  • Thermal modelling of gas expelled from source rocks of Yacheng Formation and Meishan Formation in Ying-Qiong Basin was made.

Abstract: Thermal modelling of gas expelled from source rocks of Yacheng Formation and Meishan Formation in Ying-Qiong Basin was made. The total amount of gases generated and expelled from Yacheng Formation is larger than that from Meishan Formation, suggesting that the gas generation potential of Yacheng Formation is higher than that of Meishan Formation. The similarity of the percentage of C1, C2-C4 and C5-C7 of the gases from Ya13 -1 field to that of the normalized gases produced at high evolution stage implies that the gases of Ya13 - 1 field may come from the source rocks with high maturity. There are similarity and difference between the composition of C6 and C7 of the gases from Ya13 -1 field and that of the normalized gases produced during the experiment. The stable carbon isotope composition of the saturated fraction of the condensate of Ya13 - 1 field and the extracts of Yacheng Formation, Meishan Formation, Ying-Huang Formation indicates that the gases of Ya13 - 1 gas field may come from multiple source rocks.
