鄂尔多斯盆地南部油页岩矿有利勘探区预测

摘要

Based on the geochemical and logical analysis of oil shale samples in southern Ordos basin , The characteristics and distribution of oil shale from Yanchang Formation have been investigated .The result shows that oil shale has the typical identification marks .The thickness of oil shale is 10 ~ 40m ,the distribution of which is significantly controlled by the sedimentary environment .Deep lake and semi deep lake facies which is near the central of lake basin is the main development zone for the development of oil shale .Oil shale is developed at Binchang area ,the north of xunyi and the southwest of Fuxian ,which becomes the favorable area for exploration .%基于对鄂尔多斯盆地南部延长组油页岩样品的地球化学和测井资料的分析，研究了研究区延长组油页岩的特征及其分布规律。研究结果表明，油页岩具有典型的识别标志，它的厚度10～40m ，分布受沉积环境的控制作用明显，靠近盆地中央的深湖～半深湖相沉积区是油页岩的主要发育地带，彬长地区，旬宜地区北部及富县地区西南部的油页岩相对发育，是油页岩矿勘探的有利区。
