对采自四川盆地二叠系茅口组、长兴组和三叠系飞仙关组、嘉陵江组、雷口坡组、须家河组以及侏罗系59个天然气样品的C5—C7轻烃化合物进行了对比研究，指出这些天然气的轻烃主要有3方面的作用：①反映母质类型，川西南部须家河组天然气富含环烷烃和芳烃，川中—川南地区须家河组天然气富含环烷烃，表明这些天然气的母质类型主要为腐殖型；②反映运移相态及水洗作用，川中—川南地区须家河组天然气芳烃分别与正己烷、环己烷、正庚烷参数的比值与其伴生凝析油的相近，主要以游离相运移，而天然气轻烃组成具高链烷烃、低芳烃的特点，主要原因是天然气在运移成藏过程中芳烃受到水洗作用的影响；③反映原油裂解气特征，二叠系茅口组—中三叠统雷口坡组以海相腐泥型为主的天然气轻烃富含甲基环烷烃，是原油裂解气的一种标志。

The C5-C7 light hydrocarbon compounds in 59 natural gas samples collected from the formations of Permian (Maokou,Changxing),Triassic (Feixianguan,Jialingjiang,Leikoupo,Xujiahe) and Jurassic in Sichuan basin were studied and contrasted thoroughly.The light hydrocarbon have play an important part in three aspects in Sichuan basin.①Identifying the types of organic matter.The light hydrocarbon composition of the natural gas of Xujiahe formation in southwestern Sichuan basin is of the characteristic of high naphthenic hydrocarbon and aromatic hydrocarbon,but in middle and southern Sichuan basin is of high naphthenic hydrocarbon.It is supposed that the natural gases mainly originated from the humic organic matter.②Reflecting migration phase and water washing.The ratios of aromatic hydrocarbon to n-hexane,hexamethylene,n-heptane,respectively in natural gases in middle and southern Sichuan basin are very close to that of gas condensates.It is concluded that the light hydrocarbon is of high paraffin and low aromatic hydrocarbon is mainly concerned with the water washing during migration.③Indicating the characteristic of crude oil cracked gas.The light hydrocarbon in gases mainly originated from marine sapropelic organic matter in Maokou to Leikoupo formations is of high methyl-cyclohexane.It is a sign of crude oil cracked gas.
