       毛细管压力曲线在油藏表征中具有重要意义。由于储层的非均质性,单一的毛细管压力曲线不适用于整个储层深度。


       近日,伊朗阿米尔卡比尔理工大学Yousef Rafiei 博士和 Mohadeseh Motie 博士研究了不同水力流动单元(HFU)分类技术在储层极端非均质性方面的应用,以提高伊朗碳酸盐岩油藏中毛细管压力的归一化程度。主要利用测井、岩心分析实验室数据,采用不同的技术,在伊朗南部的一个碳酸盐岩油藏中识别流动单元。这些技术包括伽马测井和密度测井方法,参数涉及流动层指数,毛细管压力和Winland参数。然后利用Desouky方法使用压汞数据对每个识别的流动单元毛细管压力曲线进行归一化处理。研究表明,HFU分类能够显着改善毛细管压力曲线的归一化程度。

Abstract:

    Capillary pressure curves is of great importance in reservoir characterization. Due to the reservoir heterogeneity, no single capillary pressure curve can be used for the entire reservoir depth. This paper aims to examine the application of different techniques of hydraulic flow unit (HFU) classifications in overcoming the extreme heterogeneity of the reservoir in order to improve normalization of capillary pressure in one of the Iranian carbonate oil reservoirs. In this study, well log, routine and specific core analysis lab data have been used to identify flow units by employing different techniques in a heavy oil carbonate reservoir in the south of Iran. These techniques include gamma ray and density log method, flow zone indicator, capillary pressure curves and Winland parameter. Then, mercury injection data has been used by employing Desouky's method to normalize capillary pressure curves for each identified flow unit. According to this study HFU classification significantly improved normalizing of capillary pressure curves.

Keywords: Heterogeneity, hydraulic flow unit, capillary pressure.
