In this paper, the author studied the main forming time of Gaotaizi oil reservoir and the period of accumulation of oil and gas of Heidimao structure in Daqingzi region, besed on the research results of reservoir's organic inclusions, the history of generation and discharge of hydrocarbon, the evolution of structure, and the conditions for oil and gas migration and accumulation. The petroleum accumulation occurred mainly at the end of Mingshui period and Tertiary. The reservoir's organic inclusions have high abundance in this time; they recorded the main period of petroleum accumulation.
