| 摘 要： | 物源问题的研究对于了解和确定研究区有利沉积相带及储集砂体的分布、寻找有利油气储集层具有重要意义。胜坨地区沙四上勘探程度相对较低,前人关于目的层段的物源体系的研究成果很少。为了进一步查清研究区沙四上沉积时期砂体成因和物源方向,更好地预测砂体的分布,本文综合运用地震、测井、地球化学等资料,采用古地貌分析法、沉积砂体岩屑类型对比法、砂岩百分含量法和沉积物特征元素等方法探讨了胜坨地区沙四上亚段砂体的物源方向,并结合特征元素物源指数判别公式对沙四上亚段物源体系实现了定量评价。综合分析认为研究区沙四上亚段具有多物源体系特征,除了直接来自于胜北断层和坨94断层上升盘的物源外,还有沿着胜北断层与坨94断层转换带处的物源体系。

| Abstract: | The study of sediment source is significant in understanding and identifying favorable sedimentary facies belts and distribution of reservoir sands in the study area as well as in prospecting for favorable oil and gas reservoirs.Because the exploration extent of the 4th Member of Shahejie Formation is at a relatively low level in Shengtuo area,previous researches on the purpose layer sedimentary source system is very insufficient.The authors studied the source direction of the Upper 4th Member of Shahejie F... |
