“…The geological setting of the petroleum systems of the Liaohe Basin has been summarized by numerous authors (e.g., Koopmans et al, 2002;Tuo et al, 2003;Fuhrmann et al, 2004;Huang et al, 2004;Hu et al, 2005;Gu, 2016). The Liaohe Basin, located in northeast China, is one of the secondary tectonic elements of the Bohai Bay Basin groups (Fig.…”

The molecular and isotopic (C and H) compositions of Paleogene [Shahejie Formation (E 2-3 s) and Dongying Formation (E 3 d)] natural gases from 11 new gas samples as well as the data of 71 gases published from previous studies in the Liaohe Basin were analyzed, and the results were considered in combination with geochemical and distribution characteristics of the source rocks. The genetic type, gas-source correlation and secondary alteration of the natural gases were studied in detail, and the source rock maturities of the gases were estimated. The following conclusions were reached: (1) with the exception of dry gases in the major part of the third member of the Shahejie Fm. (E 2 s 3) reservoirs, the gases in other reservoirs are mainly wet; (2) variable carbon and hydrogen isotopes of the alkane gases are observed in different reservoirs of the basin with δ 13 C 1 values ranging from −60.7 ‰ to −34.2 ‰, δ 13 C 2 from −47.3 ‰ to −22.3 ‰, δ 2 H CH4 from −261 ‰ to −188 ‰, and δ 2 H C2H6 from −269 ‰ to −148 ‰; (3) the natural gases of the basin are of multiple origins, and mixing of thermogenic and microbial is observedthe mixing ratio in the first member of the Shahejie Fm. (E 3 s 1) is the highest among all the reservoirs; (4) gases of different reservoirs suffered varying extents of biodegradation, which caused partial reversal of the carbon isotope series of methane and its homologues (δ 13 C 1 < δ 13 C 2 < δ 13 C 3 > δ 13 C 4); the reversal of the gases in the shallow reservoirs (E 3 s 1 and E 3 d) is greater, while those in the deep reservoir (E 2 s 3) is less; (5) humic natural gases of the ED were mainly generated by source rocks at early maturity, while the sapropelic ones of the ED and WD were generated during the mature and high mature stages; (6) both the source rocks of E 2 s 3 and E 2 s 4 strata could contribute to the gas reservoirs of E 2 s 3 and E 2 s 1 in the west depression. Sapropelic gases in east depression were generated by E 2 s 3 source rocks, while the other gases reservoired in the E 2 s 3 , E 3 s 1 , and E 3 d strata are probably sourced from the source rock strata of E 2 s 3 and E 3 s 1-2 .

“…Liaohe Basin is located in the Liaoning province, adjacent to Bohai Bay. It is a wedge shaped rift basin and has experienced a complex structural evolution (Huang and Pearson, 1999;Hu et al, 2005). The Es 4 and Es 3 members of the Eocene Shahejie Formation are the main source rocks in this basin (Hu et al, 2005).…”

“…The rift heat flow model, which incorporates a higher heat flow period during the rift phase and an exponential reduction during the post-rift phase (Mckenzie, 1978), has been widely used to calculate the palaeo heat flows in rift basins (e.g., Justwana et al, 2006;Hu et al, 2005;He and Middleton, 2002;Guo et al, 2011). The increase in heat flow during the post-rift phase is related to the lithospheric thinning, which influences heat entering the basin from the asthenosphere.…”
