摘要
四川晚二叠世龙潭组煤系中普遍富含重烃气体。含量达20%~5O%。其原因与煤层有机质的性质、含量、有机变质作用以及煤层物性和煤层油气运移性等因素有关。
Heavy hydrocarbon gas is commonly richened in Longtan coal series of Late Permian in Sichuan and its content is high up to 20 %~50 %, which is attributed to these factors as the properties and contents of organic matters contained in the coal beds, the organic metamorphism, the physical properties of the coal beds and the migratory aptitude of oil and gas in the coal beds, etc..
