1原油计量
Q油 =96V15（1-BS&W）（1-Shr）KK表
=48V30（1-BS&W）（1-Shr）KK表
=24V60（1-BS&W）（1-Shr）KK表
式中：Q油—原油产量，m3/d
V15—每15分钟流量计读数增值，m3
V30—每30分钟流量计读数增值，m3
V60—每60分钟流量计读数增值，m3
BS&W—原油含砂含水，%
Shr—原油收缩率，查表或用测定仪测量，小数
K—原油体积系数，查表，与密度、温度有关
K表—流量计校验系数，计量罐读数与流量计读数之比。

式中：Q气英制—天然气产量，千立方英尺/日（MSCFD，kft3/d）
Q气国际—天然气产量，m3/d
Fb—孔板系数，查表
Y2—膨胀系数，查表。上游取静压时查Y1
Fg—比重系数，Fg=（1/g）1/2
g—天然气比重，空气=1.000
Ftf—温度系数，Ftf=[520/（Tf+460）]1/2
Tf——华氏温度，℉
Fpv—超压缩系数，查表
Hw—压差，英寸水柱（″H2O）
Pf—下游静压（绝对），psia，读数﹢14.7(≈15)
