Abstract

In order to determine the hydrocarbon filling and accumulation period of Chang 9 oil reservoir set in Ansai area, based on the microscopic observation of fluid inclusion, fluorescence analysis and micro thermometry of associated saline inclusion in quartz overgrowth boundary, combined with the simulation of burial-thermal evolution history of Chang 9 oil reservoir set, the hydrocarbon migration and accumulation time were confirmed. The result shows that Chang 9 oil reservoir set mainly developed saline inclusion and liquid hydrocarbon inclusion. They mainly distributed in the overgrowth edge of quartz and its dissolved fractures, with circular and irregular forms and the size of 2~6 μm. The homogenization temperature shows unimodal distribution, and mainly ranges from100 ℃ to 110 ℃. One time of hydrocarbon charging occurred in Chang 9 oil reservoir set, corresponding to the middle and late period of Early Cretaceous ( 100~120 Ma ) in the geological history.
