本文叙述了对含不稳定矿物如粘土或石膏的岩心,在测定孔隙度和油水饱和度时,温度和湿度的影响情况。室内实验发现老君庙、中原和冷湖油田的一些岩心油水饱和度超过100％。最后讨论了如何选择分析方法。
This article describes the effects of temperature and humidity on the determination of porosity and oil-water saturation for cores containing unstable minerals such as clay or gypsum. Laboratory experiments found that some core oil-water saturations in Laojunmiao, Zhongyuan and Lenghu Oilfields exceeded 100%. Finally, we discuss how to choose the analytical method.
