Abstract: The hydrocarbon inclusions of Halahatang-Yingmaili area in Tarim basin could be divided into three stages by observation of microscopic UV fluorescence. The Stage?Ⅰis representative of a highly matured heavy oil charging, the Stage?Ⅱ of a matured medium hydrocarbon charging, and the Stage?Ⅲ of a highly matured light hydrocarbon charging. Based on previous researches of oil accumulation stages in northern Tarim basin, three stages of hydrocarbon inclusions are formed respectively as follows: Stage?Ⅰis that the heavy oil of the Cambrian in late Caledonian movement entered into the Halahatang area and found near Ha?601?1 and Ha?601?2 wells; Stage?Ⅱis that the crude oil of the Middle?Upper Ordovician in late Hercynian movement entered into the Halahatang-Yingmaili area, and Stage?Ⅲ is that the condensate?light oil modified by Yanshan-Himalayan movement entered into the Yingmai?2 area and the southern Halahatang. It is the three?stage hydrocarbon charging and modification that forms the oil?gas properties and features in Halahatang-Yingmaili area nowadays
