A kind of built-in integrated form jet cyclone separator
The utility model relates to a kind of heterogeneous fluid separator; Especially a kind of built-in integrated form jet cyclone separator.
At the crude oil transmission metering system; Particularly in the well head one-well metering system; The common oil gas separating system is opened gas phase and liquid phase separation that oil mining goes out, measures liquid phase quantity, gas phase quantity, the liquid phase moisture content in the crude oil respectively and then extrapolates oil production, realizes producing the purpose of metering; Support Oilfield Information management and decision-making, foundation and guarantee are provided for measuring, control, improve oil production.
Cyclone separator compares traditional horizontal separator, vertical separator because volume is little, separating rate is high, good separating effect is come out by mass development, is that Chinese invention patent " helical pipe composite gas and liquid separator ", the patent No. of 200610009659.9 (publication number is CN1820816A) is that Chinese utility model patent " a kind of spiral-flow type gas-liquid separator ", the number of patent application of ZL200720108504.0 (publication number is CN201055811Y) is the Chinese invention patent " a kind of double-barrel spiral-flow type gas-oil-water separator " of 200910153153.0 (publication number is 10664720) like number of patent application.
Though aforementioned cyclone separator technology has very much progress, still have big gap with practical application request, the ubiquity space availability ratio is low; Weight and volume is bigger, as the separate measurement device, when demarcating the lower accuracy metering device; Aspect transportation, show certain limitation, especially on-the-spot in the oil field of crude oil transmission, mobile transportation is inconvenience very; Even can only make fixedly, can't be used for demarcating the metering device of lower accuracy; When being used for the offshore oil production metering and separating with gas production, platform by volume is restricted to some extent, too big to the expense number increase of production platform, it is bigger to promote difficulty.In order to satisfy the crude oil transmission demand, be badly in need of the gs-oil separator that exploitation is in light weight, volume is little, conveniently moving is stable, adapt to the demand of crude oil transmission metering as early as possible.
