摘要
主要介绍了超低渗岩心油水饱和装置的结构原理以及岩心饱和罐的设计计算方法,分析了饱和罐正负压切换密封的实现方式、结构特点以及性能优点。通过试验和应用,该装置明显提高了低渗、超低渗岩心的饱和度。
Both the structure principle of the ultra-low permeability core oil-water saturation device and the design method of the saturation tank are introduced. Also, the technique, structure characteristics and performance advantages of the saturation tank pressure switching seal are analysised. Through experiment and application that the device can significantly improves the accuracy of low,ultra-low permeability core saturation.
