商河油田岩石物理相平面展布特征研究

Petrophysical Facies Plane Distributional Properties in Shanghe Oilfield

利用计算出的商河油田储层的流动带指标,对商河油田沙二下砂岩储层岩石物理相平面展布特征进行了预测,并对其岩石物理相分布图和沉积微相图进行了比较。利用划分的4大类岩石物理相成果,探讨了岩石物理相与剩余油分布的关系,指出Ⅱ、Ⅲ类岩石物理相是该油田目前剩余油分布的主要区域。

Petrophysical facies distributional properties in Es2 reservoir ot Shanghe Oilfield is predicted by using the indications calculated for reservoir flowing belt in the oilfield, the diagram of the petrophysical facies distribution is contrasted with that of sedimentary microfacies. The relationships between the petrophysical facies and residual oil distribution are discussed by using identified 4 categories of results of petrophysical facies. It is pointed out that Category II, Category III of petrophysical facies are the key areas of residual oil distribution of the oilfield.
