摘要
以测井、岩芯及野外露头等资料为基础,对鄂尔多斯盆地姬塬北地区上三叠统延长组长6油层组三个小层泥岩厚度进行全面系统的统计,分析了长6油层组三个小层的泥岩厚度变化的规律和河道侧向迁移特征,阐述了该区泥岩分布范围较广、厚度大、分布不稳定,呈小团块、条带状,为多套深灰色、深褐灰色泥页岩,表明长6油层组泥岩发育,具有较大的生烃潜力。
Based on the data of well logging, drill core, field outcrop, etc., conductes comprehensive and systematic statistics of the thickness of three small mudstone layer in Chang-6 oil layer group of Yanchang Formation of upper-triassic in Northern Jiyuan of Ordos, analyzes the change regulation of the thickness of three small mudstone layer in Chang-6 oil layer group and the lateral migration characteristics of river course, and elaborates that the mudstone in this area is of wide distribution, large thickness, unstable distribution, showing small clumps or banded shape, and most of it is many sets of clark gray, sepia gray mud shale, which indicates that the mudstone of Chang-6 oil layer group develops with greater hydrocarbon potential.
