摘要: 分析了聚合物驱开发效果的影响因素和影响程度,确定了影响因素的分类及权重系数,建立了油藏参数分级评分和权重评分相结合的聚合物驱综合评分计算方法。利用该方法计算了中国13个聚合物驱矿场应用实例的综合化评分。文中采用指数回归方法建立了聚合物驱综合评分与聚合物驱提高采收率的关系,即通过计算油田区块的聚合物驱综合评分来预测聚合物驱开发效果和潜力的方法。应用新方法预测了河南油田古城124和下二门H2II区块聚合物驱提高采收率值,与矿场实际开发效果的误差分别为3.8%和12.7%。新方法考虑影响因素客观、应用便捷,可快速评价油田聚合物驱开发潜力及可行性。

Abstract: By analyzing the influence degree of main factors on polymer flooding effect, the classification and weighting coefficient for each factor were determined. A comprehensive scoring method for polymer flooding was established with consideration of reservoir parameter scores and their weighting factors. The comprehensive scores of 13 polymer flooding field tests in China were calculated by the new method. A relationship between EOR and polymer flooding comprehensive score coefficient was built by exponential regression according to the evaluation result of polymer flooding field tests in China. It could be used to predict the development effect of polymer flooding for different reservoir types. It was applied to prediction of the EOR of polymer flooding in Gucheng 124 Block and Xiaermen H2II Block. The errors between the predicted results and actual values were 3.8% and 12.7% respectively. It was objective and convenient to calculate the polymer flooding potential and evaluate the polymer flooding feasibility in the fields.

Key words: polymer flooding, predicting method, weight coefficient, potential, comprehensive evaluation
