摘要:
四川盆地中侏罗统沙溪庙组是低油价形势下四川盆地天然气勘探的重要领域,但盆地内不同地区天然气来源尚不明确,影响下一步勘探部署决策,为此开展侏罗系沙溪庙组天然气地球化学特征及成因研究。结果表明:①沙溪庙组天然气属于干酪根降解气,甲烷含量>84%,含少量乙烷、丙烷等烃类气体及少量的氮气、二氧化碳等非烃气体,不含硫化氢,不同区域的天然气成熟度存在差别;②天然气δ13C1值为-39.2‰~-31.2‰、δ13C2值为-32.8‰~-22.3‰、δ13C3值为 -28.7‰~-19.5‰,天然气碳同位素未发生倒转,川西地区为煤成气,川中地区为油型气,川东地区为煤成气和油型气混合气,以油型气为主;③不同区域天然气δ13C1值、δ13C2值的差异,与其来源于不同类型烃源岩贡献比例大小有关。川西、川西南地区主力烃源岩为须五段煤系烃源岩,川中地区为下侏罗统湖相烃源岩,川东地区天然气来源于须五段和下侏罗统烃源岩。研究结果对四川盆地侏罗系沙溪庙组下一步天然气勘探部署决策具有重要的指导意义。
