摘要(Abstract)：

利用压汞资料对储层微观非均质性进行了研究 ,对比汞饱和度为 35 %的孔喉半径R35 值的分布与孔喉峰值分布 ,认为在同一地区 ,R35 值分布特征表征了储层孔喉分布特征 ,因此 ,R35 值分布的非均质特征表征了储层微观非均质性。对于非构造圈闭控制油藏 ,不同R35 值分布区间的储层 ,其储集的流体性质不同 ,这与流体在非均质储层内的二次运移和聚集有关。
This paper studies the micro heterogeneity of reservoirs using mercury injection data It compares the distribution of pore throat diameter R 35 value and pore throat peak value under the mercury saturation of 35% and proposes that the R 35 value distribution in an area characterizes the pore throat distribution So the heterogeneous distribution of R 35 value characterizes the micro heterogeneity of reservoirs In the reservoirs controlled by non structural trap, the reservoirs in different distribution intervals of R 35 value have different fluids, which is related to the second migration and accumulation of fluid in heterogeneous reservoirs
