摘要: 根据压汞、半渗透隔板等途径确定的毛细管压力曲线对核磁毛细管压力进行刻度,提出了通过T2分布获得地层毛细管压力信息的方法。选取了准噶尔盆地储集层50 多块岩样进行了核磁共振、半渗透隔板的实验研究,分析了核磁共振T2分布与孔径分布的相关性,对压汞和半渗透隔板毛细管压力曲线进行了对比分析,建立了核磁共振T2分布与毛细管压力曲线的转换关系,从而为准噶尔盆地复杂孔隙结构低电阻油气藏测井解释提供了新方法。

Abstract: This paper discusses the method for obtaining formation capillary pressure from MNR T2 spectrum by mercury penetration and semi-permeable plate experiment to determine the capillary pressure curve and further calibrate the MNR capillary pressure. Over 50 core samples from Jungar basin are tested with MNR and semi-permeable plate. Correlation between MNR T2 spectrum and aperture distribution is conducted. Comparison of capillary pressure curves from mercury penetration and semi-permeable plate is presented to establish the conversion between MNR T2 spectrum and capillary pressure curve. This provides a new method for log interpretation of complex pore structures and low resistivity hydrocarbon reservoir.

Key words: sandstone, MNR, semi-permeable plate, capillary pressure
