| 摘 要： | 通过对鄂尔多斯盆地环县地区15口钻井岩心的岩石学特征、沉积构造、生物化石等特征的综合研究,结合测井资料的详细分析,对环县地区三叠系延长组长8-长6油层组进行了沉积环境分析,结果表明:长8油层组为前三角洲沉积,长7油层组为半深湖—深湖沉积,并发育浊积扇,长6油层组为三角洲前缘沉积;三角洲前缘主要发育在研究区西南部,浊积扇主要发育在研究区的东部。

| Abstract: | Based on the data of the well logging and drilling cores,the authors have observed 15 cores.They have analysed the petrology characters,sedimentary structures,biological fossils of the Chang 8-6 oil formations of Triassic Yanchang Formation in the Huanxian area.All the results suggest that in Chang 6 develops front-delta facies;in Chang 7 develops deep lake to half deep lake facies and turbidite fan and in Chang 8 develops prodelta facies.The front-delta facies is mainly distributed over the southwest of th... |
