Helium was used as the carrier gas under a constant pressure of 206 kPa. The oven was programmed at a rate of 5 ℃/min from 90 ℃(held for 5 min) to 280 ℃(held for 5 min).

载气为氦气，恒压，柱前压206 kPa；进样器温度250 ℃；柱箱初始温度为90 ℃，保持5 min，以5℃/min的升温速率升至280 ℃，保持5 min。

Huangqiao carbon dioxide gas field in North Jiangsu Basin have the following characteristics: deep gas fields are associated with shallow ones, marine gas fields are coupled with continental ones, and several gas reservoirs are combined. Carbon dioxide in Huangqiao area mainly comes from deep mantle, mixed with a little thermal metamorphism and a little organic carbon dioxide in shallow formation, and helium and nitrogen gas mainly come from mantle. There is a good time\|space matching relationship between carbon dioxide gas reservoirs and great rifts, magma and volcano activity, which forms the special carbon dioxide gas reservoir mode for Huangqiao. This mode has good sealing, trapping and preserving conditions, but its gas source differs from traditional hydrocarbon gas reservoirs.
