| 摘 要： | 洪湖油田为中低孔隙度低渗透率油藏,根据油田特征,经过室内实验研究了单相、两相渗流规律,确定流体在多孔介质中的流动特征,并分析了水驱油实验成果,确定了最佳驱油效率.单相油渗流实验证明了洪湖油田低渗透岩心存在启动压力梯度;两相实验测试了油水两相相对渗透率曲线,对油藏开发后期的含水规律进行了预测.

| Abstract: | Honghu reservoir features lower-middle porosity and low permeability.By virtue of laboratory investigation of single-phase and double-phase percolation laws,flow performance of fluid in porous media has been found. A best displacement efficiency has also been confirmed on the basis on the analysis of flood-pot test.Single-phase seepage test demonstrates that there exits kick-off pressure gradient in Honghu reservoir with low permeability core;the experiment of double-phase flow has tested oil-water double-phase relative permeability curve,and has predicted water cut performance in later reservoir development. |
