| 摘 要： | 高饱和压力油藏的主要特点是油气比非常高,原油体积系数非常大,地饱压差比较小.该类油藏在一次采油的开发过程中,存在当地层压力低于饱和压力时,油层脱气严重,地层压力大幅下降,导致采出程度低.特别是地饱压差比较小,所以膨胀时间较短.很快进入大幅度收缩,当压力从230kgf/cm2下降到20kgf/cm2时,体积系数收缩卒达到... |

| Abstract: | High saturation pressure oil reservoirs are of high gas - oil ratios,greater oil formation volume factors and smaller differences between reservoir pressure and saturation pressure.In the process of the primary recovery,if the formation pressure is lower than the saturation pressure,serious degasification will occur in the reservoir,and formation pressure will decrease sharply,which will result in a low recovery degree.In particular, if the difference between reservoir pressure and saturation pressure is re... |
