Rock thin section analysis data show that pack bitumen exists in the reservoir of Ordovician weathering crast of Chuntan1, Futan1 and Shan54 wellblocks in central uplift belt. The pack bitumen with high maturity is proved to be remnant of oil pyrolysis by the optical feature, which proves the existence of paleo-oil reservoir. The paleo-oil reservoir is located in the downdip direction of the Jingbian gasfield and the shale of the Middle Ordovician Pingliang Formation with abundant organic matter might be the source rock of the paleo-oil reservoir. The increasing of its buried depth and palaeogeotherm in the stage of J2-K1 caused Paleo\|oil reservoir to turn into Paleo-gas reservoir. Shanbei slope was formed by the Yanshan movement during K2-E. The gas in central Paleo-uplift zone migrated to the high place of slope and formed Jingbian gas field by lithology sealing.
