本文介绍了一种用国产材料研制的GBY-1型双岩芯室高压半渗透隔板仪。从国内工厂所研制的13种隔板中挑选出气驱水突破压力为7bar的冲压烧结陶瓷隔板,它适用于10md以上的油气储集岩岩样,所测得的毛细管压力—水饱和度关系曲线更为逼近油层条件,且具有不污染样品,测试精度高,重复性好等优点。目前已由江苏海安石油科研仪器厂批量生产。 This paper introduces a GBY-1 dual chamber high pressure semi-permeable separator developed by domestic materials. Out of the 13 kinds of separators developed by domestic factories, a punched and sintered ceramic separator with a breakthrough pressure of 7 bar is selected, which is suitable for the reservoir rock samples above 10md. The measured capillary pressure-water saturation relationship The curve is more close to the reservoir conditions, and has the advantages of non-contaminating samples, high testing accuracy and good repeatability. At present, Jiangsu MSC Oil Scientific Instrument Factory mass production.
