Since the Paleogene，the Dongpu depression has experienced two stages of tectonic movements，at the end of sedimentation of the Dongying Formation and in the late period of sedimentation of the Minghuazhen Formation respectively.These tectonic movements putgreat influence on hydrocarbon generation of the deepˉburied source rocks and the forming ofoil/gas pools in shallow strata.On the basis ofburialhistory reconstruction and previous studies on thermal evolution，we reconstruct the hydrocarbon generation history of source rocks in the thirdmember of the Shaheˉjie Formation since Paleogene，discuss the influence of tectonicmovements on hydrocarbon generation of source rocks in the thirdmember of the Shahejie Formation and analyze its implications for the forming of oil/gas pools in shallow strata.According to the results，it is believed that（i）the great strength of the DongyingMovement restrained and delayed hydrocarbon generation of the deepˉburied source rocks，which led to the massive hydrocarbon generation after the DongyingMovement;（ii）the DongyingMovement preserved the hydrocarbon generation potential of the deepˉburied source rocks，which laid foundations for secondary hydrocarbon generation when the source rocks were buried deeper and the forming of oil/gas pools in the late period of sedimentation of theMinghuazhen Formation.
