Hydrocarbon source systems and formation of gas fields in Sichuan Basin

Hydrocarbon source systems and formation of gas fields in Sichuan Basin

The formation of large and middle gas fields in Sichuan Basin is investigated based on source controlling theory and hydrocarbon source systems. It is indicated that (?)1, S1, P1, P2 and T3 are the main source beds and (?)1/Z2d, C2h/S1, P1/P2, P2ch/P2, T1,2/P, T3x/T3x are important hydrocarbon sourc...

Zusammenfassung:The formation of large and middle gas fields in Sichuan Basin is investigated based on source controlling theory and hydrocarbon source systems. It is indicated that (?)1, S1, P1, P2 and T3 are the main source beds and (?)1/Z2d, C2h/S1, P1/P2, P2ch/P2, T1,2/P, T3x/T3x are important hydrocarbon source systems in the basin. All these source systems are the prospective formations and exploration spaces of large and middle gas fields. It is also emphasized that hydrocarbon generation intensity is the most important geochemical factor to estimate large and middle gas fields.
