划分岩石物理相的新方法及其应用

提出了应用模糊聚类划分储集层岩石物理相的方法。以大港枣南油田为例,选取反映储集层成因的沉积和成岩作用参数,应用该方法将研究区储集层划分为五类岩石物理相,并进一步分析了岩石物理相与油田生产指标之间的关系。研究表明,随着储集层岩石物理相级别的升高,储集层成因参数及统计物性特征逐渐变好,储集层产液能力也明显增强。本研究有助于寻找有利油气富集部位、剩余油气富集区,对油田调整挖潜具有一定的指导意义。

A Novel Method for Division of Petrophysical Facies with Application

A method for division of reservoir petrophysical facies by fuzzy clustering is proposed,Taking Dagang Zaonan oilfield as anexample and selecting the parameters of sedimentation and diagenesis ,the five types of petrophysical facies featuring the reservoir rocks in this studied area are given by this metho.And the relationship between the petrophysical facies and the production indices of the oilfield is analyzed.The study shows that with upgrade of the petrophysical facies level,both of the reservoir genetic parameters and the stratistical petrophysical properties gradually change better,so does related reservoir productivity.The conclusion does help to searching for the favorable oil/gas-enriched horizons and remained oil-gas abundant areas,Also,this is as a guide for further regulation and additional potentials in this oilfield.
