补充资料:凝析油
地层中处于高压高温条件下呈超临界状态的气藏,开采到地面时,由于压力和温度都降低,发生反相冷凝(retrograde condensation)所凝析出的液体产物称凝析油,未冷凝的气体称为凝析气井气。有时油田伴生气和湿性天然气(见天然气),由于温度降低而得到的冷凝液,也称为凝析油(见天然气化工),或称天然汽油。开采每立方米凝析气井气时,得到的凝析油量可多达数百克;油田伴生气和天然气中可得凝析油量较少,一般每立方米气只有几十克。
不同凝析气田所得凝析油性质有所不同,但组分均较轻,大部分为300℃以前馏分,一般呈淡黄色,相对密度在0.75~0.80间。从油田伴生气和湿性天然气中所得凝析油,根据来源及回收条件(温度及压力)不同,其组成也有所不同,主要是C4~C10烃类,为200℃以前馏分。
凝析油是管式炉裂解制取乙烯的良好原料,也可经蒸汽转化制取合成气或氢气。凝析油经加工亦可制得轻质液体燃料。
