摘要
目的探究鄂尔多斯盆地晚三叠世层序中最大湖泛泥岩的分布特征及其石油地质意义,以便更好地进行油气田勘探。方法根据区域地质调查、测井、岩心和野外典型剖面的观察及地球化学资料,并运用层序地层学原理进行分析。结果最大湖泛泥岩的分布受湖盆底部形态的控制呈现区域性变化,该套湖泛泥岩是鄂尔多斯盆地三叠系延长组层序中最好的一套优质烃源岩。结论最大湖泛泥岩的展布对油气运移和富集具有一定的控制作用。
Aim To study mudstone distribution character in maximum flooding time and its significance of petroleum geology for the purpose of exploration of oil and gas field.Methods According to regional geological surveying,logging,core,field typical geologic section and geochemical datum.Results Distribution of the mudstone in maximum flooding time was controlled by the lake basin bottom shape,which presents regional variation.The mudstone is quality source and dominates primary migration and concentration.Conclusion It was a guidance to forecast the distribution of the oil reservoirs.
