Abstract:

The analytical methods of homogenization-temperature and chromatogram-mass spectrum of inclusions are applied to the study of the hydrocarbon charge history of the south slope in Huimin sag.It is suggested that the difference in hydrocarbon charge history is one of the key factors for the differences in hydrocarbon abundance.According to the analysis,the hydrocarbons in Qianguantun were charged in the Mid-Minghuazhen period,while that in the upper and lower reservoirs of Qu-10 well in Quti oilfield were charged in two stages based on the mass spectrum analysis of hydrocarbon inclusions.The conditions of application of these inclusion-testing methods are also discussed in detail.

Key words: homogeneous temperature, analysis of components, episode of petroleum accumulation, fluid inclusion, Huimin Sag
