应用包裹体均一温度法及色谱-质谱分析法对济阳坳陷惠民凹陷南斜坡油气充注史进行研究,表明充注史差异是造成该区油气富集程度不同的原因之一。分析发现钱官屯地区油气为明化镇中期充注,而曲堤油田曲10井上下储层的油气包裹体质谱分析结果显示包裹体成分存在差异,是两期充注的结果造成,并进一步有针对性地阐述了包裹体测试方法的适用条件。

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.
