以甲烷为主的天然气是最清洁的能源资源之一,但是目前还没直接的方法用以确定其烃源岩.为此,本研究分析了川东地区天然气地球化学和地震资料,确定热化学硫酸盐还原（TSR）等次生过程对天然气的改造作用,并探讨了天然气的来源.研究结果表明,第一类天然气分布于开江-梁平地区周围上二叠统-下三叠统（P3ch-T1f）,其挥发性有机硫化合物（VOSCs）δ34S值与伴生H2S相近,可能经历了以甲烷为主的TSR作用;随着TSR程度的增强,甲烷δ13C1值发生正偏移.第二类来自川东地区的下石炭统-中二叠统（C2h-P2q）以及南部地区的天然气,未受到明显的TSR影响,天然气中某些VOSCs与干酪根之间的δ34S值相似,可能来自下志留统和中二叠统的烃源岩.本研究提出VOSCs的δ34S值可作为非TSR改造天然气与烃源岩直接对比的指标.天然气和烃源岩地球化学数据与地震数据相结合,可以作为一种有效勘探天然气藏的方法.
