The invention discloses a three-dimensional quantitative fluorescent oiliness index calculation method. The method comprises the following steps of: 1) determining the wavelength ranges of light, medium and heavy components; 2) determining the strengths of light, medium and heavy components; 3) determining an oiliness index calculation method: by comparing the peak volume parameters of the light, medium and heavy components, a new calculation method of the oiliness index is preferably selected, and a new definition is given and defined as the oiliness index; and 4) establishing an oil quality index to judge the crude oil density and the crude oil viscosity: establishing a standard according to the analysis data and the oil test conclusion. The invention has strong applicability and metering attribute, can trace and transmit the magnitude, ensures the accuracy of analysis data, and provides reliable basis for the calculation of the three-dimensional quantitative fluorescence oiliness index.
Description
technical field [0001] The invention relates to the application field of instrument parameters, in particular to a method for calculating a three-dimensional quantitative fluorescent oiliness index. Background technique [0002] With the wide application of quantitative fluorescence logging technology in the field of petroleum exploration, this technology has played an important role in the discovery and identification of oil and gas shows, and has been recognized by customers. The quantitative fluorescence instrument has also been upgraded from a two-dimensional quantitative fluorescence instrument to a three-dimensional quantitative fluorescence instrument, but the three-dimensional quantitative fluorescence oiliness index still uses the calculation method of two-dimensional quantitative fluorescence, which cannot really play the technical role of three-dimensional quantitative fluorescence. Quantitative fluorescence oiliness index plays an important role in judging the pr...
