| Abstract: | This paper analyses the oil,gas and water saturation of two wells of core drilling with keeping formation pressure in Daqing Placanticline and draws a degassed correction chart of oil and water saturation.A comparative result shows that the oil and water saturation increases from the conventional value 88% to>96%.The relative coefficient of the degassed correction chart is >0.97,the realative deviation is <5%,and the accuracy of the chart is 95%. |
