| 摘 要： | 油藏投入注水开发以后,其地层原来的润湿性将发生改变,亲油地层逐渐向亲水地层转变,油水相对渗透率也将发生一定变化。因此,通过对注水开发后油水相渗曲线变化特征以及渗透率级差与渗流速度关系的研究,总结出靖安油田五里湾一区长6油藏在注水开发水驱油过程中渗流变化规律,从而科学指导油藏开发调整。

| Abstract: | After the reservoir turning to flood development,the intrinsic wettability has changed.The oil-wetted layer gradually changed to water wetted layer.The oil/water relative permeability also have some changes.This paper researched on the change characteristic after the reservoir turning to flood development.And also research on the relation between permeability contras and Darcy velocity.This paper summarized the changing rule of water driving in the flood development in Wuliwan Chang 6 reservoir of Jing'an o... |
