Ordos Basin is an important large petroliferous basin in China. In order to recover gas generation history and evaluate gas resources of Pingliang shale in Weibei Uplift, Ordos Basin, we took the Pingliang shale of Well XT-1 as the research target. We reconstructed burial and thermal histories of Pingliang shale based on PetroMod software. Besides, we also recovered gas generation history and its resources potential. The modeling results show that Well XT-1 had experienced five major tectonic stages. The burial depth of the bottom of Pingliang shale reached the maximum with the value of approximately 4500 m at the late Cretaceous and the current burial depth is 3068 m. The results of thermal history show that Pingliang shale had experienced oil-generation and gas-generation stages and current Ro is 2.52%. Based on the calculation results about gas generation history, generation masses of methane, wet gas, and total gas are 1.24 × 10 8  kg/km 2 , 0.88 × 10 8  kg/km 2 , 2.12 × 10 8  kg/km 2 , respectively, which shows great gas resource potential of Pingliang shale in Weibei uplift, Ordos Basin.
