文摘
- •
Carbon isotopic compositions of alkane gases in Zizhou gas field are heavy.
- •
The contents of C5–7 isoalkanes and methylcyclohexanes in the gases are high.
- •
Gases in Zizhou gas field are typical coal-derived gas.
- •
The gases were generated by mature to high-mature C–P coal measures.
- •
Mixture of gases of different maturities caused a carbon isotopic reversal.
