Embodiment Construction

[0028] A method for microscopic identification of multimodal organic components, comprising the following steps:

[0029] S1. Collect the rock sample matrix pictures to the computer in different lighting modes;

[0030] In a preferred solution, the illumination mode in step S1 includes at least two or a combination of two or more of white light, red light, yellow light, blue light, green light and fluorescence.

[0031] In a preferred solution, the illumination mode in step S1 includes white light and fluorescence.

[0032] In a preferred solution, the fluorescence is violet laser, blue-violet laser or ultraviolet light.

[0033] In a preferred solution, the white light is a light source emitted by a high-pressure mercury lamp or a white laser light source combined with multi-color lasers;

[0034] The red, yellow, blue and green light sources all use laser light sources.

[0035] During the acquisition process, in order to ensure that image information is not missed during...

Abstract

The invention provides a multi-mode organic component microscopic identification method, comprising the following steps: S1, collecting rock sample matrix images to a computer in different illumination modes; S2, splicing the matrix images; S3, performing particle edge tracking on the images in different illumination modes , obtain the particle edge tracking map in different modes; S4, superimpose the particle edge tracking map in different modes, and retain the edge tracking path superposition; S5, classify and extract; S6, fill in different colors according to the classification; S7, count the number of color pixels, and find And; through the above steps to achieve rapid microscopic identification of the relative content of organic components. Through the above steps, rapid microscopic identification of the relative content of organic components is achieved. By adopting the scheme of automatic scanning, intelligent splicing and intelligent identification, high-precision and high-precision identification of the organic components of rock samples can be achieved.

Description

technical field [0001] The invention relates to the technical field of petroleum and natural gas geological exploration, in particular to a multi-mode organic component microscopic identification method. Background technique [0002] Organic microcomponents are hydrocarbon-forming substances in source rocks. Differences in their content and composition have important effects on the properties and hydrocarbon-generating characteristics of coal and source rocks. The quantification of organic micro-components in the early stage was based on the coal petrology method, and the single-view field analysis visual estimation method was used for estimation. Among them, the most widely used is the International Committee on Coal and Organic Petrology (ICCP) in 1971, which gave the method of estimating the content of each organic micro-component by the point method. Based on the identification of micro-components, this method determines the percentage of various components in the volu...
