Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.
