应用压力恢复曲线对不同类型储层的低地饱压差油气藏求取饱和压力，不仅弥补了ＰＶＴ分析数量有限和取样条件苛刻等缺陷，而且拓宽了压力恢复曲线的应用范围，该方法应用于准噶尔盆地东部油区的火烧山、北三台油田，取得了令人满意的结果。
Applying the pressure recovery curve to obtain the saturated pressure of low-lying saturated gas reservoirs of different types of reservoirs not only makes up for the limited number of PVT analysis and harsh sampling conditions, but also widens the application range of pressure recovery curve. This method is applied to Junggar The Huoshaoshan and Beisantai oilfields in the eastern oil basin of the basin have achieved satisfactory results.
