摘要
聚合物驱油的采收率与油藏聚驱的启动压力梯度存在很大的关系,基于微流量计量仪,通过"压差-流量"法,精确测定了油藏聚驱的启动压力梯度,深入分析了油藏非线性渗流特征。
The recovery rate of polymer flooding has a great relationship with the starting pressure gradient of reservoir flooding.Based on the micro-flowmeter,the "pressure difference-flow" method is used to accurately determine the start of reservoir flooding.The pressure gradient is used to analyze the nonlinear seepage characteristics of the reservoir.
