针对塔里木盆地高温高压高含蜡凝析气的析蜡规律进行了研究,结果表明,高含蜡凝析气的相态特征极为复杂,在不同温度、压力条件下,有气相、液相单相,气-液、气-固两相,以及气-液-固三相等许多相态变化。压力对高含蜡凝析气的蜡析出温度有明显影响。压力很高时,对蜡析出温度影响不大;压力接近露点压力时,蜡析出温度随压力下降而升高;压力低于露点压力后,析蜡温度随压力下降而降低。
Aiming at the wax precipitation regularity of high temperature and high pressure waxy condensate gas in Tarim Basin, the results show that the phase behavior of high waxy condensate gas is very complicated. Under different temperature and pressure conditions, the gas phase and liquid phase single phase , Gas-liquid, gas-solid two phases, and many phase changes such as gas-liquid-solid three phases. Pressure has a significant effect on wax precipitation temperature of highly waxy condensate. When the pressure is high, the wax precipitation temperature has little effect; when the pressure is close to the dew point pressure, the wax precipitation temperature increases with the pressure drop; the pressure drops below the dew point pressure, the wax temperature decreases with the pressure drop.
