| 摘 要： | 通过塔河地区西南部古生界东河塘组岩心油显示及含油薄片分析,以及首次应用红外光谱石油基团成份测定技术,对该地区东河塘组油气运移痕迹做了一次系统的研究。结果表明:东河塘组油气具有同源性;轻质油成份南北有所差异,重油或沥青与轻质油分属不同期的产物;北部井多分布重质油和沥青,向南减少,轻质油增加,北部和中北部井多出现水驱特征。在运移痕迹研究的基础上,结合地质背景及前人的研究成果,分析了石油的运移路径,为建立正确的油气运聚模式提供依据。红外光谱法对研究运移痕迹很有效,应该成为今后油气运移研究技术方法之一。

| Abstract: | In the paper,the hydrocarbon migration vestige of Donghetang formation in the south-west of Tahe oilfield is studied systematically by analyzing oiliness cores and slices and using Microscope infrared spectroscopy(Micro-FTIR) technique,which was used to this study for the first time.Results indicate that: oil and gas in Donghetang formation have the same sources;the components of light oil in the southern are different to the northern;the heavy oil either the asphalt with the light oil are formed in the different time;the northern wells have much heavy oil and asphalt,but more closer the south,more lighter oil is;the northern and middle northern wells can be often find the phenomena of water driving.On the base of vestige's study,consulting the geologic information and some geologists' works,we can analyze the hydrocarbon migration's path,and provide proofs for building the right accumulation model.Micro-FTIR is useful for our study,and should be a technique for migration study in the future. |
