(B, ) the utility model relates to an oilfield produced liquid measures calibration device technical field, is a high temperature saturation fluid measurement calibration device, and it includes gas liquid separator, air cooling formula heat exchanger and measurement knockout drum, has the liquid of coming inlet on gas liquid separator, be fixed with between the upper portion of gas liquid separator's upper portion and air cooling formula heat exchanger with gas liquid separator and the communicating gas pipe of air cooling formula heat exchanger. The utility model has the advantages of reasonable and compact structure, convenient to use, the metering error who has avoided high temperature flash distillation and heterogeneous stream to arouse not only can improve the measuring accuracy to SAGD oil well extraction liquid, for the measuring equipment of individual well provides the error correction parameter, can learn the volume of the taking steam gentleness liquor ratio index of SAGD oil well extraction liquid moreover to can master the phase of SAGD oil well extraction liquid and constitute and change rule, provide technical support for follow -up process flow's optimization.
