吴起油田Z油区延9_2砂岩沉积微相研究

Research on Sedimentary Microfacies of Yan 9_2 Reservoir in Z Oil Area of Wuqi Oilfield

Z油区近年来在延9_2油层试油取得较好效果,为明确延9_2油层沉积相特征,本文通过有限的岩心资料利用测井资料进行单井及联井的测井相分析,建立沉积微相的平面分布图,精细刻画延9_2层沉积微相在垂向及平面的展布特征,为该油区下一步的精细勘探开发部署提供有力依据。

In recent years, good results have been achieved in the oil test of the Y-9 2 layer in Z oil region. In order to clearly define the sedimentary facies characteristics of the oil layer, the logging data of single well and connected wells were analyzed through the limited core data, and the plane distribution map of the sedimentary microfacies was established, and the characteristics of the vertical and horizontal distribution of the Y-9 2 layer sedimentary microfacies were elaborated, which could provide a strong basis for the next fine exploration and development of the oil area.
