从岩石圈地球动力学特点出发,研究了岩石圈俯冲带含煤建造的生成及其经后期改造生成天然气的机理。例举了北美阿帕拉契亚山前边缘坳陷、落基山逆掩断裂带,西欧诸含煤盆地,东南亚(印尼、缅甸、泰国等)山前坳陷带含煤建造与天然气成藏的关系。详细分析了俄罗斯地台维柳伊—上扬斯克山前坳陷内含煤建造与烃类生成、运移、聚集的关系,并对该区烃类分布进行了预测。指出,丰富的有机质,较短期内快速增高的温压条件,区域地震的活动性是造成岩石圈板块俯冲带内油气生成的主要因素。
Based on the characteristics of the geosphere dynamics of the lithosphere, the formation of coal-bearing structures in the lithosphere subduction zone and the mechanism of natural gas generation after the later transformation were studied. Examples include North America Appalachian front margin depression, Rocky Mountain thrust shield fault zone, Western Europe coal-bearing basins, Southeast Asia (Indonesia, Myanmar, Thailand, etc.) relationship. This paper analyzes in detail the relationship between coal formation and generation, migration and accumulation of coal in the Willow-Jan-Jankers Piedmont Depression on the Russian platform, and predicts hydrocarbon distribution in the area. It is pointed out that abundant organic matter, rapidly increasing temperature and pressure conditions in a relatively short period of time, and the activity of regional earthquakes are the main factors that cause hydrocarbon generation in the subduction zone of the lithospheric plate.
