辽河油田龙10 块主要储层S31段沉积微相主要为陆上辫状水道砂体、水下分流河道及三
角洲前缘薄层砂砂体，储层物性非均质性较强。利用水动力单元划分法（FZI）对该油田进行流动元的识
别和划分，根据FZI 值，划分成4 类流动单元，同时，充分应用密井网条件下的“硬数据”和地质家的经
验，采用确定性建模方法建立沉积微相模型，在沉积微相控制下，应用序贯高斯随机模拟方法建立储层
流动单元参数分布模型。实践表明，该方法能够很好地表征砂体的非均质性。

The micro-facies of 31 layer, the major reservoir in segment
Long 10 of Shhejie Formation in Liaohe Oilfield, includes braided
channel sand body on land, subaqueous distributary channel and
delta front sheet sand. The reservoir is serious heterogeneities. The
oilfield is identified and is divided into 4 kinds of flow units
according to the value of FZI in hydrodynamic unit way. The
modeling is built in a deterministic way with "hard data冶of closely
spaced wells and geologist’s experience. Based on the micro-facies
modeling controlled, the flow unit’s distribution is predicted by
Sequential Gaussian Simulation. The accuracy and practicability of
the method is verified by experiment.
