Abstract: The sedimentary environment of H oil fields in Daqing is complicated, and the data of well logs are limited, so it is hard to use faciescontrolled modeling to predict the heterogeneity of the layers between wells. Using the data of the digital phase for micro layer and the geological research results as the constraint conditions，analyzing statistical regression of multiple phase permeability variation curves of the channels, the permeability ratio relations between edge and middle of the channel are definited. The results show that: in contact with a different deposition, the permeability in channel edge is about 0.2～04 times as high as the center channel. The results can be used as a constraint condition in faciescontrolled modeling process. The properties of the spatial distribution of reservoir parameter heterogeneity characterization accuracy and conformity can also be improved.

摘要： 大庆H 油田沉积环境复杂,由于测井数据有限,采用相控随机建模不能较好地体现不同岩相单元之 间储层性质的非均质特征。通过对数字化后的沉积微相平面分布数据进行研究,以地质研究成果作为约束条件,统计回归出多期河道渗透率变化规律曲线,确定河道边部渗透率与河道中部渗透率的倍数关系。结果表明,与不同的沉积相接触时,河道边部的渗透率为河道中部渗透率的0.2~0.4倍,以此作为相控建模的约束条件,可以提高模型储层空间分布和物性参数非均质性刻画的精度和符合度。
