Description

technical field [0001] The invention relates to an oil and gas exploration experiment device, in particular to a hydrocarbon micro-leakage simulation experiment device. Background technique [0002] The research on the basic theory of hydrocarbon micro-leakage was the most systematic and comprehensive in the former Soviet Union in the early days; the western countries represented by the United States also carried out a lot of research work on it, and obtained meaningful results. Chinese researchers, especially those engaged in oil and gas geochemical exploration, have long been devoted to the theoretical study of hydrocarbon micro-leakage, and have made fruitful efforts. However, due to the extremely difficult simulation of hydrocarbon micro-leakage experiments, most of the views on the basic theory of hydrocarbon micro-leakage have not been verified by systematic experiments, and are still in the stage of hypothesis. [0003] In addition, hydrocarbon vertical micro-seepage...

AI Technical Summary

Problems solved by technology

[0007] However, due to the limitations of analytical testing and material conditions, the different purposes of experiments, and the complexity of vertical micro-seepage of hydrocarbons, the devices for simulating vertical micro-seepage of hydrocarbons at home and abroad have simple experimental conditions and simple experimental devices. The problems solved by the experimental simulation are relatively simple, and there is a large gap between the experimental results and people's expectations for the basic theoretical research on vertical micro-seepage of hydrocarbons

Simple experimental simulation of vertical micro-seepage of hydrocarbons cannot solve actual geological problems, nor can it answer geologists' doubts about the mechanism of oil and gas geochemical exploration, which hinders the development of oil and gas geochemical exploration and its role in oil and gas exploration
