聚合物驱不同阶段动态调整技术的研究与应用

Study on dynamic adjustment techniques in the different stages of polymer flooding and its application

根据聚合物驱见效特征 ,将聚合物驱过程划分为见效初期、见效高峰期和递减期 3个阶段 .对各阶段所要采用的动态调整技术进行了研究 。

The factors of influencing polymer flooding result have reservoir characteristics, type of well pattern, rate of polymer flooding, viscosity of polymer, rate o f production etc. To a given block of polymer flooding, the rationality of injection production relation is the key to the result of polymer flooding. According to the display characteristics of polymer flooding, polymer flooding development process is classified into three stages: initial stage of effectiveness, peak stage of effectiveness and descending stage of effectiveness. The dynamic adjustment of every stage is studied. The experience got here here can be used for reference in the polymer flooding of other oilfieds.
