安塞xx井区储层非均质性及其对剩余油分布的影响

Reservoir heterogeneity and its influence on remaining oil distribution in well XX area,Ansai

主要以长8段为例,在经过水驱之后,储层渗透率非均质性的强弱对剩余油分布状况有直接影响,强非均质性区是剩余油分布的有利部位。

This paper will take Chang 8 member as an example,after water flooding,the strength of reservoir permeability heterogeneity has a direct impact on the distribution of residual oil,strong heterogeneity area is the favorable part of residual oil distribution.
