Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil and gas exploration, and particularly relates to an organic micro-component positioning device and method in a light sheet and an optical microscope, which is suitable for positioning of organic micro-components under observation of an optical microscope. BACKGROUND

[0002] The organic micro-component refers to an identifiable organic component under a microscope, which is mainly derived from residues of paleontological tissues and organs and their thermal evolution products; and can be divided into seven micro-groups according to genesis and properties. The conventional optical microscope can realize identification and image acquisition of the organic micro-component, but cannot realize accurate positioning of the organic micro-component. The argon ion polishing-field emission scanning electron microscope is a common means for characterization of micro-pore structures of shale reservoirs, but cannot directly identify the organic matter type by relying on scanning electron microscope observation alone. Therefore, the combination of the optical microscope and scanning electron microscope and Raman spectrum can realize multi-scale and multi-aspect researches on the organic matter morphology, color, hardness, pore development characteristics and composition.

[0003] Further, the heterogeneity of the organic matter pore has a certain influence on the evaluation of the shale reservoir, and the heterogeneity is controlled by the organic micro-component to a certain extent. Therefore, the research on the pore development characteristics of the specific micro-component is particularly important. At present, the optical microscope observation is the main means for identification of the micro-component, and the Raman spectrum can identify different micro-components from the micro-area. The scanning electron microscope can directly and intuitively obtain the pore development of the organic matter, but cannot accurately identify the organic matter type. Therefore, the micro-component group needs to be determined under the low-magnification optical microscope, the component is identified and the position of the specific component is marked, and then the scanning electron microscope is used to quickly locate the marked micro-component and observe the micro-nano pore details.

[0004] In the prior art, the scanning electron microscope and the optical microscope are combined for the research on the heterogeneity of the organic matter pore. The scanning electron microscope is used to observe the organic matter pore, a characteristic point is selected as a starting point, the organic matter characteristics are recorded along the anti-S-shaped path of the bedding, and then the corresponding organic matter is found out by using the optical microscope according to the position marked during the scanning electron microscope observation, and the component identification is performed. The positioning method is time-consuming and inefficient by manual identification.

[0005] In the prior art, a micro-positioning scale sticker is designed, which can quickly locate the cells through the coordinate system on the sticker, but the sticker is suitable for transparent culture dishes and is not suitable for the light sheet sample for analysis of the organic micro-component. It can be seen that it is difficult to realize the quick and accurate positioning of the organic micro-component in the light sheet sample under the optical microscope. SUMMARY
