With the continuous development of petroleum exploration technology, quantitative fluorescence technology as an important part of logging. In order to better reflect the set
The function of the instrument can be brought into full play to improve the compatibility of the software, the comprehensiveness and safety of the data. I
The company has developed the ofa-3dii three-dimensional oil fluorescence instrument which not only has all the functions of two-dimensional fluorescence instrument, but also can meet the field needs
Analyzer.
YST-3DIII three-dimensional petroleum fluorescence analyzer system is a revolutionary change of three-dimensional quantitative fluorescence analyzer
It has the advantages of high sensitivity of signal acquisition, USB signal transmission, fast image processing, one sample
The collection and analysis time is shortened to one minute, and the instrument is more suitable for field operation; YST-3DIII three dimensional quantitative fluorescence analyzer software
It has the characteristics of user-friendly interface and simple operation.
Advanges
1. The selectivity of excitation wavelength
Different oils and additives have different optimal excitation wavelengths and emission and reception wavelengths. The excitation and emission wavelengths used in three-dimensional fluorescence analysis technology are 200-800nm, which can fully excite the maximum fluorescence intensity int of fluorescent substances, including the optimal excitation wavelengths of different oils and additives, so as to ensure that the light oil is not easy to leak, It can also fully distinguish the fluorescent interference of additives.
2. The sensitivity of fluorescence analysis is increased by 10-35 times
The sensitivity of fluorescence analysis is increased by 10-35 times. N-hexane is used as extractant to overcome the quenching effect of carbon tetrachloride or chloroform on crude oil in traditional fluorescence logging（ Note: the analytical reagent used in this system is n-hexane, and its extraction sensitivity is higher than that of other reagents. Users can also use different analytical reagents according to their own actual situation.)
3. Visual interpretation of atlas
Stereogram and fingerprint directly and comprehensively reflect the fluorescence characteristics of various oil and mud additives. The formed three-dimensional image distinguishes the fluorescence intensity of samples at different wavelengths with different colors, and the fingerprint directly distinguishes different oil and mud additives.
4. Complete distinction between oil quality and mud additives
The excitation wavelength range of three-dimensional fluorescence analysis technology is 200-800nm. Different oils and additives have different optimal excitation wavelength and emission and reception wavelength. Different fluorescent substances can be directly distinguished from the spectrum. At the same time, the difference spectrum function is used to deduct the interference of mud additives to the reservoir, which completely solves the problems of organic matter fluorescence interference and oil mixing in drilling fluid additives.
5. The equipment is durable and not easy to damage
High speed motor, integrated optical components, high sensitivity of signal acquisition, USB signal transmission, fast image processing, a sample acquisition and analysis time is only one minute. The cuvette of the sample pool is sealed and covered, which is convenient for sample preservation and reduces the pollution to human and environment. The instrument has strong anti-interference ability, withstand voltage, temperature, humidity and earthquake resistance. Compared with the same kind of imported instruments, it has less influence factors and more stable performance, which is suitable for oil field exploration.
