Description
Technical field
The utility model is relevant for a kind of mass dryness fraction ST, be particularly to a kind of in the oil recovery observation process, a kind of minor diameter mass dryness fraction ST that the thick oil filling vapour quality in the notes vapour well of various complex hole condition is monitored.
Background technology
Along with the development of oil-field thick-oil development technique, the heat extraction by steam injection technology has become main means of thickened oil recovery, and the quality of notes vapour quality directly has influence on the exploitation of viscous crude, therefore injecting-steam viscous crude oil well is annotated the vapour quality and monitors more and more urgent.
In the prior art; The main mass dryness fraction ST that adopts carries out quality monitoring to annotating the vapours of injecting in the vapour well; This mass dryness fraction ST has a sampling storage barrel, when this mass dryness fraction ST is lowered to annotate in the vapour well after, the vapours of annotating in the vapour well flows in the sampling storage barrel from the air intake opening of mass dryness fraction ST; Close the mass dryness fraction ST this moment; The vapours sample of annotating a certain position, vapour down-hole just is retained in the mass dryness fraction ST, on degree of promotion ST, the vapours sample taken out and detect from the mass dryness fraction ST get final product.
