摘　　要：高含水期聚合物驱开发单元增油量是聚合物驱产油量与水驱基础产量之差额 ,如何确定聚合物驱产油量是增油效果评价和经济评价的关键 .采用数模预测方法计算聚合物驱产油量与实际生产结果有一定差距 ,且调整起来费时费力 .通过比较多种方法 ,提出了“三阶段”预测聚合物驱产油量的模型方法 ,即产量上升阶段、峰值稳定阶段和产量递减阶段预测模型 .此方法具有准确、简便的特点 ,在河南油田The amount of oil production increased by polymer flooding is the difference between the oil production obtained by polymer flooding and by traditional water flooding. Calculating the oil production obtained by polymer flooding is the key to the evaluation o f development effect and economic benefit of polymer flooding. There is difference between the results calculated by numerical simulation and practical results in Henan Oilfield. For this reason, a 'three stage prediction model' is put forward. In the model, the production process of polymer flooding is divided into three stages: production rising stage, production stabilizing stage and production descending stage. The application results of the prediction method to three blocks in Henan Oilfield show that it is easy and accurate, and the predicted results tally well with practical results.
