本文以岩心、测井及测试资料为基础,研究了南泥湾油田长6储层的非均质特征,研究表明:本区长6储层单砂体内部渗透率的变化复杂,主要受沉积环境和成岩作用的影响,层间非均质性较强,平面砂体呈带状展布,在横向上连通性差。岩心薄片观察发现储层的微观孔隙分布也具有很强的非均质性。
Based on the core, well logging and testing data, the paper studies the heterogeneity of Chang 6 reservoir in Nanniwan Oilfield. The results show that the variation of permeability within the Chang 6 reservoir is complex and mainly affected by the deposition Environment and diagenesis. The interlayer heterogeneity is strong, the flat sand body is banded and the lateral connectivity is poor. The observation of core sheet shows that the micro-pore distribution of the reservoir is also highly heterogeneous.
