摘要(Abstract)：

储层的非均质性是影响油气藏油、气、水渗流及油气采收率的主要内因。所以进行储层非均质性对水驱油效果的影响实验研究 ,找出其影响规律 ,对搞清油藏剩余油的分布、采取合理性措施、提高采收率显得十分必要。本文采用天然岩心串联组合方法 ,进行了平面非均质性对水驱油效果的影响实验研究。结果表明 ,驱替顺序及岩石非均质程度是影响平面非均质油藏采收率的主要因素 ,高渗区注水低渗区采油可获得更高的采收率。该结论可以直接指导油藏开发和剩余油挖潜。
Storing floor horizontal heterogeneity character is mostly inner cause affecting oil,gas and water seeping and oil and gas recovery ratio. In order to find out its affecting law, to find out reservoir remaining oil distributing , to adopt rationality measure and to improve oil reservoir recovery ratio, it is quite need that carrying through affecting experiment study opposing water driving oil impact of storing floor heterogeneity character. This paper puts up that affecting experiment opposing water driving oil impact of storing floor horizontal heterogeneity character by means of savageness rock core in series combination. The result indicates that driving order and degree of rock heterogeneity character is mostly factors of affecting horizontal heterogeneity character oil reservoir recovery ratio, and that it can be obtained the taller recovery ratio by pouring in high permeability region and picking in low. This conclusion can be used to guide directly oil reservoir development and tapping the latent of remaining oil.
