Problems solved by technology

[0005] Firstly, during the extraction process, organic matter will suffer structural damage due to the action of heat and liquid, and at the same time, impurities will be introduced to cause property changes; secondly, the sample is first extracted, cracked, and then observed with an electron microscope. Metastasis occurs, and in situ imaging cannot be achieved, so the accuracy of the experiment cannot be guaranteed

Abstract

The present application provides a method and device for cracking organic matter. The method includes: performing optical path calibration and intensity testing on a focused laser to obtain a focused laser beam with a specified light intensity; preprocessing an organic matter sample to obtain a scanning electron microscope sample; selecting an organic matter region on the scanning electron microscope sample; The focused laser beam cracks the organic matter region, and performs real-time imaging on the organic matter region. The method and device for cracking organic matter provided by the embodiments of the present application are based on scanning electron microscope and focused laser, and can observe the cracking process of organic matter in situ. This method is an in-situ analysis method that truly observes the changes in the structure and morphology of organic matter with time during the cracking process.

Description

technical field [0001] This application relates to the technical field of organic matter geochemical research, in particular to a method and device for cracking organic matter. Background technique [0002] Organic matter geochemistry is a branch of geochemistry, which mainly studies the composition, structure, origin and evolution of organic matter in geological bodies. The research content can include: the distribution and type of organic matter, the origin and evolution of organic matter. Since the 1960s, the viewpoint of petroleum origin that kerogen degrades into oil has been widely accepted, people have realized the importance of studying organic matter, correspondingly carried out a lot of research on source rock evaluation and oil source comparison, and successfully developed a large number of new Methods and new technologies, including microscopic identification of kerogen microscopic components, high-resolution electron microscope imaging, kerogen separation and p...
