Principium and method of ascertaining oil-gas pools age with inclusion are introduced. Based on homogenization temperature test of inclusion, resuming of hot history and hydrocarbon producing history, the infusing degrees and infusing time of Tiandong-19 well, Mo-13 well and Pingchang-1 well are investigated according to inclusion. There are three periods of oil-gas to infuse in Tiandong-19 well and Mo-13 well. Infusing time of three periods of oil-gas in Tiandong-19 well are respectively early Trias, early midlle Jurassic and upper midlle Jurassic. Infusing time of three periods of oil-gas in Mo-13 well are respectively early-midlle Jurassic, midlle-upper Jurassic and upper Cretaceous- early Tertiary. There are two periods of oil-gas to infuse in Pingchang-1 well. Infusing time of two periods of oil-gas in Pingchang-1 well are respectively midlle-upper Jurassic and upper Jurassic-early Tertiary. Finally, some questions to be regarded about ascertaining oil-gas pools age with Inclusion are point out.
