The utility model relates to a separator especially relates to a horizontal sample catch water of steam quality of oil industry thermal recovery underground viscous crude steam-injection boiler for high pressure saturated steam quality detects.

Background

At present, most of oil field steam injection boilers used in China are saturated steam boilers, the feed water of the oil field steam injection boilers is hardness-removing softened water, so that the dryness of steam at the outlet of the boiler is required to be controlled to be below 80%, and 20% of water is reserved to dissolve the salt in the water, so that the safe operation of the boiler is ensured. The dryness of the steam determines the heat carried by the steam in unit mass, and for steam injection oil extraction, the higher the dryness of the steam is, the more the heat carried by the steam in unit mass is, and the better the oil extraction effect is. Therefore, the control of the steam dryness is very important to the safe operation of the boiler and the cost and the effect of oil extraction.
