摘要: 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。

Abstract: The study of wax precipitation in gas condensate with high temperature, high pressure and high wax from Tarim basin indicates that the phase behavior of such a gas condensate is extremely complex under different temperatures and pressures, showing gas, liquid, gas-liquid, gas-solid and gas-liquid-solid phases. The pressure has a distinct influence on the temperature of the wax precipitation: when the pressure is high, the influence is not clear; when it is close to dew point pressure, the temperature goes up with the drawdown of pressure; when it is lower than dew point pressure, it goes down with the decrease of pressure.

Key words: gas condensate, phase state, wax precipitation, temperature
