| 摘 要： | 本文以辽河油田新开地区沙一、沙三段砂岩储层为例阐述了如何利用原始压汞数据建立注汞压力与进汞饱和度之间的函数关系，然后再从这些关系式出发导出它们的一些地质应用。研究结果表明:新开地区注汞压力与进汞饱和度之间存在着良好的双曲线函数关系，根据这些关系可以利用孔渗两个参数反求毛管压力和毛管压力曲线，很方便地计算某一样品的渗透率以及任意进汞区间的渗透率贡献值。

| Abstract: | This paper took the sandstone reservoirs of Liaohe Oilfield (Es1,Es3 ) as a case and elaborated how to establish functions between mercury injection pressure (Pc) and mercury saturation (SHg), then to conduct some geological applications of these functions. The results indicated that there exists a good hyperbola relationship between Pc and SHg in the studied area. From these functions one can calculate the capillary pressue .obtain the capillary pressure curves from porosity and permeability, and compute the permeability and permeability contribution at any SHg intervals. |
