A、低收缩率原油液相体积分数较高,原油中含重烃数量较多,地面气油比较小,通常小于0m3/m3,原油相对密度较高,通常大于0.876
B、高收缩率原油产出的液体数量较低收缩率原油明显减少,原油中含轻烃分子数量相对较多,地面气油比相对较高,一般为90--1500m3/m3,地面原油相对密度一般小于0.78
C、凝析气藏又称反凝析气藏,温度介于临界温度和临界凝析温度之间,在地面分离器条件下有液态烃析出,称为凝析油,相对密度小到0.74,色浅且透明,凝析气藏气油比可达12600m3/m3
D、湿气气藏地层条件下流体始终呈气态,而在地面分离器条件下有一些液态烃析出,其相对密度小于0.78,地面气油比一般小于18000 m3/m3;干气气藏和士气气藏类似,在地面分离器条件下页有液态烃析出
