| 摘 要： | 储层层间物性差异是影响非均质油藏水驱采收率的重要因素。层系内合理层间渗透率级差是提高储量水驱动用程度的关键参数。针对胡状集油田进行多层不同渗透率级差的长岩心水驱油试验,研究渗透率级差组合对采收率的影响,发现胡状集油田层系内渗透率级差小于6倍能显著提高水驱采率。据此在胡状集油田6个开发单元按渗透率级差重组细分开发层系,取得了较好的效果。

| Abstract: | The reservoir property difference between layers is an important factor seriously affecting the water flooding and recovery in heterogeneous reservoirs.A reasonable max/min permeability ratio between layers is the key parameter to improve the level of water flooding.Through the water/oil displacement experiment in long cores, which is made of 18 combinations of different permeability ratios.The conclusion is drawn that the different permeability ratios influence the recovery factor and the technology policy... |
