In the process ofoil production, the penetrationofoil-content rock is determined by rock framework's effective stress.
在采油过程中,含油岩石的渗透率取决于岩石骨架的有效应力。

Based on numeral simulation result of combination flooding composing, oil displacement experiments are carried out in different penetration ratio natural core and artificial core.
并在数模优化组合驱段塞构成的基础上,对不同渗透率的天然岩心与人造岩心进行了驱油实验。

During drilling horizontal well, usually adopt geometry steerable drilling technology to increase the penetration rate of borehole track in oil reservoir.
