摘要

饱和度计算是评价油气层的主要参数之一,文中以塔河南油田三叠系低电阻油藏部分油井为例,比较了阿尔奇方程和Waxman2Smit s 模型饱和度评价的结果,并以核磁共振实验结果计算的束缚水饱和度为基准,认为用Waxman2Smit s 模型评价这一地区的含水饱和度更为合理。

Abstract

Water saturation is one of t he key parameters to evaluate hydrocarbon reservoir . Based on t he core analysis result s and the bound water saturation derived rom the nuclear magnetic resonance (NMR) test results for several wells of Triassic low resistivity reservoir in southern Tahe Oilfield , the comparison of the evaluation results of water saturation derived from Archie equation and Waxman-Smits model respectively is carried out . The result shows that using Waxman-Smits model to evaluate water saturation in this area is more advisable.
