking recovery of polymer flooding as example,numerical simulation is used,sensitivity analysis is carried out for the similarity criterion,and the Second Theorem is used to study the mathematical model of the recovery of polymer flooding.The results show that there exists a multiplication relationship between the recovery polymer flooding reservoir and the similarity criterion.Based on this relationship,the recovery model of polymer flooding is established,in which the relative permeability coefficient is applied to modify model.physical simulation is consistent with the numerical simulation,the model can meet the requirement of the actual oilfields. |
