| 摘 要： | 在测定不规则样品以及小样品(如岩屑)的毛管压力时,水银封闭间隙现象对测量精度有着重要的影响。在研究水银封闭间隙现象的基础上,提出了用三次样条插值函数计算水银封闭间隙的新方法。应用此法很方便地取得了川东北部罗家寨气田飞仙关组鲕滩储层各类碳酸盐岩的水银封闭间隙数值范围,分析了其对毛管压力曲线的影响,并依此对毛管压力进行了修正,以提高毛管压力资料质量,方便了应用。

| Abstract: | When measuring the capillary pressure of any irregular or small core samples, the accuracy is depended on the mercury blind pore volume. On the base of studying the mercury blind pore volume phenomenon, a new method by using the cubic splines interpolating function to calculate the mercury blind porevolume comes on. Thus, it is easy to get the right value of mercury blind pore volume of olitic carbonate rocks in Feixianguan Formation, Luojiazhai gas field, in northeastern, Sichuan, China. Based on analyzing the influence of the mercury blind pore volume, the capillary pressure curves are corrected, so the quality is improved and the application of the capillary pressure curves is expended. |
