That is different from the elevation above sea level atmospheric pressure and water temperature at 20 degrees centigrade higher than the saturation vapor pressure.
即不同海拔高程处的大气压力和高于20摄氏度水温时的饱和蒸汽压力。
2
Mixing of injected gas and reservoir oil will change the initial saturationpressure, affect the deliverability of the oil.
注入气与地下原油混合将改变原油藏流体的饱和压力，影响原油流动能力。
3
It is defined by PVT sampling analysis with high cost and related experience formulae with low accuracy at present, so it is difficult to define the saturationpressure.
