Abstract

The invention belongs to the technical field of organic matter pore identification, and discloses a quantitative characterization method and application for quickly determining organic matter pores based on a scanning electron microscope. The scanning electron microscope is used to determine the distribution position of the organic matter; the energy spectrometer and the form of the organic matter are used to determine the microscopic component type; Determine the organic pores by using the microscopic components of organic matter; determine the distribution position of organic matter, determine the type of microcomponents, and determine the development of organic pores. The present invention adopts scanning electron microscope to identify organic matter microscopic components, which can effectively solve the problem of small observation field when using scanning electron microscope to observe organic matter pores, it is difficult to find organic pores, and the observation time is long, which reduces the efficiency of experiments and scientific research. The scanning electron microscope of the present invention has high magnification, strong three-dimensional image, and simple sample preparation method; the relationship between organic matter pores and microcomponents can be directly observed, the enrichment mode, morphological characteristics and Contact relationship with minerals, identification of organic matter pores.

Description

Technical field

[0001] The invention belongs to the technical field of organic matter pore identification, and particularly relates to a quantitative characterization method and application for quickly determining organic matter pores based on scanning electron microscopy.Background technique

[0002] At present, the closest existing technology: At this stage, the exploration and development of shale gas is of great significance to changing the resource structure of my country and improving energy shortages. A large number of micro-nano pores are developed in shale gas reservoirs, and their structural characteristics are important indicators for measuring and evaluating shale gas reservoirs. Organic pores are closely related to the physical properties of shale reservoirs. Through the identification of organic pores, the physical properties of shale reservoirs can be preliminarily judged, which has guiding significance for the exploration and development of shale gas.

[0003] At present, for ...
