摘　　要：长细管实验是确定混相驱最小混相组成MMC的经典方法,以长细管实验确定了阿尔及利亚某油田富气最小混相组成MMC。在温度83.9℃下,压力为97.12MPa时最小混相MMC在37.6∶62.4附近,压力为110.16MPa时最小混相组成MMC在37.1∶62.9附近。鉴于压力对混相组成MMC影响较大,建议在矿场实施时适当增加液化气比例。The minimum miscible composition(abbreviation MMC) of rich gas in Zarzaitine Oilfield is defined by the long-tube test.MMC is around 37.6 :62.4 under the pressure of 97.12 kg/cm2 and temperature of 83.9 ℃,and around 37.1 :62.9 under the pressure of 110.16 kg/cm2.In view of the great impact of pressure on MMC,it is proposed to increase the appropriate proportion of GPL in the course of the field conduct.
