摘要：水驱转注聚合物经济时机是影响聚合物驱开发效果和经济效益的重要因素。在国内外关于经济评价模型和界限研究成果的基础上，从聚合物驱与水驱经济评价参数和方法的特点出发，建立了聚合物驱与水驱增量开发经济效益对比的两种模型。应用指标相关性分析方法，确定了影响水驱转注聚合物驱开发经济效益的因素，通过设计不同条件下的方案组并进行评价，形成了相应的界限图版，给出了大庆油田二类油层注聚合物潜力区块
不同油价、不同单井控制地质储量、不同含水率以及不同老井利用率条件下的提高采收率界限。关键调：聚合物驱；注聚时机；效益对比；经济界限；增量经济模型

Abstract: The opportunity of transferring into the polymer injection from the water flooding is the important factor of influencing the development effects and economic benefits of the polymer flooding. On the bases of the study a-chievements of the economic evaluating model and limits at home and abroad, from the viewpoints of the character-istics of the economic evaluating parameters and methods of the polymer and water floodings, two kinds of the mod-els were established for the economic benefits contrast of the incremental development between the polymer flooding and water flooding. With the help of the analyzing method of the index correlation, the influencing factors were de-termined on the development economic benefits of the transferred polymer flooding from the water flooding, by means of designing and evaluating the scheme group under different conditions, the corresponding chart boards of the limits were mapped, and furthermore the EOR limits were presented for the potential blocks of the polymer-in-jected secondary oil layers in Daqing Oilfield under the conditions of the different oil prices, different individual well controlled OOIPs, different water cuts and different used rates of the old wells.
Key words: polymer flooding; polymer injection opportunity; benefit comparison; economic boundary/limit; in-cremental economic model
