| Abstract: | The theory of the natural gas hydrate petroleum system is applied to discusses the progress of research on the complex dynamic physicochemical process of natural gas formation and decomposition,the research progress,problems and development trend of the natural gas hydrate petroleum system are analyzed,and the following conclusions are obtained:most natural gas hydrate gas sources are closely related to the biodegradation; the main factors affecting the temperature-pressure critical curve of the natural gas hydrate are the components of natural gas and pore water,while the ground temperature gradient and permafrost thickness do not change the gas hydrate temperature-pressure critical curve; the static elements and dynamic processes at critical moments of the gas hydrate petroleum system and the coupling relationship between them play an important role in the gas hydrate petroleum system.The study of the gas hydrate petroleum system not only provides a theoretical basis for the process of gas hydrate accumulation,but also provides technical support for the exploration and development of gas hydrate. |
