Abstract

The invention provides a device for analyzing a hydrocarbon component of a monomer oil gas inclusion, which comprises a microscopic laser denudation system, a hydrocarbon component enrichment desorption system and a hydrocarbon component separation analysis system. An analyzing method using the device comprises the following steps: determining a monomer inclusion used for experiments under a microscope, opening the inclusion by using the laser denudation system, and releasing oil gas components without change; feeding the released oil gas components after the treatment of the hydrocarbon component enrichment desorption system into the hydrocarbon component separation analysis system along with a carrier gas; and selecting a detector according to the analysis demand to analyze the oil gas components so as to determine the components thereof. Through the device and the method, the hydrocarbon components of the inclusions of different periods can be effectively prevented from being mixed, and the hydrocarbon components are not changed during the denudation. The device and the method effectively enrich trace organic components to meet the detection requirements of the conventional analytical instruments. In addition, the device and the method can comprehensively analyze the gas-liquid components of the monomer oil gas inclusion, and can serve the oil-gas geological exploration better.

Description

technical field [0001] The invention belongs to the field of analyzing organic components in inclusions of rock samples, and in particular relates to a hydrocarbon component analysis device and method for single oil and gas inclusions. Background technique [0002] Since the 1980s, the use of fluid inclusion geochemical methods to solve problems such as accumulation and diagenesis has become a popular research topic, and the characteristics of fluid inclusions (inclusion size, shape, and inclusion phase state, etc.) are often used in research. ), temperature and composition. The research on the composition of inclusions mainly includes group inclusion analysis and single inclusion analysis. The compositional analysis technology of population inclusions adopts destructive analysis methods, including crushing method and thermal burst method. The analysis of population inclusion composition can be realized by online connection of crushing (thermal burst) device and chromatogr...
