The system can perform a test for artificial synthesis of the fluid inclusion under conditions of common temperatures and pressures of an oil-gas containing basin reservoir, simulates a formation mechanism of the fluid inclusion in reservoir minerals and interaction between reservoir rock and a fluid, can allows a crude oil or natural gas component to be added into a test system, performs test simulation of influence of oil gas injection on formation of the reservoir fluid inclusion, and achieves real-time online sampling analysis.

Description

Technical field [0001] The present invention belongs to the field of geochemistry. Specifically, it relates to a system for artificial synthesis of oil and gas fluid inclusions, which simulates the artificial synthesis of oil and gas fluid inclusions under the conditions of basin reservoir temperature and pressure, and can simulate oil and gas reservoirs. Water-rock interaction mechanism. Background technique [0002] In recent years, with the gradual deepening of research and application of fluid inclusion technology, synthetic fluid inclusion technology has become an important technology for preparing fluid inclusion standard samples, and can simulate the formation of fluid inclusions in certain geological environments. However, the existing synthetic fluid inclusion systems are mainly aimed at high temperature and high pressure ore-forming fluid conditions. The experimental temperature and pressure conditions are far greater than those of petroliferous basins (large errors und...

AI Technical Summary

Problems solved by technology

However, the existing artificially synthesized fluid inclusion systems are mainly aimed at the conditions of high-temperature and high-pressure ore-forming fluids, and the experimental temperature and pressure conditions are much higher than those of oil and gas basins (the error is large at low temperature and low pressure). More importantly, the existing equipment generally uses gold tubes. Or platinum tubes are used as reactors (generally several mL in volume), resulting in small volumes and small quantities of synthesized samples, which are not suitable for the study of artificially synthesized fluid inclusions under the conditions of oil and gas basins.
