求翻译：从中下二叠统到上二叠统油气藏的纵向序列来看，天然气组分中甲烷含量逐渐增加，乙烷－丁烷含量和δ13C1~4则不断减小，气藏压力和丰度规模也显著降低；上二叠统含油气层段表现为低压力系数(94~97%)、较轻δ13C1值(－37.1 ~ －36.2)‰、较低C2~4和C4以上烃含量(是什么意思？ 待解决

From the Lower Permian to Upper Permian reservoirs of the vertical sequence of view, methane content in gas composition in a gradual increase in ethane - butane content and δ13C1 ~ 4 are constantly decreases, gas pressure and abundance scale significantly reduced; Upper Permian oil and gas bearing s
