| 摘 要： | 通过对鄂尔多斯盆地延长组长6期湖盆中部地区物源分析、沉积相特征等研究,分析了厚层砂体的形成机理和砂体类型。认为长6期物源主要来自东北、西南方向,发育三角洲前缘水下分流河道、河口坝、远端砂坝和浊流等砂体类型,湖盆演化从鼎盛转向萎缩的长6早期厚层砂体比较发育。白豹、合水地区砂层厚度大,储层条件良好,是石油勘探的有利地区。

| Abstract: | By source analysis and researches on the sedimentary characteristics, the formation mechanism and types of the thick sand bodies in Chang 6 period in central lake basin of Ordos basin is studied. The source of sand bodies is situated in the northeast and the southwest where the sedimentary facies include submerged distributary channel, mouth bar, distal bar and turbidite. The thick sand bodies developed in the early Chang 6 period when the lake basin transformed from raise to fall. Baibao and Heshui areas are the favorable zones for oil exploration due to the features of great sandstone thickness. |
