The productionpressuredifferential can be increased and the injection-production ratio can be reduced by transferring from flowing to pumping.
利用自喷转抽提液方法，放大生产压差，降低注采比。

Production performance, pressure field and saturation field are measured with a differential pressure unit and saturation measuring probes.
用模型上布置的压差传感器和饱和度测量探针，测量了聚合物驱的开采效果、压力场和饱和度场变化。
