With the ability for the hydrocarbon mixture in rock being separated into single component, the identification of reservoir oil property, the interference that decontaminates,
Oil-gas-water layer evaluation etc. played an important role, and effective technological means is provided for In Oil Field Exploration And Development.But due to
Oil reservoir, the thermal evaporation constitutional diagram form of oil-water common-layer are similar, therefore the bad differentiation of oil reservoir, oil-water common-layer, referring to Fig. 1.
Invention content
The purpose of the invention is to provide it is a kind of more it is reasonable effectively utilize the unidentified compound of hot-vibration sifter component
The method of form and content identification of hydrocarbon water layer, fundamentally solving existing thermal evaporation gas chromatographic technique can not be from composition chromatograph chart
In the problem of accurately distinguishing oil reservoir and oil-water common-layer, good classification effect.
The technical scheme is that：
A method of using the unidentified compound form of hot-vibration sifter component and content identification of hydrocarbon water layer, feature exists
In including the following steps：
1), hot-vibration sifter constitutional diagram is detached according to n-alkane and unidentified compound；
2), the spectrogram at the unidentified compound component peak that observation is separated, studies unidentified compound component peak shape state,
Using the subtle variation of oil in spectrogram, identifies different fluid property layer, that is, distinguish oil-gas-water layer；
3) total peak area for, calculating separately n-alkane and unidentified compound component peak is identifying peak area, is not knowing
Other peak area, total peak area have identified that peak than total peak area and has identified peak than unidentified peak face than total peak area, unidentified peak
Two parameters are selected to draw hot-vibration sifter interpretation chart as horizontal, ordinate in six parameters of product.
The above-mentioned method using the unidentified compound form of hot-vibration sifter component and content identification of hydrocarbon water layer, step 1)
In, using chromatographic work station separating normal alkane and unidentified compound, qualitative and quantitative analysis is carried out to component, wherein qualitative
It is to determine that the title of the compound in component, the content of quantification of each compound of determination calculate all compounds first
Then peak area again calculates identified all n-alkane peak areas, the two is subtracted each other as corresponding unidentified
The peak area of compound, and then obtain the spectrogram of unidentified compound component.
The above-mentioned method using the unidentified compound form of hot-vibration sifter component and content identification of hydrocarbon water layer, step 2)
In, the variation that oil is subtle in spectrogram is identified using fingerprinting methodology.
The beneficial effects of the invention are as follows：
This method can efficiently solve that constitutional diagram is similar, the problem of being not easy to judge properties of fluid in bearing stratum, by heat
Evaporated components figure carries out the separation of n-alkane and unidentified compound, then observes the subtle change at unidentified compound component peak
Change, and calculate the total peak area of n-alkane and unidentified compound peaks, and then draw interpretation chart, classify, obtains
Good classifying quality.
